Unofficially and far more popularly, it's the camel. https://www.perl.org/camel.html
The raptor on the Github image may be familiar to other Mojolicious users, but I don't know why they're using it for the Perl team on Github.
This is great, thanks for organizing. I love community feedback especially now that the future of Perl is in discussion (e.g. Perl 7). That said, I'm slightly concerned about the ability of Perl Foundation to act on it. Just three weeks ago, they released the results of the developer survey where the community asked for better tooling and IDE support, and they responded with:
> There is already IDE support for Perl - but feedback in the survey shows that we need a page on https://www.perl.org/
They basically told the community that we're wrong, IDE support is already great, and we just need an info page.
Now 3 weeks later they're asking for community feedback again. How can I be sure this will result in meaningful and actionable outcomes toward the future of Perl? Or are we just providing input on an updated mission statement to drop on some website?

Formatting is absolute shit since I'm on phone. Download and install gnupg for windows if on Windows or if your in Linux it's probably installed if not install it with your package manager Download John the ripper from here. Download Perl from here (depending in your os you might have it pre-installed but if your in Windows download strawberry Perl.) Open cmd or terminal and write: gpg --receive-keys 05C027FD4BDC136E gpg --verify your-downloaded-john-signature.sign If it says that the signature is correct it should be ok. If not download John again. Ignore any error like public key not signed. Now do: 7z X your-compressed-john-binary.tar.gz 7z X your-compressed-john-binary.tar cd where-the-binaries-extracted cd the-only-folder-you-see cd run cpan install Exif::Tools perl pdf2john.pl name-of-your-encrypted-pdf.pdf > hashes_to_crack john hashes_to_crack It should start to crack. Keep in mind it will probably take a lot of time to crack the hash.
If you google for Perl certificate you'll find a number of sources. There was one company that tried to set up certification a number of years ago, and asked the community to comment on their questions. Opinion was unanimous that the questions were outdated, incorrect, or only partially true. I don't remember hearing from that company again.
Here's what Randal Schwartz thinks on the topic.
In my opinion, certificates tell a company that a candidate has some degree of competence at some drastically limited subset of the CS world. You have certificates in Visual Basic or C# because many companies use the technology, and they want employees that function as interchangeable, disposable units. Perl has a limited market; the best companies use Perl, but unfortunately not enough employers fit into that category. So there aren't a vast horde of applicants who have done a programming course, once, and employers have a little time to pay attention to the applicants capabilities.
Actually, there IS a globally recognized Perl certificate, it's called CPAN. Write a module and publish it. Or write an application and put it on GitHub. (search for legrady on github.com to find me). Or write blog articles about aspects of Perl, how it resembles or differs from other languages, about things you've figured out. Blogs.Perl.org is one place to do it, or you can announce a blog at your own location, via http://ironman.enlightenedperl.org/. Explore other resources at https://www.perl.org/community.html. There's also IRC; become a regular participant / contributor.
A good example of why it's sad that the White Camel Awards ended when brian stopped running them.
But I've seen a post from Wendy somewhere today pointing out that DHA made a huge number of commits to the Raku codebase - most of them in documentation.
Mohammad S. Anwar in this week's Perl Weekly reminded me of the list of past recipients of the White Camel Award. These are all people who have been recognized for their non-technical work for the Perl Community in the past.
https://www.perl.org/advocacy/white_camel/
Now ask yourself this:
- why hasn't there been a White Camel Award since 2018?
- how many of these people have left the Perl Community?
I'd say the majority of these people have left the Perl community either directly or indirectly because of the toxicity of certain members, Subject included.
"I object. 7-zip is a perfectly good free software that does everything WinRAR does, without complaining."
"There is always the camel alternative."
I thought for a long time. Then I wrote. Then I stood.
"God, I stand before you to defend my thesis:"
Implementing Perl in Lua: Passing a camel through the eye of a needle
To clarify, after some harassment, I didn't want to be the point person for the White Camel Awards anymore. I suggested that TPF find someone else or give them a new direction, but nothing came of that.
I really wanted to highlight the non-technical work that underpinned the community, but every year it because more about people pushing for recognition of technical work and trying to tear down the work of others in favor of their favorite thing.
David was awarded his White Camel in 2001. Years later he took over administration of the awards before I came back and give him a break.
> I for one plan to stay far away from attending or organizing any conference where TPF is involved, given this how they operate.
Do you have any idea how they operate? How much work has been done by people in the CAT team and on the TPF board to address these issues? How many people they have talked to?
I'd say: no, you don't.
Do you have suggestions for improvements? How it *should be done if it were up to you? Would you want to be a member of the CAT Team?*
I'd say: no, you don't.
