QUESTION
My Question: What exactly does “compile-time” mean? I present my understanding below and where I am getting confused.
Compilation is the process that generates a single executable .exe file from the .vb file. There are several ways to do this, for example by using the VBC.EXE command from the developer command window or MSDOS. The way I understand “compile-time” is that it is time when such a command gets executed and the exe file is generated. The following are the what I find confusing:
- When I write Dim i = 5, the compiler infers or “knows” that the variable “i” is an integer.
- If I want to print an integer or a string using the Writeline method of the console class then the compiler automatically determines which overloaded version it should call. So in this case also the compiler “knows” – this is also known as compile-time polymorphism.
My confusion: Since in both the above cases the compiler infers or knows the type of variable or the version of the overloaded method to call just after we have finished typing the sentence, is this also called compile-time? We have not given any sort of compilation command here.
- Another confusion on the definition of compile-time refers to the case when we explicitly define overloaded methods. In the case of the writeline method, we know from the pop-up given by intellisense that immediately after we have finished typing the sentence the version with the correct signature is called. Now, when we define overloaded methods does the compiler know which version to call when we call the function (depending on signature) somewhere in the program right after we have finished typing the code? Or does the compiler know this after the exe file has been generated? This is a case of compile-time polymorphism. But then which time or which step is the “compile-time”?

No, but most modern IDEs can do similar "static analysis" that compilers do to determine types, etc. Some even do a very lightweight "compile" to determine what overloads are appropriate, etc.
Also note that IDEs and the actual compiler may not always agree. IDE analysis is designed to be very fast, so the analysis done by the IDE may be less robust and less accurate than a static compiler.
So in a sense these are all "compile-time" in that the only information that is available is what is present in the code. This is opposed to "run-time" where other factors such as user input, environment, and state can change the flow and interpretation of the program in ways that the compiler could not account for.
QUESTION
How can one check if an integer is equal to another in a 2D array?
...ANSWER
Answered 2021-Jun-15 at 18:23Just to address your attempt, the correct syntax for that would be
if (a == b || a == c || a == d || a == e || a == f || a == g || a == h || a == i) ....
But depending on your use case, it's probably advisable to loop over the array instead.

It depends from where you start the script. If you start it from the top level directory of both folders then it should work.
toplevel/ package/ init.py code.py notebooks/ testing.ipynb
For instance, with the above directory structure, launch testing.ipynb with toplevel being your working directory.

...ANSWER
Answered 2021-Jun-15 at 14:36Not yet no. Here is a specs issue discussing this very matter, and it is something a lot of actors would like to see, so there is hope it comes, one day.
Note that there is an AudioWorklet API available, which will create its own Worklet (which also works in a parallel thread), but you still need to instantiate it from the UI thread, and you don't have access to everything that can be done in an AudioContext. Still, it may suit your needs.
Also, note that it might be possible to do the computing you have to do in a Worker already, by transferring ArrayBuffers from your UI thread to the Worker's one, or by using SharedArrayBuffers.

QUESTION
I want to create a Google script to check if a given URL is indexed by Google, so I write the following function:
...ANSWER
Answered 2021-Jun-15 at 06:28Unfortunately doing this directly by attempting to web scrape the search results using UrlFetchApp will not work. You can use third party tools to get the number of search results, however.
More Information:I tested this out using an exponential backoff method which sometimes is able to get past 429 errors when a fetch request is invoked by UrlFetchApp.
When using UrlFetchApp to either web scrape or to connect to an API, it can happen that the server denies the request on the grounds of too many requests - or HTTP Error 429.
Google Apps Script runs in the cloud, from a set of IP addresses in a pool that Google own. You can actually see all the IP ranges here. Most websites (especially large companies such as Google) have architecture in place to prevent the use of bots scraping their websites and slowing down traffic.
Sometimes it's possible to get past this error, using a mixture of exponential backoff and random time intervals as shown for the Binance API (Full Disclosure: this GitHub repository was written by me.)
I assume that either Google directly blocks the Apps Script IP pool, or there are simply too many people trying the same thing - because with the same techniques I was unable to get any response that didn't involve entering a captcha as we discussed in the comments above and can be seen in the log of the page string.
There are many third party APIs that you can use to do this, and I suggest searching for one that meets your needs.
I tested out one called Authoritas which returns search engine indexing for different keywords. The API is asynchornous, so can take up to a minute to get a response, so a Web App solution needs to be made.
The flow I used is as follows:
- Obtain API key from Authoritas (free)
- Create a new Apps Script project to make an API call:

I'm trying to use LazyCache (https://github.com/alastairtree/LazyCache) to cache some API requests.
The code goes as this:
...ANSWER
Answered 2021-Jun-14 at 20:55I think you need to explicitly create Func delegate in this case, otherwise F# compiler cannot distinguish between the two overloads.
The type of the second argument (in the basic case) is Func<'T> i.e. a function taking unit and returning the value to be cached. This also means that, inside this function, you should call doAPIStuff with the parameters as arguments.
Assuming this is in some actualRequest handler that takes some, parameters, the following should work:
