Prior releases of the 6.x line relied on Lexical::Types, which was a major performance pessimisation over the 5.x releases.

6.0.4 relies on a simple source filter instead, which restores performance levels back to expected levels.

More benchmarks added to the test suite validate the dependency changes.

  • YahooJSON.pm - Added code to retrieve cookies and a "crumb" required to continue to utilize the v11 API. Issue #369. The YahooJSON.pm currency module was changed to use the v8 API.
  • Added initial version of CONTRIBUTING.pod that metacpan.org utilizes. It will completely replace the Hacker's Guide in the future.
  • Bloomberg.pm - Changed module to extract data from JSON structure embedded within the HTML - Issue #360
  • NSEIndia.pm - Eliminated need to use temp folders by storing file data from URL into a variable.

113-bit integer arithmetic

Changes for 0.04

  • Allow negative values to be passed to bitwise operators (&, |, ^, ~, >>, <<). These negative values will be converted to their 113-bit 2s-complement value prior to being acted upon by the bitwise operator - thus mimicking perl's treatment of negative 32-bit/64-bit IVs.
  • Add divmod() function.
  • Add new test file t/bitwise_feature.t




HTTP/2 Dynamic Benchmarks (PHP vs. ModPerl2), 2024 edition.

I ram these about four years ago, and the time differentials were about the same then as now. Monolithic POSIX-threaded server architectures like mp2 + mpm_event will always dominate in low-latency/scalability HTTP/2 benchmarks because they leverage zero-copy in the runtime.

Anyways, sexy terminal graphs with smag to enjoy!

Some basic stat computations with Perl , Python and RLessons learned:
A) Performance freaks to stop using #rstat 's runif for random generation. The Hoshiro random number generator arxiv.org/abs/1805.01407 is 10x faster.
Implementations in #perl 's #PDL, #rstats (dqrng) and #python #numpy are within 20% of each other

B) But does it make a difference in applications? To get to the bottom of this, I coded a truncated random variate generator in #rstats and #perl using #pdl (as well as standard u/perl) using the #GSL packages metacpan.org/pod/PDL::GSL::CDF & metacpan.org/pod/Math::GSL for accessing the CDF & quantile functions. In this context, it's the calculation of the #CDF that is the computationally intensive part, not the drawing of the random number itself.
Well even in these case, the choice of the generator did matter. Note that the fully vectorized #PDL #perl versions were faster than #rstats

C) I should probably blog about these experiments at some point. Note that #pdl (but not base #perl) are rather competitive choices for large array processing with numerical operations. I mostly stay away of #python , but would not surprise me that for compute intensive stuff (where the heavy duty work is done in C/C++), it does not matter (much) which high level language one uses to build data applications

Hi, im working on this perl script wherein i should get all files with filename < 900000

Ex. sample_file_802856.txt sample_file_27364692.txt sample_file_385620.txt

the script should get:

sample_file_802856.txt sample_file_385620.txt

I already have the code but it’s failing on this part coz im having a hard time getting the regex for < 900000 😆
