From the cpython source code for sum sum initially seems to attempt a fast path that assumes all inputs are the same type. If that fails it will just iterate:

The error is being caused because one of your dependencies is internally using WorkManager 2.7.0-beta01 that was released today (which needs API 31). In my case it was CheckAarMetadata.kt.

You can fix it by forcing Gradle to use an older version of Work Manager for the transitive dependency that works with API 30. In your build.gradle file add:

You can use the std::nextafter function, which, despite its name, can retrieve the next representable value that is arithmetically before a given starting point, by using an appropriate to argument. (Often -Infinity, 0, or +Infinity).

This works portably by definition of nextafter, regardless of what floating-point format your C++ implementation uses. (Binary vs. decimal, or width of mantissa aka significand, or anything else.)

Example: Retrieving the closest value less than 1 for the double type (on Windows, using the clang-cl compiler in Visual Studio 2019), the answer is different from the result of the 1 - ε calculation (which as discussed in comments, is incorrect for IEEE754 numbers; below any power of 2, representable numbers are twice as close together as above it):

Gatsby must be using an algorithm or key size which is no longer allowed by default with OpenSSL 3.0.

UPDATE ⚠️

This is most likely a webpack issue - https://github.com/webpack/webpack/issues/14532

They have since released a fix in version 5.61.0 - https://github.com/webpack/webpack/releases/tag/v5.61.0 - so upgrading webpack should address the issue as well

A member of the webpack team has stated they do not plan to backport the fix to webpack 4, so if you are on webpack 4 you may need to look to upgrading to webpack 5 first.

From Node.js 17's announcement post:

If you hit an ERR_OSSL_EVP_UNSUPPORTED error in your application with Node.js 17, it’s likely that your application or a module you’re using is attempting to use an algorithm or key size which is no longer allowed by default with OpenSSL 3.0. A new command-line option, --openssl-legacy-provider, has been added to revert to the legacy provider as a temporary workaround for these tightened restrictions.

Running this on the terminal might look like:

Code readability, short-circuiting and it is not guaranteed that Ord will always outperform a || operand. Computer systems are more complicated than expected, even though they are man-made.

There was a case where a for loop with a much more complicated condition ran faster on an IBM. The CPU didn't cool and thus instructions were executed faster, that was a possible reason. What I am trying to say, focus on other areas to improve code than fighting small-cases which will differ depending on the CPU and the boolean evaluation (compiler optimizations).

Since C++17 the order of evaluation is specified such that the operands of = are evaluated right-to-left and those of << are evaluated left-to-right, matching the associativity of these operators. (But this doesn't apply to all operators, e.g. + and other arithmetic operators.)

So in

The JNDI feature was added into Log4j 2.0-beta9.

Log4j 1.x thus does not have the vulnerable code.

Seems a bug of openssl itself. https://github.com/openssl/openssl/issues/16487

~~What about export SDKROOT="/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk "?~~

Homebrew pre-build packages for some versions of macOS. But it keep dropping this pre-building support for old macOS. On macOS 10.12, you're building openssl from the source code and Xcode command line tool is needed.

(fastest methods, 3 and 4, are at the end)

In a fast NumPy method you need to specify dtype=np.object so that NumPy does not convert Python int to its own dtypes (np.int64 or others). It will now give you correct results (checked it up to N=100000).
