The definition @Lajos Arpad gave of Theta is completely wrong without the additional context that we are talking about average-time complexities.
Theta indeed means that its a tight bound, as he said. However, that does not mean it is an "average" bound. It means that Theta gives both an (asymptotic) upperbound and an (asymptotic) lowerbound. Basically, if $f(n)$ is the maximum number of elementary operations the algorithm does for an input of size n, then we say:
- $f(n) = O(g(n))$ if there is some constant $C$ such that $f(n) \leq C \dot g(n)$.
- $f(n) = \Theta(g(n))$ if both $f(n) = O(g(n))$ and $g(n) = O(f(n))$.
For instance, an algorithm that does something like:
def f(n):
for i in range(n):
for j in range(n):
#something
for k in range(n):
#something else
where `something` takes between $1$ and $3$ operations and `something else$ takes between $1$ and $2$ operations will take in total at most $2n^2 + 3 n$ operation, which is smaller than $5 n^2$, i.e $f(n) = O(n^2)$.
It is also true that $f(n) = O(n^3)$.
Since we also have $n^2 = O(f(n))$, because $n^2 \leq n^2 + n$, we must have $f(n) = \Theta(n^2)$, i.e the algorithm described by $f$ takes asymptotically exactly a constant multiple of $n^2$ steps to complete its task.
HOWEVER, if we consider instead average-time complexities (instead of worst-case complexities, as above) then the above example is true. The corresponding definitions are the same but with $f(n)$ being defined as the average number of operations the algorithm does for an input of size $n$.
recently we faced same issue , our case was related to network communication issue between nodes on UDP protocol , tcp connections we allowed ping and all required ports was allowed , but UDP connection was failing we fixed the network issue and solved it , before retrying you need to clear cluster node to ensure that you testing without issues
Since I just deployed local_doh and ran into the exact same problem (FF Android certificate exceptions reset on every app cold-start/reboot) you need to configure dnscrypt to send the whole certificate chain including all intermediates, and root (in this order)
Good news is you don't even need Let's Encrypt and can just roll your own CA (if you don't mind installing it on your clients) so this should theoretically even work on a router running dnscrypt (like OpenWrt)
This was tested with OpenSSL v3 as we are using some “advanced” arguments (namely addext and copy_extensions) which may or may not be available in legacy (1.0) versions! If you are stuck on a legacy version, generate it somewhere else and copy the certificates and keys over.
Configure dnscrypt to use your full.crt as cert_file = /path/to/full.crt
Open FF on Android and go to the DoH endpoint e.g. https://server.domain.local:3000/dns-query which should now show an encrypted connection w/o any warnings.
If you run LE everything should work and you are done, if not open the URL on Desktop and make sure dnscrypt is actually sending the full certificate chain including all intermidate!
If you did roll your own CA dnscrypt will log a unknown certificate authority denoting the client not trusting the CA used to sign the DoH certificate
To fix this take the ca.crt from #1, copy it to your device, and install it in the Android certificate store: Settings > Security > Install Certificate > Install CA certificate
Which will bring up a scary screen displaying something about your data not being private yada yada and requesting biometric authentication since you are messing with the CA store.
Finally (re)open Firefox, go to Settings > About Firefox and tap on the logo to unlock the Secret Settings menu, go back to Secret Settings and enable Use 3rd Party CA certificates and completely (force) close FF
Now go back to #7, if something doesn't work reboot Android
Apparently the culprit was provideClientHydration() in app.config.ts.
Regardless being provided with the correct data by the API & enabling no-cache, it will be overridden and the service.ts file will return a stale data.
I hope someone more knowledgeable can improve my answer to better explain it if needed.
When you use BlocProvider , it ctreates its own context. The context inside button is reffering to the TempScreen.
BlocProvider creates a new subtree, and the outer context does not contain the new provider. So context.read<TempScreenCubit>() is using the wrong BuildContext.
The correct context is the one inside the BlocProvider subtree, not the one from TempScreen’s build method.
My goal is to load transactions for only those customers which is present in Input View and do some processing on them later.
The current implementation is:
1. Hdfs has data for customers with columns (cust_id, date, uuid)
So , first I read this data and create input view on this one.
2. Now later in the pipeline I have create a view from transactions table of DB having schema (transaction_id, customer_id, date, transaction_amt, tran_type, current_amt).
