1. JavaScript for Interviews
This is my first post/blog/article of any sort, so any feedback will be appreciated.
These are my notes which I prepared to revise for JavaScript interviews. Some of the topics are advanced but are a must-know for a intermediate JavaScript developer.
💪 Basics
JavaScript is a dynamically typed language
Data type of variables can be changed during runtime
var justAVariable = 10;
justAVariable = "I am a string now";
/* Does not throw any error */
Variables
Scope
Can be updated?

2. Be pragmatic setting up CI for the RDF::KV
Today I tried to set up CI on GitHub Actions for the RDF::KV Perl module
that I found on CPAN Digger to be lacking CI.
It wasn't supposed to be difficult but I encountered some issues and had to be pragmatic in the setup even if far from ideal.
IMHO it is better to have a working CI that already checks part of what can be checked than to have nothing.
I cloned the Git repository of the package and as it came with a Makefile.PL I ran the usual
perl Makefile.PL
just to see a nasty error:

3. El humor en sistemas
Si dijera que paso un día sin mirar el lado divertido de mi profesión, les estaría mintiendo. Hoy los voy a meter de lleno en el humor de los programadores y cómo entenderlo.
Hablando con mucha gente por ahí, aprendí algo interesante: La gente se siente más motivada a aprender algo cuando hay humor de por medio.
Si te sentás a una mesa donde todos están haciendo chistes sobre algo, querés integrarte, entenderlo y reírte con ellos. Pero no todo el humor es sencillo de entender a la primera.

1. Day 9: CI for Mojo-UserAgent-Cached and Plack-Middleware-Greylist
Today I can report about two pull-requests for two web-related Perl projects.
One of them is called Mojo-UserAgent-Cached and the other one is Plack-Middleware-Greylist.
Mojo-UserAgent-Cached
It was quite straight-forward. There were only two small issues.
I had to install Module::Install before I could use the regular tools
as the Makefile.PL relies on that. That's a known drawback of Module::Install for developers and maintainers.

1. A Perl Pattern for Read-Only Configuration Access
Some programs have many subroutines that need access to some read-only configuration. Deciding how to provide access to this configuration in a safe way, that ensures no mutation will take place, is important to the reliability of the program.
The simplest thing to do is to use a global variable. The problem with using a global variable is that you have to be careful to not mutate it, or else your program may behave mysteriously. If you trust yourself not to mess up, then using a global variabl…

It’s the 23rd day of Makuake Advent Calendar 2022 .
As we know OpenTelemetry is an observability framework to generate and export telemetry data. As more companies adopt microservices and SLI/SLOs, we need it to answer new, never-before-seen (and complex) questions.
In that context, observability of systems that communicate using asynchronous messaging is as important as systems communicates using synchronous messagin like HTTP or gRPC.

2. Jenkins for running scripts!
I have over 30 scripts that are used to pull data and push data between different services. Its critical to know when they fail. Sure you could do this with cron but then I looked around and saw that Jenkins could run scripts, console output log, and emails me on fails.
After you have set up jenkins and set up the email settings.

1. Thank you dev.to!
Hey dev.to community,
I just wanted to say a big thank you to the dev.to team for the gift you sent me over the holidays. I just received it in the mail. The card is awesome (and there is a shiny sticker)!
It was such a cool surprise and it really made my day. I'm so appreciative of the recognition for my contributions over the past year (top author 2022, wow).
Thank you dev.to for the effort and attention that you put towards the authors and contributors, and for all the nice additions you g…

1. one-liner: read first elements of a huge directory
At a client we have a networked disk with millions of files. I was trying to list the first few files to see what's going on.
ls -l | head takes ages, but here is a Perl one-liner to make it work:
perl -E 'opendir(my $dh, "/huge_dir"); my $c = 0; while (my $d = readdir($dh)) { say $d; exit if ++$c > 3 }'
In a different layout that could be put in a file
use feature 'say';
opendir(my $dh, "/huge_dir");
my $c = 0;
while (my $d = readdir($dh)) {
say $d;
exit if ++$c > 3
}

3. Deploying a Laravel App on AWS App Runner
Deploying a containerized app gets easier everyday as cloud providers release new products. One of such products by AWS is AWS App Runner.
AWS App Runner is a fully managed container application service that lets you build, deploy, and run containerized web applications and API services without prior infrastructure or container experience.
Ever want to just deploy an app without the Kubernetes or complex networking overhead? Or have a couple of services to maintain without alot of configuratio…

1. Zero byte apple-touch-icon markup
*This is part of a series of pieces about code you can safely remove from the tags of your website.
You can read the rest here: getoutofmyhead.dev*
An apple-touch-icon is an image used on iOS devices when a website is added to the homescreen.
Different iOS devices display icons at different sizes, and so it's common to see something like this:
rel="apple-touch-icon" sizes="152x152" href="https://assets.guim.co.uk/images/favicons/fee5e2d638d1c35f6d501fa397e53329/152x152.png"/>

2. Perl Weekly #601 - The bad apple
Originally published at Perl Weekly 601
Welcome to the Perl Weekly!
I am ambivalent about writing this and including in the Perl Weekly, but I feel if I don't speak up then how can expect others to do so.
For another perspective on the subject I'd recommend you read this thread by Mohammed Hashim on trust and perspective.
A couple of weeks ago I received an email full of good old antisemitism. It was clearly indicating that it is from one of the readers of the Perl Weekly. It was a tirade of…

1. The K-Nearest Neighbors Algorithm for regression and classification
K-nearest neighbors (KNN) is a supervised learning algorithm used for classification and regression. The algorithm works by finding the k closest data points (neighbors) to a given test data point and making a prediction based on their labels/values. The prediction is typically the average (for regression) or the majority class label (for classification) among the k nearest neighbors.
In mathematical terms, KNN is a non-parametric method. Given a training dataset of N labeled points in a d-dime…

2. US government agencies' opensource projects
1st OSDC pull request
I have been interested in the US government opensource activities since around 2016, so all my OSDC homework entries of the open source projects are in the governments section.
The most interesting project would be ghidra.
Back in 2018 I was looking for a reverse compiling tool to look at the binary of Dominions 5 (it is a play by email 4X game. lots of fun!). IDA pro is really nice but I do not have the budget to purchase a license.
