It will clear the caches of all your apps. It's the same data you can clear by tapping the Clear cache button on the App info page for each app in Application Manager, except this clears the cache for all apps at once. Cached data generally consists of the app's frequently or recently accessed data, information about the app's current state, and login credentials. Pretty much the only irreplaceable data that's ever stored in a cache is search history and records of recently accessed items (though many apps store this kind of info in app data rather than the cache, and the cache is never used for logs or records that users are expected to want to keep, such as call history in the phone app). Worried I'm gonna lose something I need. Unless it's important to you not to lose search/view histories on apps where the developer didn't think they would be important to keep, no, you won't lose anything you need because all the data in the cache is easily replaceable. Some apps might run a little slower temporarily as they re-access data that was previously cached (and presumably, put it back in their cache), start on the default screen rather than the most recent one you were using, prompt you for credentials instead of logging in automatically (just the first time), and things of a similar nature. Now, the question is whether you actually have a reason to do this. The two main reasons I can think of is if you're out of storage space and need to clear some quickly without uninstalling apps or sifting through your files to see what you can delete, or if your phone has been having strange inexplicable quirks that you suspect might be caused by some misbehaving apps.

GitLab has some docs on how to speed up builds, and one of the suggestions does involve caching runner images. https://docs.gitlab.com/runner/configuration/speed_up_job_execution.html#use-a-proxy-for-containers Use a proxy for containers You can speed up the time it takes to download Docker images by using: The GitLab Dependency Proxy or A mirror of the DockerHub Registry Other open source solutions There are other non-container related suggestions too, as well as information on how to use these up at that link. You can also host your own runners, in which case you can run them on docker or just centos, etc. I assume, in that case, that you could already have the images available on the runner node to avoid new pulls. We run ours in kubernetes and are looking at harbor as an option to speed these things up too, but we haven't tested it yet. I imagine self-hosted k8s and harbor would be similar to GitLab using its own dependency proxy solution.

Django should not be responsible for the installation of statistic heds. The server will be responsible for this, like Nginx or Apache.In a local car, your style serves the django itself, but as it says in the manuale, it's highly inefficient in terms of productivity. To be clear, the picture looks like that. The request - state Nginx defines the type of request - if the statistic is, it shall itself be submitted, if it does not give it to the standing annex - t.k Django communicates with the wsgi protocol serves the django itself, for example uWSGI(uWSGI wsgi protocol), the request shall be submitted to django itself. The answer goes up the chain. Now it becomes clear why this is so ineffective and why django should not do so. Read Django documentation https://docs.djangoproject.com/en/1.9/howto/static-files/ Determine who serves the statistic on the combat server and read in this direction. For example https://serversforhackers.com/nginx-caching/

In fact, you have a few options.It's an approach when you keep something in the database, and at the same time you're sending something to update your picture.The second option is to implement Father Observer. So that your database would inform all subscribers of the changes.For example, if you use the room and LiveData, that's what the solutions are. How to do this, there are many options, depending on the project and the tools you use.

Try adding to the block server another location. location ~* ^.+\.(jpg|jpeg|gif|png|ico|html|css|zip|tgz|gz|js)$ { root /var/www/html/public; #ваш путь к статическим файлам access_log off; expires 30d; }

The main challenge is to maximize the processor ' s downloading and minimization of memorial data.Several levels of kash differ in access rates primarily. Level cashing makes it possible to optimize the downloading of data from the core memory and to keep the processor in the right hand. There's a good warehouse analogy - a store - a refrigerator - a plate. The details of the cash are described at Tannenbaum.

Probably. https://laravel.com/docs/5.4/installation#configuration :Directories within the storage and the bootstrap/cache directories should be writable by your web server or Laravel will not run.What's the emergency question for a server like this without a record? How did the app get there?

