If I VPN to another country with a free dummy account and save offline songs, can I then use my regular premium account and somehow point to the cache so those foreign songs are not greyed out on my regular account, since they’re still on the same computer? I realize this might require some trickery/coding, just wondering in theory.

applications – How to play CACHE Audio files ? How do I convert them to mp3 files?
I have a music streaming app that can download music. I checked the directory of the app in Internal Storage. It has got audio files for the songs I had downloaded but in CACHE format.
I would like to know how can I play those CACHE files on a different device say my PC? How can I convert CACHE audio to mp3 ?
I have tried changing the extension to mp3 (This method presently works with .xoht files of music) but here it make the audio corrupted.
I searched the net for conversion of CACHE to mp3 but have got a result on a site that converting CACHE files is not possible. SRC: https://www.lifewire.com/cache-file-2620119
Cache consistency in uniprocessor system
In a uniprocessor system, can we have a Cache consistency problem? For sure, it exists in a multiprocessor system. But I wonder if it exists in a uniprocessor system and in which scenario.
use multiply cache service ????
on share environment someone need redis another one need memcache,
is it stable to run both of them on server ?… | Read the rest of https://www.webhostingtalk.com/showthread.php?t=1843093&goto=newpost
8 – Clearing Cache related to user data
Drupal’s cache system is a complete nightmare causing all sorts of issues with my user sessions. To provide a couple examples
- Our navigation header block contains a link that takes users to a different link based on their gender. If they are male they go to this site, if they are female they go to that site. If I login as a male and then logout, then login as a female, the link is still linking to the male link. Once I clear the cache, this works as expected.
- We have an EventSubscriber on Requests using the EventSubscriberInterface that will redirect a user based on a custom field
field_verified
. If a user’s field is marked as false, the event subscriber redirects them to a verification page. If I login with a verified user and then logout and create a new user (therefore not verified) the EventSubscriber never gets executed, so the user isn’t redirected properly. Once I clear the cache, this works perfectly fine.
I have an endless list of situations like this where user data is persisted through different sessions and is only fixed by clearing the cache. I don’t want to have to flush ALL the cache everytime a user logs in or creates an account as this is a performance issue.
How can I clear cache related to just the user objects and sessions?
How do I reduce the FS-CACHE cache partition safely?
I have an NFS mount cached using FS-CACHE and I want to reduce the size of the cache partition. I don’t mind resetting the cache, so is it fine if I reformat/clear the partition before resizing it? Or is there a special command to reduce the cache size?
networking – Wifi Hotspot – Getting 504 Timeout (and CORS) when cache is not disabled
I have an android phone that I’m using for wifi hotspot to which I connect my laptop to. There is generally no problem with it however sometimes content just doesn’t load.
I tried checking the Network DevTools to see what the problems are and figured out what requests were causing it. The causes were requests to a different domain and they are in “(pending)” status for a long time and eventually turning “CORS error missing Allow Origin”. Upon examining further (using a different network) the responses properly have the needed headers and the requests properly have the origin matching the allow orgin header. When I tried checking again (with the mobile network), the response it receives is the 504 Gateway Timeout (which doesn’t have the allow origin header) so Network DevTools i think treated it as CORS.
Now the thing is, when I try to use the “Disable Caching” feature of devtools everything works fine (except that caching is disabled so it eats quite more). So I am not sure what would be the cause of the 504 timeouts and if possible find a solution for it.
I’ve also noticed that I can load the requested url on a different tab and then that specific resource would load fine on the main site I was visiting but doing this for every resource is pretty tedious and doesn’t really fix the issue. I have also tried using a different android device with the same SIM but it still had the same results.
As a band-aid, I was thinking of disabling cache for the specific domains but I am still unsure of how I will do it.

c++ – Is array loaded in cache completely, does it pollute cache?
In regards to cache usage and supposing 80/20 use of objects, can the objects be laid out (option 1) in an array without polluting cache with the rest of its indices when called; or (option 2) to prevent cache pollution, each object must be defined separately?
I have an enum EFoo
and want to use it as a key to static objects Foo
(with size of 128 bytes). If they’re the same, option 1 is better because it doesn’t require maintaining an additional switch list.
Storage:
// FooData.inl
#include Foo.h
// option 1: stored as array
static constexpr Foos(256) {
/* A */ {...},
/* B */ {...},
}
// option 2: stored as separate
namespace Foos {
static constexpr A { ... };
...
}
Usage:
// Keys.h
enum class EFoo : uint8 { A, B, ... }
// Foo.h
struct Foo { ... void operator= (EFoo Key); }
// Foo.cpp
#include Foo.h
#include FooData.inl
void Foo::operator= (EFoo Key) {
// option 1: read from array
*this = Foos((uint8)Key);
// option 2: read from separate
switch (Key) {
case EFoo::A: *this = Foos::A; ...
}
}
proxy – How do browsers cache PAC files?
How do browsers and other applications cache PAC files? If I’m serving a PAC file and update the configuration (e.g. add or remove a domain that should go through the proxy), when will different browsers recognize the updated configuration? Is there anything I can do on the PAC file server to flush the cache?
How long do PAC files stay in a browser cache? What will trigger the cache to be cleared?
I have found this https://support.microsoft.com/en-us/topic/how-to-disable-automatic-proxy-caching-in-internet-explorer-92735c9c-8a26-d0d8-7f8a-1b46595cbaba for IE, but not finding any information for Chrome/Firefox/Edge