So the Perl community should be a purely a "Lord of the Flies" thing? Everybody decides what they find acceptable, and if you disagree with that, you should just leave?
Well, I have news for you: many have already left because it is very much like "Lord of the Flies". And it pains me to say, as the recipient of the 2013 White Camel Award for Perl conferences that I have left the Perl community for the same reasons that are being discussed in the CAT report. There are only very few people in my life that I decided to not trust a word they say anymore: Subject is one of those few.
With regards to boycotting TPF: be careful what you wish for. At one point, everybody involved with TPF will have enough of it, as so many in the Perl community have.
And then who is going to organize just about anything, particularly in the US? The reason that TPF is organizing events is because there are no longer enough grassroots Perl users willing or able to organize Perl events. Think about that!
So, just saying "no" doesn't cut it. If you value the Perl community, you have to come up with something better. I have given up.
Hostility towards established learning technologies that aren't currently popular is a serious problem. The big push towards containers and orchestration technologies over the past decade or so has too often come at the opportunity cost of basic sysadmin skills.
Hint: a few lines of Perl shouldn't scare you and Linux from Scratch is your friend.
Perl 5 and Perl 6 are completely separate languages. On the (Perl)[https://www.perl.org] website, all the way down it, says, quote >"Perl 6 is a sister language, part of the Perl family, not intended as a replacement for Perl 5, but as its own thing - libraries exist to allow you to call Perl 5 code from Perl 6 programs and vice versa."
> There is already IDE support for Perl - but feedback in the survey shows that we need a page on https://www.perl.org/
This feels like a huge miss. The community provided feedback that IDEs are generally not that good with Perl, and their response was essentially "No, you're wrong; IDE support is great and you just don't know".
My suspicion is what you really need and want is computer programming. If so you can learn a great deal on your own and if you have a field you're familiar with, like economics, that can make you a good subject matter specialist for things you code or help code.
I work in medical IT support. We have people who have done IT for 30 years and an ex-nurse who has done IT for 6 months. The clinicians have more respect for the ex-nurse even though they may not really know as much about the program as the 30 year person.
I'd start with perl.

Even if you decide, "No CS is really what I want/NightMgr is wrong" it's a great starting language to help understand the concepts of programming that will help you if you decide CS is what you really want.
No real point paying for a Unity course - there are so many tutorials all over youtube, and Unity themselves have an entire section of their site full of tutorials covering a range of topics.
If it's coding in general you want to get used to, there are some great resources out there like beginning perl, which while technically specific to perl, gives a really good comprehensive understanding of general programming ideas. The other great resource I would share is Handmade Hero's first few streams, which go over the basics of C and explain how programming in general works, from a very basic level. If neither of these help you, there are countless other options as well, just gotta look for them - some are even linked in the sidebar.
Is the data in record-per-line format?
If so want to cut and paste an example line of text, and perhaps I can give you a Perl one-liner you could use to blank out the matched text?
Notice that it doesn't have to be Bash, though:
#!/bin/python
will call the Python interpreter (Python being arguably a better and easier to grok scripting language),
#!/bin/lua
will call the Lua interpreter, and
#!/bin/perl
will call the PERL interpreter.
There are hundreds of other open source languages you can use for your scripts, including PHP, JavaScript, what have you; and they will all work in more or less the same way.
not a course, there are these two free online books Beginning Perl , Modern Perl
which are both very good
You did violate the rule to ask a Perl 5 question in a Perl 6 subreddit.
Since you utterly fail at a very simple assignment I would like to recommend to abandon your teacher (as that person clearly doesn't know how to teach) and seek refuge at https://www.perl.org/learn.html .
Well, you might want to read a book like https://www.perl.org/books/beginning-perl/ (free legal download) to find out how to read a file.
The construction like $file = next if />/ doesn't really make sense. PERHAPS you mean something like
while (defined($line=<$file>)) { last unless $line=~/^>/; }
my @r = split(',',$line); return @r; }
Or something like that? It's hard to guess what you want to do since your description of the file format was vague.
Just by changing the identifier function I got a boost about 6x:
identifier => -> $v { $v[0] * $size[1] + $v[1] },
instead of doing stringification and join the two dimensions with a comma. Wow!
Still far from about 2 s in Perl though... with basically the same implementation. Or maybe not?
New to perl? Good Lord, sure you don't want to learn something easier, like JavaScript?
Look up wildcards, eg; instead of Filename.ext do *.ogg then research for, if else, continue..
and return
Also exit 0
Nutmeggers. 😒
Perl is just such a language. Text manipulation of this type is the fourth feature listed on the About Perl page, and is the first listed feature to reference a specific action:
>Text manipulation
>
>Perl includes powerful tools for processing text that make it ideal for working with HTML, XML, and all other mark-up and natural languages.