The question is a little broad, but let's go.I imagine you've read it. https://docs.microsoft.com/en-us/dotnet/api/system.runtime.caching.memorycache?view=net-6.0&WT.mc_id=DOP-MVP-5002397 . At least that's what the programmer does when he sees something new he doesn't know and wants to know more. I'm not gonna talk about what's already there. It doesn't seem to be the focus.Cache is one of the most important and most used strategies for making data accessible faster. Cache is simpler than people imagine. You do a calculation and save on a variable is cached. You want simpler than that? Of course, here we are talking about a somewhat more sophisticated mechanism.Cache is extremely complicated as it goes out of the trivial, especially when it needs https://pt.stackoverflow.com/q/356320/101 . But cache is just a way to deliver information in a faster way than the traditional way, no matter how much. An example would be https://pt.stackoverflow.com/q/104014/101 which is the basic design pattern used in much of the cache mechanisms.You can have multiple cache levels in the application and surrounding it. It may have something that is part of your application or that is done by third parties in infrastructure that you use directly or indirectly, something hardware or software. To choose which ones to use and which ones are exaggerated is an art. Some of you do not choose, exist and good. Since it is very complicated to make certain caches it is better to use some ready mechanism in many cases.So the question is lower, that's when you use the cache. When it is necessary then MemoryCache must be your choice (but may have other cache levels outside your application). It will be correct, has the form that is probably more efficient, competition controls and mainly already https://docs.microsoft.com/en-us/dotnet/api/system.runtime.caching.cacheitempolicy?view=net-6.0&WT.mc_id=DOP-MVP-5002397 . And one of the most important things is having one https://docs.microsoft.com/en-us/dotnet/api/system.runtime.caching.changemonitor?view=net-6.0&WT.mc_id=DOP-MVP-5002397 , which is one of the most consistent disability that exists (with advantages and disadvantages).The actual example depends on the situation, so it is very difficult to put an example. Anyway no matter the mechanism, it is important to understand the entire software development process to absorb on the need for cache. You don't have a magic answer unless you should use it when you need more performance and a test show that the cache resolves partial or totally. There is no situation that you can say you should always use or should never use, even because the very same problem can change if the volume changes.There are problems that caching helps little or nothing or hinders. If you have rare access to the same data the cache is just a stun. Only the repetition pattern of access to the same data several times is that gives you clear advantage.Already https://pt.stackoverflow.com/q/139932/101 , remains valid here.

This response is based on my personal experience, in what I learned in practice, and includes conceptual inferences from this experience. See detailed examples point to point in https://pt.stackoverflow.com/a/358150 .Before we talk about the disability of the cache, we need to define the cache itself. In a simplified way, cache is a quick access copy to something. Cache is used to avoid repeating some costly operation, and the costly concept depends on the context. For example, your CPU caches data to avoid repeated memory readings, which would be slow about reading from the cache. On another scale, your browser caches the accessed content, to avoid repeated HTTP requests to the same features as you navigate.If on the one hand the cache streamlines access to the data, on the other hand it is a copy that tends to be defased. And there comes the dilemma of invalidation: when consider that something cached needs to be updated? And, worse, the invalidation of such data leads to the invalidation of other data too? And the disability of that second level invalidates what?It must have already given to realize that the problem is recursive – of course not always, but it has a lot of potential to be. So the big problem is to decide when to stop. This generally depends on the data stored, its structure, the cost of pre-processing these data before cache storage, the type of cache used and the available resources. That is, there is no universal solution. The higher the level of the cache – in order to contain more structured and interrelated data –, the more it needs to be "tuned" manually.There is also the question of the frequency or disability trigger. One can use a similar treatment to that of Garbage Collection in programming languages, in which the data is marked as invalid but is only cleaned (in the case of a cache, updated) at times of higher availability of processing, or at the first need for use of the updated value. Another path is trigger-based treatment, similar to what exists in SQL. Some event in the application determines that the cache should be updated and triggers the process.That's where I've always interpreted that quote. There are probably more reasons. I expect a more canonical response from another user.

