kandi X-RAY | Improvement Summary
Rails is a web-application framework that includes everything needed to create database-backed web applications according to the Model-View-Control pattern. This pattern splits the view (also called the presentation) into "dumb" templates that are primarily responsible for inserting pre-built data in between HTML tags. The model contains the "smart" domain objects (such as Account, Product, Person, Post) that holds all the business logic and knows how to persist themselves to a database. The controller handles the incoming requests (such as Save New Account, Update Product, Show Post) by manipulating the model and directing data to the view. In Rails, the model is handled by what’s called an object-relational mapping layer entitled Active Record. This layer allows you to present the data from database rows as objects and embellish these data objects with business logic methods. You can read more about Active Record in link:files/vendor/rails/activerecord/README.html. The controller and view are handled by the Action Pack, which handles both layers by its two parts: Action View and Action Controller. These two layers are bundled in a single package due to their heavy interdependence. This is unlike the relationship between the Active Record and Action Pack that is much more separate. Each of these packages can be used independently outside of Rails. You can read more about Action Pack in link:files/vendor/rails/actionpack/README.html.

When a divide-and-conquer recursive function doesn't yield runtimes low enough, which other improvements could be done?
Let's say, for example, this power function taken from here:

Im currently tackling the optimization of combining two arrays. The problem is the following:
- I have 2 Arrays of different sizes with Array A beeing smaller in all cases that Array B (Most of the time with different magnitude)
- Array A contains objects in with two ID's
ANSWER
Answered 2021-Jun-14 at 12:42The problem in both solutions is the need to iterate array A for every item in array B.
Instead create a Set from the 1st array (A) relevant ids, and then filter the 2nd array (b) by checking that the relevant id doesn't appear in the Set:

I am trying to create an HTML page that includes images that play sounds on-click. The first click for every image works great, but subsequent clicks don't always work; they seem to require some refractory load time again?

QUESTION
TLDR: Create a CRC from every file(contentbased) in Directory.
Currently i used from Cpp20 the Filesystem Libary and tried to create a checksum for a file with "hash_value(p)". The thing is, the value does not change. Can you provide me some advice ho to accomplish a checksum, that changes when file content is changed. I would like to stay within the range of CPP libarys or what debian 10 can provide.
Now i tried this:
ANSWER
Answered 2021-Jun-12 at 16:59The thing is, the value does not change.
It's not supposed to. The filesystem::hash_value is a hash of the path to the file, not the contents of the file. If you want to compute a CRC of the contents of a file, you're going to have to read those contents and apply a CRC algorithm to them.
QUESTION
Honestly, I think the code which I've written is trash and I don't think it's the best way to solve the problem. I need a few suggestions or improvements to solve this problem. I'm still new to coding. Appreciate it if you can give some tips on how to work with strings and various string functions.
CONDITIONS FOR THE STRING TO BE AN IP ADDRESS:-
An identification number for devices connected to the internet. An IPv4 addresses written in dotted quad notation consists of four 8-bit integers separated by periods.
In other words, it's a string of four numbers each between 0 and 255 inclusive, with a "." character in between each number. All numbers should be present without leading zeros.
Examples:
- 192.168.0.1 is a valid IPv4 address
- 255.255.255.255 is a valid IPv4 address
- 280.100.92.101 is not a valid IPv4 address because 280 is too large to be an 8-bit integer (the largest 8-bit integer is 255)
- 255.100.81.160.172 is not a valid IPv4 address because it contains 5 integers instead of 4
- 1..0.1 is not a valid IPv4 address because it's not properly formatted
- 17.233.00.131 and 17.233.01.131 are not valid IPv4 addresses because they contain leading zeros
Here's my code (I know it's trash and doesn't make any sense):-
...ANSWER
Answered 2021-Jun-11 at 19:35You had a lot of loose 47, 48, etc. values for things like '0'. Better to use the latter syntax.
There were a number of if range checks. Using some additional state variables can reduce the complexity.
Using inputString[i] everywhere is cumbersome. Better to do (e.g. int chr = inputString[i]; and use chr instead--it's simpler and easier to read).

I rebuilt the project completely, made it with divs and flexbox, and filled the slots by using simple JavaScript (instead of using margin-left in the SCSS).
Also, I built the project in React.

QUESTION
I'm looking for some help since I don't know how to optimize a process.
I have to invoke a service that returns a list with more than 500K elements (I don't know why, these services belongs to the client), per each element of the list, I have to invoke 2 more services and then save some attributes in our database, this last step is not the problem, but the entire process took between 1 and 2 seconds per element, so with this time is going to take like more of 100 hours to complete the process. My approach is the following, I have my main method, inside this method I get the large list, then I use a parallelStream to iterate in the elements of the list and then I use a CompletableFuture to call the method that invokes the 2 services mentioned above. I've tried changing the parallelStream to stream and for-each , tried to split the main list into smaller lists and many other things but I don't see a better performance, I think the problem is the invocation of those 2 services but I want to try luck asking here.
I'm using java 11, spring, and for the invocation of the services I'm using RestTemplate, and this is my code:
