Just Aristotle and Graham.
The notes from this meeting were lost, but have been reconstructed from memory.
These are some answers to the Week 288, Task 1, of the Perl Weekly Challenge organized by Mohammad S. Anwar.
Spoiler Alert: This weekly challenge deadline is due in a few days from now (on September 29, 2024, at 23:59). This blog post provides some solutions to this challenge. Please don’t read on if you intend to complete the challenge on your own.
You are given a string, $str, which is an integer.
Write a script to find out the closest palindrome, not including itself. If there are more than one then return the smallest.
The closest is defined as the absolute difference minimized between two integers.
Example 1
Input: $str = "123"
Output: "121"

Hi All

The Perl wiki has been renamed from Perl.html - which was too generic - to Perl.Wiki.html:

The schedule for this year's London Perl & Raku Workshop is now visible: https://act.yapc.eu/lpw2024/schedule. Please please please (please please) make a point to mark those talks that you plan to attend as this will allow us to tweak the schedule a bit if some talks are more heavily favourited than others.
The venue opens for attendees at 9am and we plan to start talks at 9:30am. Drinks will be available throughout the day, hence no need to have dedicated breaks there. Lunch will be at midday for an hour, there are plenty of options close to the venue to grab something to eat. If we receive a couple more sponsors we can have lunch at the venue, but currently that won't be possible.
There are a couple of spots left for talks, otherwise the schedule is full. Please don't let this put you off submitting a talk as it's possible some speakers may have to change their plan.
Just Aristotle and Philippe this time (Graham chipped in on IRC):
use VERSION.
Should "did you use VERSION?" become the new "did you use strict and warnings?"These are some answers to the Week 287, Task 2, of the Perl Weekly Challenge organized by Mohammad S. Anwar.

You are given a string, $str.
Write a script to find if it is a valid number.
Conditions for a valid number:
- An integer number followed by an optional exponent.
- A decimal number followed by an optional exponent.
- An integer number is defined with an optional sign '-' or '+' followed by digits.
Decimal Number:
A decimal number is defined with an optional sign '-' or '+' followed by one of the following definitions: - Digits followed by a dot '.'. - Digits followed by a dot '.' followed by digits. - A dot '.' followed by digits.
Exponent:
Earlier today I read a post from Neil Bowers inviting CPAN authors to consider being involved in CPAN day, which is coincidentally today.
It prompted me to take a serious look at the modules I have uploaded to CPAN and acknowledge that some of them are no longer valuable. Indeed as I reviewed one of them I was none too kind in my judgements against the author.
That made it quite easy for me to see how I can easily participate in CPAN day. I'm removing a couple of modules:
Those are now scheduled for deletion on Monday next week.
I'll need to review some of the others and consider whether to open them up for anyone who is interested to take over as maintainer.
For now I've done my bit.
Sometimes the unexpected happens and must be shared with the world … this one is such a case.
Recently, I’ve started experimenting with Perl for workflow management and high-level supervision of low level code for data science applications. A role I’d reserve for Perl in this context is that of lifecycle management of memory buffers, using the Perl application to “allocate” memory buffers and shuttle it between computing components written in C, Assembly, Fortran and the best hidden gem of the Perl world, the Perl Data Language. There at least 3 ways that Perl can be used to allocate memory buffers:
xe.com is a well known site for calculating the exchange value between the currencies of the world. However, there are times I’d prefer to query it from the command line. They have an API, but it’s not free, so I ended up writing a quick and dirty script that scrapes the web page and uses regexps to extract the data.
I know you’re not supposed to parse HTML with regexps, but sometimes, you can get away with it for a while. Also, this script is not that serious, so it can fail without hurting anything.

You are given a string, $str.
Write a program to return the minimum number of steps required to make the given string very strong password. If it is already strong then return 0.
Criteria:
- It must have at least 6 characters.
- It must contain at least one lowercase letter, at least one upper case letter and at least one digit.
- It shouldn't contain 3 repeating characters in a row.
Following can be considered as one step:

Why does this not give flinstone and rubble?
$fn{"fred"} = "flintstone";
$fn{"barney"} = "rubble";
foreach $per (qw< barney fred >) {
print " he's $per $fn($per).\n";
}
Yep, that's right - the first dozen talks have been accepted for this year's London Perl and Raku Workshop. This puts our schedule at approximately 50% full, so if you are thinking about talking at the workshop then submit your proposal now!
If you aren't thinking about talking then have a think about what you've been doing in the Perl and/or Raku space the last five years, or even just the general IT and development space. Perhaps there's something interesting you can talk about? If you don't feel it's a full fat talk then submit a lightning talk instead.
The London Perl and Raku Workshop will take place on 26th Oct 2024. Thanks to this year's sponsors, without whom LPW would not happen:

These are some answers to the Week 286, Task 2, of the Perl Weekly Challenge organized by Mohammad S. Anwar.

You are given an array of integers, @ints, whose length is a power of 2.
Write a script to play the order game (min and max) and return the last element.
Example 1
After over a month without a PSC meeting, this was the first meeting of the new, shiny PSC. Today, we:
I created a function in Perl called pg_dt, that will convert PostgreSQL’s datetime values into Perl’s DateTime values and vice versa. This is useful both when you want to store DateTime values into the database, or want to convert the pg datetime/timestamp value from the database into a DateTime object value that Perl can use.
I really can’t seem to include code blocks in my posts on this platform (tried Preview with Markdown and Markdown With SmartyPants without success), so you can read the rest of this article on my blog.

Write a program which outputs one word of its own script / source code at random. A word is anything between whitespace, including symbols.
Example 1
If the source code contains a line such as: 'open my $fh, "<", "ch-1.pl" or die;'
then the program would output each of the words { open, my, $fh,, "<",, "ch-1.pl", or, die; }
(along with other words in the source) with some positive probability.
Example 2
Technically 'print(" hello ");' is *not* an example program, because it does not
assign positive probability to the other two words in the script.
It will never display print(" or ");
Example 3
Hi All! Given the number of talks submitted to this year's London Perl & Raku Workshop we have decided to reserve a third room in the venue. This will give us a bit more room on the schedule for talks, which is good as the other two rooms are now 90% full.
However, we would also like to use this third room for something else. Its capacity is relatively low, 15 people including the person presenting, so we feel it might be suitable for use as a breakout room / mini hackathon(s) / birds of a feather; and we will probably reserve two large slots for this. If you have an idea of something you'd like to use the room for then please get in touch with us.
Another way we can make more space for talks is to opt for lunch at the venue, this will free up space for three more talks. To do that we need a couple more sponsors so if you would like to help with that then please have a look at the options here: https://act.yapc.eu/lpw2024/sponsoring.html