3. At this point I now have both views with me input and transactions view. Then i am running SPARK SQL on them as "Select i.cust_id, t.transaction_id, t.transaction_amt, t.tran_type from transactions t join input i on i.cust_id=t.customer_id && i.date= t.date"
Now what happens here is that Spark will load all the data from transactions table to create view which is not efficient. I want to achieve some filter push down in RDBMS also like Spark does for Hdfs.
If you receive it from a non-malleable source then you must process it. Whereas if you are creating your own source use UTF-8 as a wide variety of systems can read it . I would not suggest adding further non-UTF-8 sources to the world.
There is already a fire here as other comments make clear. Don't add gas?
I am facing a problem with reqSecDefOptParams. since reqSecDefOptParams provides data grouped by ticker->exchange->tradingClass->(list of expirations, list of strikes). When I select a expiry that is suitable for my strategy and filter a suitanble strike, that chosen strike price may not be available for the chosen expiry. Since all expirations and strikes are bundled there is no way to findout which strikes are available for which expiry.
is there a way to group strikes available for each expiry?
My guess is the main bottleneck is writing to IO. The way to speed things up is buffering frames correctly if you are not already. Instead of printing line by line, generate the whole frame/screen and write it at once. Second thing is to use asynchronously generate the frame and write to IO, or use different threads/processes for each. However, It's hard to see what's going wrong without a minimal code example.
that's fun to see a lot of upvoted answers, which relies on process.env.SOMETHING
that would not work on every-environment, especially on production (where you have a static build served by nginx for example)
I understand you're having trouble with the component used to add a movie or anime on the HiAnime website. Since the component is a core part of the user interface for content contribution or personal list management, its malfunction can be very frustrating.
Here is a step-by-step troubleshooting solution, keeping the HiAnime context and the official URL in mind:
1. Basic Troubleshooting Steps
Before assuming a technical bug, try these common fixes which resolve most front-end issues:
Refresh the Page: A simple browser refresh (F5 or Ctrl+R) often fixes temporary loading issues.
Clear Browser Cache and Cookies: Your browser might be using an outdated version of the HiAnime component code.
Try a Different Browser: Test the component on another browser (e.g., Chrome, Firefox, Edge) to rule out browser-specific extension conflicts.
Log Out and Log In Again: If the component is tied to your account permissions (which is common for user-submitted content), logging out of your HiAnime account and logging back in can reset session data.
2. Identify the Exact Component Function
To find a permanent solution, we need to know exactly how the component is failing:
ScenarioWhat to CheckComponent doesn't appearIs there a missing button (e.g., "Add New Title" or "Contribute")? Ensure you are logged into your HiAnime account.Component appears but fails on submitDoes it give an error message (e.g., "API Error," "Missing Field," or "Database Connection Failed")? Take a screenshot if possible.Component fields don't load/interactDo dropdown menus, search fields, or genre selectors work? This suggests a JavaScript loading issue on the HiAnime page.
3. HiAnime-Specific Recommendation (Reporting the Bug)
If the basic steps don't work, the issue is likely a bug in the website's code and needs to be reported to the development team for a fix.
Report the Bug: Look for a "Contact Us," "Report a Bug," or "Support" link on the HiAnime site.
Provide Details: When reporting, be sure to include:
Your username (if applicable).
The exact sequence of steps that led to the component failing.
A screenshot of the error message or the broken component.
Your operating system and browser version (e.g., Windows 10, Chrome v120).
4. Direct Link to HiAnime
While waiting for a fix, always use the correct URL to ensure you are on the official site:
I'm not entirely sure what you're asking. Homebrew doesn't use Hashicorp. Are you saying, you used Homebrew to install Hashicorp Vault and you don't know where it put the files?
Windows has the option to delete previous options of the operating system by navigating to Settings > System > Storage > Temporary files and select "Previous version of Windows" or you can use disc cleanup tools
And the code runs properly with no build errors, or console errors or warnings. I don't know what causes this settings being turned on, to not function.
Well, your contributions do show up from any branch, not just main. If you're not seeing green boxes, check if the commits are made with the email linked to your GitHub account (that happened to me). 2) the repository isn't a fork (contributions to forks don't count unless merged upstream) and 3) commits are within the last year.
And customize this, However, it should send the request in the same format that the server requires. Finally, add ref to script generated in razor page same as:
Your question isn’t clear. What exactly do you want the function to do, and what does ‘stop the one before it’ mean? Also show how you’re calling these functions. Without that, it’s hard to give a useful answer.
