This year's London Perl and Raku Workshop is just 4 weeks away. We now have a pretty full schedule, so the call for presentations is now closed, however we might have room for one or two more talks depending circumstances on the day. If you really think you have talk you want to give then get in touch.
As part of the workshop we would like to ask attendees if any are willing to volunteer for helping out on the day. This will likely include:
Room monitoring and video equipment operation
Registration of attendees
General assistance of organisers and attendees
We are probably looking for three people to help out on the day. Please contact the organisers if you would like to help out.
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:
Spoiler Alert: This weekly challenge deadline is due in a few days from now (on September 22, 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.
Task 1: Strong Password
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.
We devised a strategy to deal with smartmatch, starting with reverting its removal. A separate email with details will follow.
We spent too much time talking about putting the apostrophe package separator behind a feature. That too will be outlined in a separate email. A github issue will follow.
We want to revert the open undef patch, for a variety of reasons, such as breaking autodie. We decided the steps to handle this.
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:

Task 2: Order Game
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.
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.

Task 1: Self Spammer
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 ");
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.

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.

Task 2: Making Change
Compute the number of ways to make change for given amount in cents. By using the coins e.g. Penny, Nickel, Dime, Quarter and Half-dollar, in how many distinct ways can the total value equal to the given amount? Order of coin selection does not matter.
A penny (P) is equal to 1 cent.
A nickel (N) is equal to 5 cents.
A dime (D) is equal to 10 cents.
A quarter (Q) is equal to 25 cents.
A half-dollar (HD) is equal to 50 cents.
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.

Task 2: Reverse Word
You are given a word, $word and a character, $char.
Write a script to replace the substring up to and including $char with its characters sorted alphabetically. If the $char doesn’t exist, then DON'T do anything.
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