A form is via file .htaccess, adding the code:<filesMatch "nome_da_imagem\.(jpg|png)$"> FileETag None <ifModule mod_headers.c> Header unset ETag Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate" Header set Pragma "no-cache" Header set Expires "Wed, 11 Jan 1984 05:00:00 GMT" </ifModule> </filesMatch> It will avoid file cache jpg and png with a fixed name. If you just want jpg, just change the regex to:"nome_da_imagem\.jpg$" If you want to avoid cache of any file jpg:"\.jpg$" Testing on Chrome using ChromeCacheView (CCV) application:First I will clear the Chrome cache and open the CCV. See that it's empty: I will open a page that contains only one image 1.jpg and update the CCV window: Note that cached multiple files (.js, .html etc.) but did not cache the image 1.jpg on the page.Now I will remove the code from .htaccess, clear the Chrome cache and reopen the page. When updating the CCV window, this time the image appears cached (1.jpg

In the brower, among other storage modes there is the localstorage that can be accessed via window.localstorageFor example inside the function you showed would just call the function window.localstorage.setItem(‘menssagem’, JSON.stringify(menssagem)) that your object will be persisted.I hope I helped

One of Python's philosophies is to facilitate the life of the programmerYou're responding. This is the opposite of what you're worried about. Perhaps it is a question of interpretation of the text. At least I can't imagine how the lack of optimization is a hamper for the programmer. I even understand the desire, but this doesn't hit Python's philosophy. Everyone can try to interpret the text as they please, but most people know that ease and optimization are different things.Whoever wants performance, efficiency, zero cost abstraction, these things are C++. C, Rust too, of course. Python never had these things as a basis to decide anything to do. If performance is desired to choose another language. Look how easy.However, did you test C++? And did you do it properly? testing is complicated. I don't guarantee he's optimized there. It is possible, and even probable, but without testing I do not guarantee. And if it is to optimize even this should be cost near zero because all tie is useless and just do x = 1 and nothing else, kills all loop, or not because then the variable is not used. Actually this code doesn't even make sense. Even the way of measuring is not the most appropriate.But in the end it is a matter of no one having decided to do optimization. Maybe because I could let the compilation slower, or for another reason. Maybe someone still does it, might you open one issue and someone does, it may be that you wanted to do and deliver to review of the community and the improvement is applied.

Doing a little research I found a solution that can serve you.Instead of doing a search in your cache, you can store the search using your url as key the first time you ask for it, and the second time it does the same search, you return the data by searching for the url in Cache.// Primeiro ele pega o url da requisição $url = request()->url(); // Depois os parametros de query da requisição $queryParams = request()->query(); // Ordena os parametros ksort($queryParams); // E torna em string os parametros ordenados $queryString = http_build_query($queryParams); // Monta o url completo junto com os parametros $fullUrl = "{$url}?{$queryString}"; // Encripta o url em sha1 para facilitar o armazenamento $rememberKey = sha1($fullUrl); // Em seguida faz Cache e depois retorna o valor armazenado. return Cache::rememberForever($rememberKey, function () use ($data) { return $data; }); In the original post, it stored results from a pagination. As you want to search for the title and description, you can ride your route like this:Route::get('/path/{titulo?}/{descricao?}', 'Controller@index'); There are other options for you as well as https://laravel.com/docs/5.6/scout , but I believe that it does not cover your need but it is worth taking a look.Answer based on this https://laravel-news.com/cache-query-params .

Seeing the graphs presented, I think you misinterpreted the problem.I have not seen CPU consumption as the problem, because this information is not shown. The amount of % you are seeing is not CPU, but it is time spent running that method. The cause can be several things (including CPU).In your specific case, the C3P0 seems to be taking time to get a connection with the database. The connection pool serves to streamline this, as the C3P0 keeps some connections always open and when the application calls for a connection, it already has a ready to use. However, if this step is taking, it is possible that the current pool is too small (in its current configuration, it is as 5) and it is needing to open new connections with the database. Opening a new connection with the database is something heavier, which would explain your problem.Another explanation is you have reached the maximum number of connections, which currently you have set up as 20. When this occurs, the system needs to wait to use an open connection, which would also explain the delay.The above two cases can be monitored on the server or directly in the database, accompanying the amount of open connections.To improve, you can increase the minimum or maximum pool of connections depending on your problem. Try a number greater than 5 for the minimum, for example. The exact number I can't tell you what it can be because it depends a lot on your application and the server.If you notice that this problem is more serious at specific times (as at dawn) check also if there is no heavy routine being round in the database during the schedule. Maybe this can affect the opening time of a new connection.