As a result, Perl substring uses method #2, so it is no surprise that languages inspired by Perl and employed for similar purposes do as well (PHP substr, et al).
I learned from here: https://www.perl.org/books/beginning-perl/
​
I worked exclusively in perl for about 2 years at a shared web hosting company.
​
I'd recommend learning Python tho.
I probably shouldn't have said "general use". What I meant was widespread use. You see python in games, scientific computing, etc. PHP doesn't get much use outside of web development. Part of this is historical; PHP sucked until 5.x. And part is cultural. PHP sucked so people didn't create libraries or promote it so it got pigenholed as a web thing which was always it's primary focus. Modern PHP is being condemned for old PHP's sins.
Python on the other had positioned itself to be a replacement for Perl ; the general purpose glue language that can do anything. And people used it as such; creating libraries and communities for just about anything you can possibly do with Python.
I'm not conflating the two. I'm using https://www.perl.org to mean "Perl" because that's what the domain name is. If there is a desire for "perl.org" to mean "Perl 5", perhaps perl.org should redirect to perl5.org? The website also says "Current Perl version" and not "Current Perl 5 version". I understand the messaging issue Perl 6 has but when even "perl.org" says the "Current Perl version" is Perl 5.x.x, why wouldn't people just think Perl is Perl 5?
Here's a script that will allow to calculate your average hashrate when ethminer produces variable hashrate results like:
miner 02:16:07.510|ethminer Mining on PoWhash #ad8608a0… : 20971520 H/s = 4194304 hashes / 0.2 s miner 02:16:07.711|ethminer Mining on PoWhash #ad8608a0… : 83468736 H/s = 16777216 hashes / 0.201 s miner 02:16:07.913|ethminer Mining on PoWhash #ad8608a0… : 41734368 H/s = 8388608 hashes / 0.201 s
This script will also print out your 'accept' and 'FAILURE: GPU gave incorrect results!' messages.
Works with Linux and Mac OS X. For Window you will have to download Perl from https://www.perl.org/get.html .
Example:
user@Kumquat:~$ calcHashrate logs/ethminer.log ℹ 21:24:12.221|ethminer B-) Submitted and accepted. ℹ 21:24:14.671|ethminer B-) Submitted and accepted. ℹ 21:24:17.519|ethminer B-) Submitted and accepted. ℹ 21:24:30.835|ethminer B-) Submitted and accepted. ✘ 18:11:00.367|ethminer FAILURE: GPU gave incorrect result! ✘ 18:41:12.725|ethminer FAILURE: GPU gave incorrect result! ✘ 20:03:32.135|ethminer FAILURE: GPU gave incorrect result! ✘ 20:23:53.048|ethminer FAILURE: GPU gave incorrect result! 21:25:04.239 62.619 MH/s
It's totally possible, but it depends on your learning style. Schools exist for a reason, and they'll almost certainly help you learn in some regard, but you may find it won't help you enough to make it worthwhile. There are also some really good tutorials out there in different forms, which arguably do as good a job.
I'd recommend reading Beginning Perl as a nice introduction to programming. It's specifically about perl, obviously, but it covers a lot of the important programming aspects of the style of languages usually used with games. Languages like Java, C#, Python - these all have fairly similar features and mindsets to Perl, and they're the kind of languages you'll mostly use for gamedev. The alternative is languages like C++, or even Objective-C for iOS stuff. They're a lot more rigid, which can be harder to deal with but it definitely reduces the bugs you could have in a working build - for example in Java, you create variables without saying what kind of data they hold, so you could give a variable some text at one point, then change it to a number later, and the language just does its best to figure out which one you want. Of course if it gets it wrong, it won't tell you, so you've got to find out where it went wrong. That said, C-type languages often end up being very finnicky, which is why C# is my favourite so far - fairly free, very little finnicking, but rigid enough to minimise dumb errors like that.
No, ActiveRecords is a pattern implemented with DBI, which has the insert, update, delete and related methods. DBIx::Class goes a step further and ties it up in a native data structure, so that writing to a variable updates the DB. DBIx::Class is an "object relational mapper" (ORM) . You don't need to call the database methods.
I've gotten away from programming and scripting since changing careers, but PowerShell is incredibly powerful. Obviously only in Windows environments. C# is probably my favorite programming language, but again, Windows only.
For platform agnostic use Java and Perl. I really like how Perl is run by it's developers and that there's an abundance of free learning material. Java is very splintered still, everyone keeps trying to make different frameworks for it and the Java industry hasn't agreed on just one, like c# has just .NET. So while Java is powerful, I find it to be unrefined.
Then there's the not oft talked about D.
