            How to implement memoization in Scala without mutability?
            Asked 2022-Mar-23 at 21:05

            I was recently reading Category Theory for Programmers and in one of the challenges, Bartosz proposed to write a function called memoize which takes a function as an argument and returns the same one with the difference that, the first time this new function is called, it stores the result of the argument and then returns this result each time it is called again.

            Is there any way that I can get Google access tokens only using API?
            Asked 2022-Feb-18 at 16:32

            I am building an RPA process to integrate with Google AI Document and one of the challenges I've encountered is getting the access token and using it during the API call. Most of the time I'm just using powershell by running gcloud auth application-default print-access-token script in order to get the token.

            Is there any other way that I can do in order to get that token perhaps by authorizing through an API call or anything?

            Use gcloud auth application-default print-access-token --log-http to view the API call that perform the GCLOUD sdk and get inspiration from them.

            The content that you will see is sensitive and the logs are deactivated by default. To view them perform a gcloud config set log_http_redact_token false to view unredacted logs.

            The root cause appear to be missing executable flag on Contents/bin/printenv file.

            MySQL SQL Performance need some improvement
            Asked 2022-Jan-13 at 01:35

            I have worked my way around many challenges with MySQL, and i think right now i am able to build everything that i need, to get something to work. But now, for a pretty huge SQL statement that returns a lot of data, i need to work on MySQL performance for the first time.

            I was hoping someone here could help me find out why the following statement is so incredibly slow. It takes over 3 minutes to collect 740 results out of different tables. The biggest table beeing the "reports" table, consisting of somewhere over 20.000 entries at the moment.

            I can also educate myself if someone could just point me in the right direction. I don't even know where to search for answers for my current problem.

            Okay, so here is the statement that i am talking about. Maybe, if someone has enough experience with SQL performance, something just right away jumps at them. I would be happy for any kind of feedback. I'll elaborate on the statement right after the code itself:

            Boost::Spirit doubles character when followed by a default value
            Asked 2022-Jan-10 at 13:19

            I use boost::spirit to parse (a part) of a monomial like x, y, xy, x^2, x^3yz. I want to save the variables of the monomial into a map, which also stores the corresponding exponent. Therefore the grammar should also save the implicit exponent of 1 (so x stores as if it was written as x^1).

            I think I solved the original problem myself. The second try works.

            Indeed. It's how I'd do this (always match the AST with your parser expressions).

            However, I don't see how I doubled the variable name.

            It's due to backtracking with container attributes. They don't get rolled back. So the first branch parses potVar into a string, and then the parser backtracks into the second branch, which parses potVar into the same string.

            It can also crop up with semantic actions:

            Reading list of URLs from .csv for scraping with Python, BeautifulSoup, Pandas
            Asked 2021-Nov-27 at 22:49

            This was part of another question (Reading URLs from .csv and appending scrape results below previous with Python, BeautifulSoup, Pandas ) which was generously answered by @HedgeHog and contributed to by @QHarr. Now posting this part as a separate question.

            In the code below, I'm pasting 3 example source URLs into the code and it works. But I have a long list of URLs (1000+) to scrape and they are stored in a single first column of a .csv file (let's call it 'urls.csv'). I would prefer to read directly from that file.

            I think I know the basic structure of 'with open' (e.g. the way @bguest answered it below), but I'm having problems how to link that to the rest of the code, so that the rest continues to work. How can I replace the list of URLs with iterative reading of .csv, so that I'm passing the URLs correctly into the code?

            I got this code to almost work, despite much ignorance. Please help on the home run!

            • Problem 1: INPUT:

            I have a long list of URLs (1000+) to read from and they are in a single column in .csv. I would prefer to read from that file than to paste them into code, like below.

            • Problem 2: OUTPUT:

            The source files actually have 3 drivers and 3 challenges each. In a separate python file, the below code finds, prints and saves all 3, but not when I'm using this dataframe below (see below - it only saves 2).

            • Problem 3: OUTPUT:

            I want the output (both files) to have URLs in column 0, and then drivers (or challenges) in the following columns. But what I've written here (probably the 'drop') makes them not only drop one row but also move across 2 columns.

            At the end I'm showing both the inputs and the current & desired output. Sorry for the long question. I'll be very grateful for any help!

            Assert that a dynamic table is correctly ordered by date
            Asked 2021-Nov-18 at 18:41

            Given a dynamically-loading table with a variable number of rows, how does one assert that the rows are correctly ordered by date?

            This problem has two main challenges: (1) how does one compare dates within table rows using cypress; and (2) how does one handle dynamic loading in such a complex scenario?

            So far, I have successfully managed to solve the first problem; however, I am unable to solve the second problem. My test works most of the time, but it will sometimes fail because the page hasn't finished loading before the assertions are hit. For example, the dates are out of order when the page is first loaded:

            ANSWER

            Answered 2021-Nov-18 at 12:48

            You need to use a single cy.get(...).should(...) callback where the callback grabs all date strings, converts into timestamps, then checks if the timestamps are sorted. Then Cypress retries the cy.get command - until the table is sorted and the should callback passes. Here is a sample code, see the full dynamic example at https://glebbahmutov.com/cypress-examples/recipes/sorted-list.html
