When you call df2.cache(), Spark begins to cache the result of the DataFrame df2, but the action to materialize this cache is still delayed until the action is executed.
The transformation pipeline is executed two times when the df2.cache() call is made and df2.show() is executed.
The correct order of executions is below: Make changes in your code:
df2.count() #Transformations will be materialized
df2.cache()
df2.show() # Now it fetches from the cached data
Following discussions like this and related Stackoverflow posts like this Google Sheets seems to be lacking the capability of fetching sites that uses dynamic data. Also, the site that you are trying to access may also be implementing ways to avoid web scrapers from accessing their data. I tried scraping it using Apps Script but it gave almost the same data as you are getting (seen from the screenshot you provided).
Output Using Apps Script
You can check this SO post for possible ways to scrape a dynamic website like the one you are trying to.
I was lacking the role, and then I was assigned the Global Administrator role. After that, I had to sign out and sign back in. It asked me to update my password, and then it worked.
destruct <term> replaces all occurrences of <term> with a constructor applied to its arguments (which are generated as variables in the context), with one goal per constructor. With an evar, you can choose which constructor should be applied by doing the instantiation yourself, e.g. with instantiate (p := (?[p1], ?[p2])).

Try to take a look at the HTTP reply headers; there should be a redirect with the target address. With high probability, the Upstream - the Jenkins generating these links and including its original address, which is 8888 port. You can repeat the test with and w/o a reverse proxy and compare the header value.
If it's true - try to find "main" URL in the Jenkins settings.
First of all, you need to localize the root cause:
Does the download speed(or throughput) change over time and is lower than usual for the problematic sites/pages? Try to download test data samples in parallel from the other domain. And add Mbit/s metric to monitor the target sites. It will help you to find out if the target sites limiting you or not. If so - try to spread the data flow among unique IPs. The basic principles can be found here datascrape.tech/blog/pyramid-of-efficient-scraping
2.Double-check the pages/URLs queue size. It might be that you have local maximums of URLs number and this causes the problem, not the network throughput.
Double-check that you haven't reached your VPCs throughput maximum. Haven't checked that recently, but usually
throughput(network speed) depends on the disk size and is limited by
default for the VPCs.
What exact risk has your penetration test highlighted?
If both front and back authentification and authorize your users the right way - it's not clear to me why direct access to the front is good and direct access to the back is not.
Solutions that have been mentioned in the previous answer, like AntiDDOS, Application layer Firewall, AntiBot scoring, etc, are useful. But have to put them before the front and back.
this might have been caused by any DEPRECATED imports in the app.module that can be identified by running "ng serve --prod" which will show the error .

I have the same issue. Any solutions?
Issue is that our company security scanners scans all possible URLs of APIM. Even the ones which not exist. We also have alerts enabled, so whenever security scan is done we receive alerts that smth is down.
Okay I got a tip from r/cloudflare that if you enable Strict SSL, it would work. And it did. No idea why, but posting here if someone has the same problem.
As @dacort mentioned, The memory shown in the Spark UI is different than the memory allocated for the executor, it's the memory available for storage (a fraction of the total memory). See https://stackoverflow.com/a/47014697/5141922
Fetch all posts by the two users which were created in the last year with the help of the fromdate parameter. Note that user ids are semicolon separated.
Fetch the (public) reputation history of the two users, filter out the events regarding posts whose ids were not returned in the previous API call, and sum the reputation_change fields of all the remaining events.
Here's a Python implementation, which uses StackAPI:
from stackapi import StackAPI
from datetime import datetime
from dateutil.relativedelta import relativedelta
year = (datetime.now() - relativedelta(years=1)).timestamp()
SITE = StackAPI('stackoverflow', key = '') # add your key
# fill user ids
user1 = 0
user2 = 0
# fetch all posts by user1 and user2 in the last year
posts = SITE.fetch(
'users/{ids}/posts',
ids=[user1, user2],
filter='!*Ju*n-1rscDl8QtK',
fromdate=round(year)
)
ids = [item['post_id'] for item in posts['items']]
# fetch the reputation history of user1 and user2
history = SITE.fetch('users/{ids}/reputation-history', ids=[user1,user2])
total1 = sum(item['reputation_change'] for item in history['items'] if item['post_id'] in ids and item['user_id'] == user1)
total2 = sum(item['reputation_change'] for item in history['items'] if item['post_id'] in ids and item['user_id'] == user2)
print(total1)
print(total2)
I assume that this is experimental - where you have control of both ends of the exchange yourself, rather than trying to actually use an emulator in place of a smart phone for communicating WITH OTHERS via SMS. Because numerous other sources say that the latter simply isn't possible, due to how the data is transferred: through cell systems, not over "the internet" per se.
I feel daft, but I dont see how the code helps you resume from where an error/exception is thrown. I have a similiar issue with a script that takes days to execute, and thus can get stuck or "die" for various reasons. I need it to resume where it stopped without me intervening.
My current go-to-solution is saving pickle files and reopening them, but not sure it is the most efficient one.
For now using expect(page.locator).toMatchAriaSnapshot() method is possible only in scope of Playwright Test runner since the matcher checks testInfo and takes a snapshot dir path from there:
The typical workflow would be to launch your application through the RenderDoc UI, check if the module (dll/so) is loaded, and use the in-application API if it is available, but this is not strictly necessary. You should be able to just preload the relevant module, verify it is open in your app in the same way, and use the API that way without going through the UI.
During the first call, since x is not defined, the else block is executed. In the else block, x is declared as a global variable. During the second call, since x was defined in the else block during the first call, the condition evaluates to true.
The problem isn't with your rotation logic - it's with the assumption that you're dealing with ARGB data.
If you're getting the buffer from the camera (which I suspect you are), it's actually in YUV format, not ARGB. That's why vImageRotate90_ARGB8888 crashes - you're telling it to rotate data in a format that doesn't match what's actually in memory.
There are two ways to fix this:
If you're dealing with camera buffers (YUV format):
You need to rotate the Y and UV planes separately
Each plane needs its own vImage rotation call
Make sure to lock/unlock the buffers properly
For everything else:
Skip vImage altogether and use VTImageRotationSession
It's way more reliable and handles all the format stuff for you
Less code and fewer crashes
The real gotcha here is that camera buffers are almost always YUV, not ARGB. Once you handle the planes correctly, the rotation works fine.
Thanks to skink's answer I could go through different articles about smart and dumb components. Actually what I was looking for relies in BehaviorSubject of RxJS: by creating an additional service, we can notify the DataComponent that an action was performed, without worrying about that it is far away from the relation parent-child. Not sure about the over-using of this approach, but in my case it seems to work fine.
(Unsure where should I put this but wanted to list potential actionable solutions can be done other than already listed by other answers)
...given that each thread called it with its own arguments and no threads are relying on anything global or shared. When I used 4 threads, the time for some reason went up from 315 sec to 710 seconds, and when I used 8 threads, the time went up to 1400 seconds, even though each thread is doing exactly the same work that the one thread without multithreading was doing, and was taking 315 seconds to complete. So, what the hell??
Answer: Most likely you are observing contention in glibc malloc with heavy usage of malloc and there two possible options to achieve fix it.
A. Use Mimalloc instead of GNU Libc's malloc
Mimalloc is a general purpose allocator library with great benchmark result. It consistently outperform GNU Libc's performance in various benchmark performed by mimalloc[1]
Requirement: Willing to use mimalloc as dependency of your program/library/project
Reason: Don't have internal point of contentions[2] so any contention observed disappear under mimalloc and you should observe the performance you're looking for.
Application: Mimalloc can replace your malloc and free function dynamically[3] through LD_PRELOAD case of your glibc based system[4] or statically linking Mimalloc[5]
B. Object pools
A pattern inspired from Java which the idea is reusing existing allocated objects so as to avoid overhead of creating and destroying them.
Which when to C mean keeping list of existing allocated instances of objects to be reused later avoiding overhead of lots of malloc/free for short lived objects
Requirement: Your program has lots of short lived object, most of short lived object is the same size and type and preferably have clear point where you can deallocate whole pool (e.g. before returning calculation result)
Reason: Minimize the time taken spent in malloc/free by reusing previous instance of same object which just recently free'd by current thread as written in your question that those threads share nothing
Thanks for the suggestions. In the end, I moved away from the idea of configuring my own logging, and instead just used print statements and fetch the logs from Cloudwatch right before the function exits.
In my case, the problem was solved by manually calling the garbage collector using gc.collect() after the with block.
