            Reverser function that can group the value whit in a cell
            Asked 2022-Apr-07 at 13:56

            I have been searching and doing some study on all the different posts I could find but can't say this request or question has been discussed before.

            This is basic reverse funktion, what I´ll like to accomplish is (as I call it) a group reversed function. Will Attach a picture to graphicly explain this better.

            The goal is then to use =StrReverse($A1)

            polynomial (in n) time algorithm that decides whether N is a power
            Asked 2022-Apr-02 at 22:23

            I am a computer science student; I am studying the Algorithms course independently.

            During the course, I saw this question:

            Given an n-bit integer N, find a polynomial (in n) time algorithm that decides whether N is a power (that is, there are integers a and k > 1 so that a^k = N).

            I thought of a first option that is exponential in n: For all k , 1

            For example, if N = 27, I will start with k = 2 , because 2 doesn't divide 27, I will go to next k =3. I will divide 27 / 3 to get 9, and divide it again until I will get 1. This is not a good solution because it is exponential in n.

            My second option is using Modular arithmetic, using ak ≡ 1 mod (k+1) if gcd(a, k+1 ) = 1 (Euler's theorem). I don't know if a and k are relatively prime.

            I am trying to write an algorithm, but I am struggling to do it:



            Answered 2022-Mar-15 at 10:07

            Ignoring the cases when N is 0 or 1, you want to know if N is representable as a^b for a>1, b>1.

            If you knew b, you could find a in O(log(N)) arithmetic operations (using binary search). Each arithmetic operation including exponentiation runs in polynomial time in log(N), so that would be polynomial too.

            It's possible to bound b: it can be at most log_2(N)+1, otherwise a will be less than 2.

            So simply try each b from 2 to floor(log_2(N)+1). Each try is polynomial in n (n ~= log_2(N)), and there's O(n) trials, so the resulting time is polynomial in n.

            Studying Go generics, I'm running into an error I can't seem to untangle. I've boiled it down to the simplest code:



            Answered 2022-Feb-26 at 06:13

            because you want

            t = append(t, 0)

            the data type can be int or float group.

            this code should work

            Removing signs and repeating numbers

            I want to remove all signs from my dataframe to leave it in either one of the two formats: 100-200 or 200

            So the salaries should either have a single hyphen between them if a range of salaries if given, otherwise a clean single number.

            Answered 2022-Jan-12 at 08:50

            You can do it in only two regex passes. First extract the monetary amounts with a regex, then remove the thousands separators, finally, join the output by group keeping only the first two occurrences per original row.

            The advantage of this solution is that is really only extracts monetary digits, not other possible numbers that would be there if the input is not clean.



            Julia equivalent for rgl R package?
            Asked 2022-Jan-06 at 22:13

            I would like to know whether there exists in Julia something which would be rougly equivalent to the rgl package in R language; i.e., a library allowing for a dynamic/interactive representation of 3D plots, 3D surfaces, etc.

            A bit of context: if you're studying, for example, morphometrics, you regularly end up with files in PLY format, or another format produced by 3D scanners. In R, you can for instance visualize (in an interactive way) easily a 3D surface acquired by such a scanner (here, a set of molars):

            Do we have currently a similar feature in Julia? If so, which library should I use?




            Answered 2022-Jan-06 at 22:13

            Makie.jl, specifically via either the GLMakie.jl or WebGLMakie.jl backends, is a good option for interactive plots. For instance, the following example from the BeautifulMakie gallery



            small object optimization useless in using std::function
            Asked 2022-Jan-05 at 10:06

            Many topics told us that use small object like lambda expression could avoid heap allocation when using std::function. But my study shows not that way.

            This is my experiment code, very simple



            Answered 2022-Jan-05 at 09:28

            Older versions of libstdc++, like the one shipped by gcc 4.8.5, seem to only optimise function pointers to not allocate (as seen here).

            Since the std::function implementation does not have the small object optimisation that you want, you will have to use an alternative implementation. Either upgrade your compiler or use boost::function, which is essentially the same as std::function.



            How to allow to use the master password in Laravel 8 by overriding Auth structure?
            Asked 2022-Jan-03 at 05:36

            I've got a website written in pure PHP and now I'm learning Laravel, so I'm remaking this website again to learn the framework. I have used built-in Auth Fasade to make authentication. I would like to understand, what's going on inside, so I decided to learn more by customization. Now I try to make a master password, which would allow direct access to every single account (as it was done in the past).

            Unfortunately, I can't find any help, how to do that. When I was looking for similar issues I found only workaround solutions like login by admin and then switching to another account or solution for an older version of Laravel etc.

            I started studying the Auth structure by myself, but I lost and I can't even find a place where the password is checked. I also found the very expanded solution on GitHub, so I tried following it step by step, but I failed to make my own, shorter implementation of this. In my old website I needed only one row of code for making a master password, but in Laravel is a huge mountain of code with no change for me to climb on it.

            As far I was trying for example changing all places with hasher->check part like here:



            Answered 2021-Dec-29 at 02:54

            Here is a possible solution.

            To use a master password, you can use the loginUsingId function

            Search the user by username, then check if the password matches the master password, and if so, log in with the user ID that it found



            Should I use Redux or Redux-Toolkit?
            Asked 2021-Dec-26 at 03:16

            I am new in studying Redux. Then I know the existence about Redux-toolkit. My question is which should I use? Can Redux-toolkit replace Redux core?



            Answered 2021-Dec-26 at 03:16

            Redux used to be great but if you have tried none of them, I would highly recommend using Redux-Toolkit. The only case where I may want you to stick to redux is when you're using class-based components, where Redux Toolkit does have some boilerplate (like Redux) and you may miss out decent support.

            However with functional components, Redux toolkit is like Redux on steroids.

            Reason for using Redux toolkit:

            1. A lot lesser boilerplate code is required compared to Redux.

            2. Redux hooks like useSelector and useDispatch make things so short and easy to use.

            3. You don't need to do manual thunk setup as redux-toolkit comes with out of the box createAsyncThunk which enables you to perform async operations in very hastle free way.

            4. getState is also very helpful in obtaining state variables across any of your actions or async operations.

            5. Mutability might be considered as advantage or disadvantage, but if you're not too used to writing with spread operators, you might love this feature as well. Do straight assignments and let redux toolkit take care of mutability under the hoods.

            6. current can be used to log your state anywhere in case you want to debug and understand where things are going wrong. (Ofcourse, Redux debugger tools are great as well)

            7. Prebuilt templates you might want to use npx create-react-app my-app --template redux-typescript or if you're using it with next: yarn create next-app --example with-redux with-redux-app. It gives you a setup ready redux toolkit boiler plate and also contains a boiler plate of most important redux state management applications so that you could refer them to create your own slices very easily.

            I have been using a lot of redux and initially it was a bit confusing but once you get a good command over redux toolkit and if you're using a lot of functional components, you probably would never go back to redux again.
