            You can call next() with a generator or iterator as an argument to withdraw exactly one element from it. Saving the generator to a variable beforehand allows you to do this multiple times.

            Why is `np.sum(range(N))` very slow?
            Asked 2022-Mar-29 at 14:31

            I saw a video about speed of loops in python, where it was explained that doing sum(range(N)) is much faster than manually looping through range and adding the variables together, since the former runs in C due to built-in functions being used, while in the latter the summation is done in (slow) python. I was curious what happens when adding numpy to the mix. As I expected np.sum(np.arange(N)) is the fastest, but sum(np.arange(N)) and np.sum(range(N)) are even slower than doing the naive for loop.

            Why is this?

            Here's the script I used to test, some comments about the supposed cause of slowing done where I know (taken mostly from the video) and the results I got on my machine (python 3.10.0, numpy 1.21.2):

            QUESTION

            How would you implement a lazy "range factory" for C++20 ranges that just calls a generator function?
            Asked 2022-Feb-17 at 17:10

            I like the idea of the lazy ranges you can make with std::views::iota but was surprised to see that iota is currently the only thing like it in the standard; it is the only "range factory" besides views::single and views::empty. There is not currently, for example, the equivalent of std::generate as a range factory.

            I note however it is trivial to implement the semantics of generate by using a transform view on iota and just ignoring the value iota passes to transform i.e.

            Answered 2022-Feb-17 at 17:10

            The reason why generate2 cannot work is that it does not model the range concept, that is, the type returned by its begin() does not model input_iterator, because input_iterator requires difference_type and value_type to exist and i++ is a valid expression.

            In addition, your iterator does not satisfy sentinel_for, which means that it cannot serve as its own sentinel, because sentinel_for requires semiregular which requires default_initializable, so you also need to add default constructors for it.

            You also need to rewrite bool operator!=(...) to bool operator==(...) const since operator!= does not reverse synthesize operator==. But it's easier to just use default_sentinel_t as sentinel in your case.

            if you add them to iterator you will find the code will be well-formed:

            Can you compress angular image assets on build?
            Asked 2022-Jan-15 at 12:13
            What I want

            I have very big images in my assets, which slows down the site by a lot for slower networks. (you can read more about the topic on this lighthouse linked page)

            • I would like to compress them at build time (ng build --prod).
            • For local development, it is irrelevant (ng serve).
            • Optimally I would like to generate multiple versions for different screen sizes (example.jpg → should become: example_x265.jpg, example_x128.jpg, ...)
            What I have tried

            The most promising guide I have found for that is this one here, which describes how to use the imagemin package in combination with the ngx-build-plus package.

            Answered 2022-Jan-10 at 08:29

            I used yield and re.finditer.

            The yield expression is used when defining a generator function or an asynchronous generator function and thus can only be used in the body of a function definition. Using a yield expression in a function’s body causes that function to be a generator function

            Return an iterator yielding match objects over all non-overlapping matches for the RE pattern in string. The string is scanned left-to-right, and matches are returned in the order found. Empty matches are included in the result.
            If there are no groups, return a list of strings matching the whole pattern. If there is exactly one group, return a list of strings matching that group. If multiple groups are present, return a list of tuples of strings matching the groups. Non-capturing groups do not affect the form of the result.

            The regular expression ([^\r\n]*)(\r\n|\r|\n)? can be divided into two parts to match (that is, two groups). The first group matches the data without \r and \n, and the second group matches \r, \n or \r\n.

            Problem Updating to .Net 6 - Encrypting String
            Asked 2021-Dec-20 at 23:09

            I'm using a string Encryption/Decryption class similar to the one provided here as a solution.

            This worked well for me in .Net 5.
            Now I wanted to update my project to .Net 6.

            When using .Net 6, the decrypted string does get cut off a certain point depending on the length of the input string.

            ▶️ To make it easy to debug/reproduce my issue, I created a public repro Repository here.

            • The encryption code is on purpose in a Standard 2.0 Project.
            • Referencing this project are both a .Net 6 as well as a .Net 5 Console project.

            Both are calling the encryption methods with the exact same input of "12345678901234567890" with the path phrase of "nzv86ri4H2qYHqc&m6rL".

            .Net 5 output: "12345678901234567890"
            .Net 6 output: "1234567890123456"

            The difference in length is 4.

            I also looked at the breaking changes for .Net 6, but could not find something which guided me to a solution.

            I'm glad for any suggestions regarding my issue, thanks!

            The reason is this breaking change:

            DeflateStream, GZipStream, and CryptoStream diverged from typical Stream.Read and Stream.ReadAsync behavior in two ways:

            They didn't complete the read operation until either the buffer passed to the read operation was completely filled or the end of the stream was reached.

            And the new behaviour is:

            Starting in .NET 6, when Stream.Read or Stream.ReadAsync is called on one of the affected stream types with a buffer of length N, the operation completes when:

            At least one byte has been read from the stream, or The underlying stream they wrap returns 0 from a call to its read, indicating no more data is available.

            In your case you are affected because of this code in Decrypt method:

            Ok, I actually solved this problem by poking around through OpenApiReference, but it requires manual modification of csproj file. Additional Options node has to be added to OpenApiReference item group, to instruct NSwag to NOT expose BaseUrl and to also generate an interface, which eases the work with setting up DI without additional code.

            Visual Studio team should really add these two checkboxes to Connected Services screens/configuration for OpenAPI.