On my case, it was because I was testing my Android app with a different package name, example: the original and released app is: com.orgames.mygamename but I was testing a local build using com.orgames.mygamenamecustomized. Going back to the original package name stopped the activity is cancelled by the user error.
Add Source > Media Source > Name it w.e
(This will then open its properties window)
Uncheck "Local File"
Leave rest as-is
Enter RTSP Address in "Input"
(ex: RTSP://Username:[email protected]/stream1)
note: sometimes the port number may be required which is 554 default
(ex: RSTP://Username:[email protected]:554/stream1)
Save Settings and close properties window, Everything should work!
Then click "Start Virtual Camera" in the OBS Main Window
not knowing how maxLength is involved in your compare_fingerprints(): what about pre-selecting a range of fingerprint fullfilling e.g. +/- 10% of audio llength and thereby reducing the number of comparisons?
it apears to be the essencial thing to reduce loop count, as 10mio is really >many< for all scripting languages.
Second thought is, that a fingerprint doesn't appear to be a first choice for similarity comparisons as it has to be regarded as a more or less "random" id. So: what does your compare func really do?
Even if it doesn't do much but compare the length and check for equality of fprints, its a lot of overhead just to handle the 4 (!!!) parameters 10mio times. So, can you rethink the concept of your compare func?
deno is massively caring itself for handling stdout, stdin and stderr. you cannot tell, what is does, when stdout is closed and gives an error upon usage.
and what's maybe of even more inportance: you code above does not close the stdout and stderr, but stdin and whatever input #2 may be.
to close stdout, you need to `exec 1>&-´ instead of `exec <&-´ ... is that a typo in your question or did you indeed close input stream instead of output ?
Welp looks like ChatGPT comes to the rescue again:
None of the instructions I've looked at told my about enabling the virtual hosts in /opt/lampp/etc/httpd.conf
I've had this same problem, where System.out.println()s from my Cucumber tests didn't show up in the output. It turned out that the reason was because my Docker / Colima configuration was messed up, and Cucumber was having trouble spinning up a Docker image to run the Cucumber tests with. So I dumped my images and reconstructed a clean Docker and Colima. Then, the Cucumber tests proceeded without problems, and I saw the System.out.printlns in the log.
Have you never heard of thumbnails? 1/8th or 1/16th would be much better choices for downscaling an image on the fly. BTW you don't specify what format they are in. Nothing can beat having the precomputed thumbnails of full HD images available to preview download as JPEGs.
you should have thumbnails avail for the "usual" pages (knowing, its a "view" only and linking to the large full blown images only upon clicking the image or a download button.
an automatic solution to reduce the size would request the following criteria to be somehow decidable by the server process:
does the user WANT to have the large variant?
what's the local name of a reduced size image?
Since there usualy is no way for the server to answer them, there needs to be something answering them. the answer can be made only upon available infos e.g.
what browser requests it
link provides direct access to the large version
etc.
there are tools avail to generate both at once: thumbnailing the images to HAVE a smaller version and also generating "view" pages linking to the generated thumbnail as well as linking to the full detailed version of them
To serve them, that's a pretty open-ended question. However you do it, I'd recommend generating the small image only if it's requested, but then make sure you keep it around so you can provide it on demand, without having to generate it again.
I'm concerned about the case where the intl extension is not installed because (a) there may be some sites where it's difficult for the user to install/enable it and (b) I want to make it as easy as possible to use the application. So if somebody's wanting to use a genuine language xy, then I want to know whether it's possible, or whether I should fall back to their next, genuine, choice. As things stand, Windows will just tell me that, yes, it's managed to set the locale to xy, when in fact it hasn't.
You should never trust external data without validation. So the Accept-Language header may be faked to anything that could harm your application. So verify always before use.
Why are you concerned of the Intl extension not to be installed? Make it a dependency.
Thanks for pointing out the option to uncheck, but alas, after unchecking the Enable JavaScript/Typescript Language Service Prototype option, you can no longer right-click and Find All References - doing so results in "Search found no results".
How to Intercept Network Traffic in a Chrome Extension Using chrome.debugger API
Overview
The chrome.debugger API allows Chrome extensions to interact with the Chrome DevTools Protocol (CDP), enabling network traffic interception. This is useful for monitoring, logging, or modifying network requests and responses in real-time.
Step-by-Step Tutorial
1. Manifest Permissions
Ensure your manifest.json includes the necessary permissions:
In your service worker (service-worker.js), attach the debugger to the active tab:
async function attachDebugger(tab) {
if (!tab || !tab.id) return;
if (!tab.url.startsWith("http")) {
console.error("Debugger can only be attached to HTTP/HTTPS pages.");
return;
}
const debuggee_id = { tabId: tab.id };
try {
await chrome.debugger.detach(debuggee_id);
} catch (e) {
// Ignore if not attached
}
try {
await chrome.debugger.attach(debuggee_id, "1.3"); // https://chromedevtools.github.io/devtools-protocol/
await chrome.debugger.sendCommand(debuggee_id, "Network.enable", {});
console.log("Network interception enabled.");
} catch (error) {
console.error("Failed to attach debugger:", error);
}
} // Google's boilerplates: https://github.com/GoogleChrome/chrome-extensions-samples/blob/main/api-samples/
// usage: Attach on action click
chrome.action.onClicked.addListener(async (tab) => {
await attachDebugger(tab);
});
3. Listen for Network Events
Set up event listeners for network events:
const pending_requests = new Map();
chrome.debugger.onEvent.addListener(function (source, method, params) {
if (method === "Network.responseReceived") {
// Store request ID for later retrieval
pending_requests.set(params.requestId, params.response.url);
}
if (method === "Network.loadingFinished") {
const request_id = params.requestId;
const url = pending_requests.get(request_id);
if (!url) return;
pending_requests.delete(request_id);
chrome.debugger.sendCommand(
source,
"Network.getResponseBody",
{ requestId: request_id },
function (result) {
if (chrome.runtime.lastError) {
console.error(
`Failed to get response body: ${chrome.runtime.lastError.message}`
);
return;
}
if (result && result.body) {
const body = result.base64Encoded ? atob(result.body) : result.body;
console.log(`Response from ${url}:`, body);
// Process the response body here
}
}
);
}
});
Running the Extension
Create a new directory for your extension.
Save the manifest.json and service-worker.js files as shown above.
Load the directory as an unpacked extension in Chrome:
Click the extension's action button (puzzle piece icon) to attach the debugger.
Open the developer console (F12) to see logged network responses.
Interact with the page to trigger network requests and observe the logs.
Handling the "{"code":-32000,"message":"No resource with given identifier found"}" Error
This error stems from Network.getResponseBody and is symptomatic of the following common causes:
Timing Issues: Network.enable must be called before requests are made. If called after, existing request IDs are invalid.
Buffer Overflow: Chrome's Network domain has memory limits (~10MB per resource, ~100MB total). Old responses are discarded FIFO.
State Reset: Network.enable resets the domain state, invalidating previous IDs.
Incomplete Response: Calling getResponseBody before loadingFinished.
Mitigation:
Best to attach the debugger only once: Implement debugger attachment through a single, controlled mechanism (e.g., via chrome.action.onClicked) to prevent multiple or conflicting Network.enable commands. Each Network.enable resets the Network domain state, clearing buffers and invalidating existing request IDs. Calling it redundantly or out of sequence can cause state resets mid-session, leading to the "No resource" error.
API error handling: CDP APIs do not throw errors; instead, failures are indicated by setting chrome.runtime.lastError
Adjust buffer sizes for large responses: If dealing with large response bodies, configure Network.enable with increased limits, e.g., Network.enable({ maxTotalBufferSize: 200000000, maxResourceBufferSize: 50000000 }), to prevent FIFO eviction of response data before retrieval.
I'm trying to set the locale based on the user's browser preferences from the Accept-Language header. If the first preference doesn't work, because the locale is not available, I want to fall back to the next one. So I need to know whether setlocale() genuinely succeeded. If the intl extension is installed then I can test as above, but if not?
Check your $http function parameters - in my case, I was using params instead of data, and that's why it was giving me such error. I was also writing the function a little bit differently.
Yes, but not in the form of a simple built-in mapping table. Windows uses its own locale naming scheme and PHP does not translate between BCP47 tags like en-US and Windows names like English_United States. To get a proper mapping you need to query what Windows itself exposes.
You can do that with the intl extension. The ResourceBundle for the root locale contains the Windows locale identifiers and their corresponding BCP47 tags. With that data you can build your own lookup table at runtime. Another option is to call Locale::canonicalize on the BCP47 tag and then use Locale::getDisplayLanguage and Locale::getDisplayRegion to compose a Windows style name. Both methods give you a consistent way to turn something like en-US into the Windows name that setlocale will actually understand.