I believe this does not agree with the multiprocessing documentation. There, it is suggested that a context manager is sufficient to properly handle the resources and that we should not rely on the garbage collector to do it.
Warning
multiprocessing.pool objects have internal resources that need to be properly
managed (like any other resource) by using the pool as a context manager or by
calling close() and terminate() manually. Failure to do this can lead to the
process hanging on finalization.
Note that it is not correct to rely on the garbage collector to destroy the
pool as CPython does not assure that the finalizer of the pool will be called
(see object.__del__() for more information).
The problem of this post is solved. Thanks to @shingo and @Polynormial. The list has two reference of the anim instance, and the IndexOf returns the first one.
I think I know what may caused the situation after all. It's a reference I didn't cleaned up before releasing into the pool, and that dirty reference was at the index of 1 in the list. So after releasing it into the pool and getting it out, then adding it again at index of 29, the one at index 1 still exists.
Thank you so much for your clear answer. Im starting to understand now (I think :-)).
If im correct the only thing I need to do is change the 'payment_id' with my Mollie ID?
Do I need to include the code "// For other payment gateways than Mollie" ? Because im not using any other payment gateway. I think it will look like this?
// Utility function: Get the custom order status by product category
function get_custom_order_status_by_cat( $order, $status = false ) {
// Loop through order items
foreach ( $order->get_items() as $item ) {
$product_id = $item->get_product_id(); // Get product ID
if ( has_term( 'met-gravure', 'product_cat', $product_id ) ) {
$status = 'ord-maatwerk'; // Aangepaste status
break;
} elseif ( has_term( 'moedermelk', 'product_cat', $product_id ) ) {
$status = 'ord-moedermelk'; // Aangepaste status
break;
} elseif ( has_term( 'last-minute-gepersonaliseerd-juweel', 'product_cat', $product_id ) ) {
$status = 'ord-lastminute'; // Aangepaste status
break;
}
}
return $status;
}
// For Mollie Payments
add_filter( 'woocommerce_payment_complete_order_status', 'update_order_status_by_category_for_mollie', 10, 3 );
function update_order_status_by_category_for_mollie( $status, $order_id, $order ){
// HERE bellow, define Mollie payment method ID
$targeted_payment_id = '*******';
$custom_status = get_custom_order_status_by_cat( $order ); // Get custom order status
// If a custom order status is found and if it's a Mollie payment
if ( $custom_status && $order->get_payment_method() === $targeted_payment_id ) {
return $custom_status;
}
return $status;
}
According to the stacking order, this issue occurs when the div.relative has a higher stacking order than the div.sticky (the div.sticky appears before the div.relative in html).
There is no solution without z-index.

You can import ESM modules (including pure ESM modules, like `p-limit), in CommonJS.
The reason this does not work in a TypeScript module, is because the TypeScript compiler converts the import() to a require(). The asynchronous import(), also called dynamic import, is requried to load an ESM module.
The following code will load an ESM module in a CommonJS project:
The load-esm library performs the import operation outside the scope of the TypeScript compiler, avoiding the import being transpiled to require().
There are several methods to workaround this problem.
I found what was causing the issue for me on Bazzite. I had a keybind to change keyboard layout set to alt+shift (by default), and it prevented that keybind from being used anywhere else.
The keybind does not reside in the normal keyboard settings, instead you have to find it in gnome-tweaks (in my case it the app that launched gnome-tweaks was called "extra settings").
In there, go to "keyboard" -> "additional layout options".
There will be a setting "Switching to another layout", and if it is modified, it will be shown in bold. You have to unset it or set to a different keybind to make alt+shift work in other apps like VSCode. If you unset it, the default layout switch keys in linux is alt+space.
Unfortunately I don't think there is a way to both have layout switching and VSCode use alt+shift at the same time.
For screenshots of where to find this setting take a look at this - https://askubuntu.com/a/967493. My system is not on english so my screenshots would be confusing.

I’m not entirely sure this belongs as an answer here, but I did encounter the same “PermissionError” before I found the following workaround.
While submitting jobs from an HPC login node at my institution, I discovered the PermissionError came from a parent directory many levels higher than my working directory — one whose permissions I couldn’t modify. My workaround was to switch to a different login node and submit the exact same job.
This problem of the original login node throwing up PermissionError seems temporary and should be fixed once the HPC finds out about it.
