This is the frame body I was using:
our $frame_body = $mw->Frame(-background => $color_theme_bg, -foreground => $color_theme_fg)->pack(-side => 'top');
And I have many widgets like labels, dropdowns, buttons, etc... within that frame like below:
$frame_body ->Label( -text => "@_", -font => $arial_font, -foreground => $color_theme_fg, -background => $color_theme_bg, -highlightthickness => 0, -takefocus => 0, -relief => "flat", -justify => 'center', )-> grid( -column => $mw_col_ctr, -row => $mw_row_ctr, -sticky => "nsew", );
May someone help me the best way to apply a "vertical scroll bar" on the right side of this frame?
Its also nice if automatically adjust incase I manually resize the window. 😀

I need to find the distance between two GPS coordinates. Geo::Calc does this effectively, but it hasn't been updated in over a decade, and, more seriously, it adds a significant startup delay just by loading the module:
root@1c8fb16bd7bb:/app# time perl -e 'use v5.38' real 0m0.005s user 0m0.001s sys 0m0.004s root@1c8fb16bd7bb:/app# time perl -e 'use v5.38; use Geo::Calc' real 0m0.679s user 0m0.631s sys 0m0.048s
This isn't a deal-breaker (honestly, it barely matters at all in production, but it's annoying for repeated loads during dev/testing), but I was wondering if anyone knew of a more-modern/more-efficient alternative. I searched google and metacpan but it's tough to wade through the noise for such a generic search term.

The portions of B::Generate associated with PADOP construction use static variables, and thus are not thread safe.
This release imports that section of Generate.xs into sealed.xs and removes the static variable dependencies.

Use bash , ncal , Perl to list years, months, and weeks with week numbers - gist:efa21bd6374824ba8332a3a4ac7b4585Gist
I am hopeful someone has done this before as I'm stuck... I have a 3TB disk image file and I am trying to find all the different email addresses that I've used over the past 22 years.
I can use hex editor tools to find them but it takes days to look at the data and pick out even a handful of matches.
I use Perl regularly but I normally scan text files and do non binary file actions. That's easy since I can do a line by line search. But binary seems different.
If I want to search for zeropoint@ (no domain because I've used dozens of ISPs over the years and that's why I am trying to figure this out.) inside the entire 3TB file, what's the best way to do that? I can dump the results to a file and then clean it up but the search part has me stuck
Thank you

Although Benchmark::DKbench is a good overall indicator for generic CPU performance for comparing different systems (especially when it comes to Perl software), the best benchmark is always your own code. Hence, the module now lets you incorporate your own custom benchmarks. You can either have them run together with the default benchmarks, or run only your own set, just taking advantage of the framework (reports, multi-threading, monotonic precision timing, configurable repeats with averages/stdev, calculation of thread scaling etc). Here's an example where I run a couple of custom benchmarks on their own with Benchmark::DKbench:
``` use Benchmark::DKbench;
A simplistic benchmark sub:
sub str_bench { for (1..1000) { my $str = join("", map { chr(97 + rand(26)) } 1..rand(15000)); $str =~ s/a/bd/g; $str =~ tr/b/c/; } }
my %stats = suiterun({ include => 'custom', # Run only my custom benchmarks iter => 5, # Iterations to get an average extra_bench => { custom_bench1 => [&str_bench], # Add one more, just inline this time: custom_bench2 => [sub {my @a=split(//, 'x'x$) for 1..5000}], } }); ``` This will produce a report in STDOUT and also return the results in a hash for a single-thread run. You can also run the benchmarks multi-treaded and then calculate & print the multi/single-thread scalability:
```
If you want to get a count of logical cores:
my $cores = system_identity(1);
my %statsmulti = suite_run({ include => 'custom', threads => $cores, iter => 5, extra_bench => { custom_bench1 => [&str_bench], custom_bench2 => [sub {my @a=split(//, 'x'x$) for 1..5000}], } });
my %scal = calc_scalability(\%stats, \%stats_multi); ```
The report prints results per iteration and also aggregates:
``` Aggregates (5 iterations): Benchmark Avg Time (sec) Min Time (sec) Max Time (sec) custom_bench1: 1.092 1.079 1.107 custom_bench2: 0.972 0.961 0.983 Overall Avg Time (sec): 2.065 2.048 2.080
Aggregates (5 iterations, 10 threads): Benchmark Avg Time (sec) Min Time (sec) Max Time (sec) custom_bench1: 1.534 1.464 1.651 custom_bench2: 1.278 1.225 1.345 Overall Avg Time (sec): 2.812 2.689 2.965 The scalability report summarizes as well:
Multi thread Scalability: Benchmark Multi perf xSingle Multi scalability % custom_bench1: 7.12 71
custom_bench2: 7.61 76
DKbench summary (2 benchmarks, 5 iterations, 10 threads): Single: 2.065s Multi: 2.812s Multi/Single perf: 7.36x (7.12 - 7.61) Multi scalability: 73.6% (71% - 76%) ```
The suite normally uses a scoring system which works better than times, so you can set that up by adding reference times to each benchmark, and you can also make the benchmarks return something (checksum etc) to verify results etc, see POD for more.

Hi! Asking for a wisdom here...
We have a module that modifies signal handler $SIG{__DIE__} to log information and to die afterwards. Hundreds of scripts relied on this module which worked fine in perl 5.10.1.
Recently we had the opportunity to install several Perl versions but unfortunately a large number of scripts that used to work with Perl 5.10.1 now behave differently:
- Failed in 5.14.4:
/home/dev/perl-5.14.4/bin/perl -wc
test.pl
RECEIVED SIGNAL - S_IFFIFO is not a valid Fcntl macro at /home/dev/perl-5.14.4/lib/5.14.4/File/stat.pm line 41
- Worked without changes in 5.26.3:
/home/dev/perl-5.26.3/bin/perl -wc
test.pl
test.pl
syntax OK
- Worked without changes in 5.38.2:
/home/dev/perl-5.38.2/bin/perl -wc test.pl
test.pl syntax OK
Many of the scripts can only be updated to 5.14.4 due to the huge jumps between 5.10 and 3.58; But we are stuck on that failures.
Was there an internal Perl change in 5.14 which cause the failures but works on other recent versions without any update on the scripts?
Cheerio!