Outside PHP the official source for the mapping is the list of Windows locale identifiers published by Microsoft. That list includes the Windows locale names, the numeric identifiers, and the matching BCP47 tags. If you need a complete and static table this document is the closest thing to an authoritative reference.
async function handleRequest(request, env) {
const url = new URL(request.url);
// --- 1. Dynamic Content: Route /php traffic via Cloudflare Tunnel ---
if (url.pathname.startsWith('/php')) {
// --- Massaging Steps for Tunnel Routing ---
// 1. Path Rewriting: Strip the leading '/php' so Tomcat sees the root path (e.g., /login instead of /phpy/login).
const originalPathname = url.pathname;
url.pathname = originalPathname.replace('/php', '');
// 2. Origin Host Assignment: Set the internal hostname for the fetch request.
// This hostname is tied to the Cloudflare Tunnel in your Zero Trust configuration.
url.hostname = '999.999.999.999';
url.port = '9999';
url.protocol = 'http:';
// 3. Request Reconstruction: Clone the original request to apply the new URL and host headers.
const newRequest = new Request(url, request);
// 4. Host Header Override: Crucial for Tunnel. Explicitly set the Host header
// to the internal hostname so Tomcat knows which virtual host to serve.
newRequest.headers.set('Host', '999.999.999.999');
// Final fetch request uses the rebuilt request object, sending it securely
// through the Cloudflare edge to your connected Tunnel.
return fetch(newRequest);
}
// --- 2. Static Content: Serve all other traffic directly from R2 ---
else {
//usual stuff here...
//...
//...
//...
//...
//...
}
}
// Bind the handler function to the 'fetch' event listener
export default {
fetch: handleRequest,
};
The problem is that DA errors are considered as "internal errors" by the apex error handling function, and there is no handle that passes a message to the users. To fix this, you must choose an exception number, for example -20999, and create a handle in the internal section of the function. When this is done you can pass your message with raise_application_error(-20999,<message>);
The developer of the system found out that they weren't using the correct python functions to support user-assigned identities. They just tested with VM identity, not a user-assigned one.
i think i not use cloudflare for reverse proxy similar to nginx. it doesn't seem like this is a common use case. If I got stuck at a showstopper bug, I would immediately scrap using cloudflare for this purpose. I think 99% of people use cloudflare as simple CDN and forcing it to use PHP app is not good idea... hmm
On Windows the C runtime that PHP uses for locale handling does not validate locale names against any real list. It only checks the general pattern of the string. As long as the part before the dot is short enough, the call succeeds even if that locale does not exist at all.
When this happens Windows simply keeps the system default locale for every actual formatting function. That is why date output stays in English even though PHP reports that the locale was set to the exact string you passed in.
If you try a string that does not match the expected pattern, for example something with more than three letters before the dot, the call fails and PHP returns false. That is the only point where you notice that Windows rejected it.
To get real locale changes on Windows you need to use the Windows specific locale names such as English_United States with the correct code page. Only those names cause Windows to switch to a real locale and affect formatting output.
wmctrl does not move a zenity window in a bash script unless it is first deactivated. By deactivated and then activated zenity you can change the position of the window. For example add the following lines before the zenity command (z-name is the name of the zenity window):
(
sleep 0,5
wmctrl -a Firefox
wmctrl -a z-name
wmctrl -r z-name -e 0,2000,400,-1,-1
) &
In the string you are sending to the printer, replace "_" with "_5F"
If "_" is specified as the hexidecimal escape character, as the other poster mentioned, then the next two characters will specify the ascii code of the character that will print. "5F" is the ascii code of the underscore, so if you send "_5F", it will print the underscore character.
In this situation I would host the PHP backend on a different cloud like Azure or AWS.
In PHP you can get stuff from r2 buckets even if your server is running outside of the Cloudflare ecosystem. https://developers.cloudflare.com/r2/examples/aws/aws-sdk-php/
vision: r2 bucket as cdn for hosting static files, and then login/session stuff routed to externally hosted php app.
I wasn't sure if this is a common use case, as 99% of the examples and aibot answers are referring to using cloudflare's internally provided serverless workers, and rarely is there any mention of use of one's own app servers.
Though I tried much of the above, I could only sovle the problem by simply renaming the Java project directory in Windows File Explorer. Then I opened the newly named directory in VS Code and everything worked fine.