This file structure comes from ratatui: since it's a framework, not just a library, it dictates the file/project structure to stick to (obviously, I understand that I can deviate from it, but not an expert enough to think that "I know better").
Ratatui maintainer here. You're smart enough to deviate. Feel free. My feelings won't be hurt.
Libs and Cli tools in the same crate can be a pain. In particular it's difficult to have dependencies which are just for the cli which you don't want to be included in the lib. You can feature flag them and make them optional, but this is suboptimal for cli tool installation using cargo (as it means that you need to specify feature flags all the time).
The best available approach (at the time of writing end of 2024) is to release two crates my-game and my-game-cli.
Does anyone know of any way to convert a simple GIF to XAML? E.G. A tool that would look at an image and create ellipses, rectangles, and paths based upon a GIF / JPG / bitmap? This reminds me of a time when I was working on a project that required transitioning a static logo from a JPG to vector format for better scalability and customization. The process was similar to what you're asking about—turning an image into shapes that can be manipulated in design software. While XAML conversions might be more niche, tools like Adobe Illustrator or Inkscape can convert raster images into vector graphics, which could then be adapted into XAML paths with some tweaking. It’s a fascinating intersection of design and development!
In ratatui 0.30.0 (coming early 2025), we'll introduce a ratatui-core crate, which should be more stable and see version bumps rarely. This should solve this for most situations.
There's quite a few places where this sort of thing has come up in widget libs. This particular problem is caused by the fact that >=23 really means the largest available version that matches >=24 (i.e. 24). It does not mean any version which is also compatible with all other versions that are in the dependency tree.
Solving this more generally - if a lib wants to support multiple versions like this (0.23 and 0.24), then it's best to add a feature flag per version. You'll see this in a few different crates when there's a major breaking change (e.g. axum springs to mind as one lib where this happens). This wouldn't generally be a good idea for Ratatui libs however as we've been happy to regularly release breaking releases (and hence bump semver to indicate that). As mentioned about that will change soon.
Depends on you use case, I have struggle too, because I work with highly inheritance architecture and it's incredibly annoying to implement all methods of interface to all children. (I'm creating event based simulation similar to Anylogic)
The only working solution I was thinking is creating python style architecture, where everything is map[string]interface{} and create classes and function in functional way to work with that interface.. and when thinking more about it this way probably fixes my rust struggles with same problem.
Since NeoForge 21.4.x items' models are searched in directory /assets/<mod_id>/items. So, I had to create two files in this directory for my two items respectively like this:
in classes, you have a few extra features that allow you to have more performance than the object method:
inheritance:
Each instance of Dog shares the same constructor and bark() method. It only references that to a certain place in the memory. BUT in the object method, you declare the method and variables within the loop all over again, reducing performance.
caching:
methods and everything you construct in classes is cached, no matter how many times you initialize the class (new Dog();) it will only declare for once and will be referred to the cached value or method, unless your class uses a dynamic value for the constructor. but in objects, you are redeclaring the methods 1000000 times. but it's declared once in class
these are the main concepts that classes are faster in this scenario
The easiest way to make this work is to render the TUI to stderr instead of stdout (see the backend methods which accept a writer e.g. https://docs.rs/ratatui/latest/ratatui/backend/struct.CrosstermBackend.html#method.new). The second easiest is to write explicitly to the tty device instead of stdin / stdout. E.g. open the /dev/tty file and use that as the writer. (Notably, the Termwiz backend uses the tty by default IIRC).
if you are rendering with ssr or ssg, the component in app would be server component .when we pass server component to client component the server component renders on server and along with placeholder in client component is sent to client where further rendering takes place.
if you are rendering with csr entire render process takes place on client
I got this problem when I started serving static files directly from nginx. It went away when I removed JS from being served by NGINX and send it to PHP.
The Livewire files are served via a dynamic route. These are not located in the folder structure in those specific paths. So it is better to let Laravel/Filament handle these files.
You can create a Setting without using transaction.on_commit. This ensures that if the main transaction fails, the entire transaction, including all records created in signals and within the save method of your model, is rolled back.
In 2024, you can use structuredClone, majorly for arrays and objects. It provides a deep clone of the given value.
For shallow copy you can use the above answer given by @xynon - https://stackoverflow.com/a/60460458/11410210, which I would suggest to use as per requirement.