Hi, Horatio.It is not exactly plugin to be installed. The rules that influence PageSpeed are well explained on the WebPageTest websites. Org and GTMetrix.In your case, the .HTAACESS file should solve. Creates a file called ".htaaccess" in the main folder of your site with the example code below.What will happen?When the browser loads the site, the htaacess file will indicate that some files may be cached for X time.<IfModule mod_expires.c> ExpiresActive on ExpiresDefault "access plus 1 month" ExpiresByType text/xml "access plus 0 seconds" ExpiresByType application/xml "access plus 0 seconds" ExpiresByType application/json "access plus 0 seconds" ExpiresByType image/x-icon "access plus 1 week" ExpiresByType image/gif "access plus 1 month" ExpiresByType image/png "access plus 1 month" ExpiresByType image/jpeg "access plus 1 month" ExpiresByType video/ogg "access plus 1 month" ExpiresByType audio/ogg "access plus 1 month" ExpiresByType video/mp4 "access plus 1 month" ExpiresByType video/webm "access plus 1 month" ExpiresByType application/x-font-ttf "access plus 1 month" ExpiresByType font/opentype "access plus 1 month" ExpiresByType application/x-font-woff "access plus 1 month" ExpiresByType image/svg+xml "access plus 1 month" ExpiresByType application/vnd.ms-fontobject "access plus 1 month" ExpiresByType text/css "access plus 1 year" ExpiresByType application/javascript "access plus 1 year" </IfModule>

In a short version:Using PHP:header("Cache-Control: no-cache, no-store, must-revalidate"); // HTTP 1.1. header("Pragma: no-cache"); // HTTP 1.0. header("Expires: 0"); // Proxies. Using HTML:<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" /> <meta http-equiv="Pragma" content="no-cache" /> <meta http-equiv="Expires" content="0" /> This will tell the browser to always renew the cache. Doing so that "never" has cache saved to the page.Original response in: https://stackoverflow.com/questions/49547/how-to-control-web-page-caching-across-all-browsers

That is an answer https://stackoverflow.com/questions/45347160/is-it-better-to-return-an-empty-task-or-null-c-sharp :It is not right to return a Task Nula. One Task Nula is like she's never been called, but she's gone.So, one Task/Task<T> returned from a method never should be null. But still you can return the null value within the Task.What is the problem of returning null on that occasion?In my case, it was probably a false alarm of my analyzer, since I was not returning to Task as null, and null value within Task, which is totally correct.Explaining better, the method https://docs.microsoft.com/en-us/dotnet/api/microsoft.extensions.caching.memory.cacheextensions.getorcreateasync?view=aspnetcore-2.1 the IMemoryCache receives a generic type parameter(<T>), and one Func<ICacheEntry, out Task<T>>, and as my task was asynchronous, when I returned naked, he was not returning to Task as null, but the value within Task, type News[] as null.What is the sense to return a 0ms delay as it recommends?One Task.Delay of 0ms is the same thing of returning a Task.CompletedTask, see how it is implemented in https://github.com/dotnet/coreclr/blob/master/src/System.Private.CoreLib/src/System/Threading/Tasks/Task.cs the /questions/tagged/.net-core : (line 5407 at the time I'm writing)public static Task Delay(int millisecondsDelay, CancellationToken cancellationToken) { // ... if (cancellationToken.IsCancellationRequested) { // return a Task created as already-Canceled return Task.FromCanceled(cancellationToken); } else if (millisecondsDelay == 0) { // return a Task created as already-RanToCompletion return Task.CompletedTask; } // ... }

I can suggest something related to the cache, which in my view makes all the difference when it comes to meeting high volumes of competing transactions/access. This is the framework http://msdn.microsoft.com/en-us/library/ff383731%28v=azure.10%29.aspx , which after long development time is a stable and safe and free system.There are plenty of support material, with http://channel9.msdn.com/Events/TechEd/NorthAmerica/2012/AAP314 and documentation available.
