-Here are some Perl Poems I wrote. They don't do anything useful when you run them, but they don't produce a compiler error either. They only exist for fun and demonstrate what you can do with Perl syntax.

-Wikipedia: "Perl poetry is the practice of writing poems that can be compiled as legal Perl code, for example the piece known as Black Perl. Perl poetry is made possible by the large number of English words that are used in the Perl language. New poems are regularly submitted to the community at PerlMonks."

-Have you reached this article already via Gemini? It requires a Gemini client; web browsers such as Firefox, Chrome, Safari, etc., don't support the Gemini protocol. The Gemini address of this site (or the address of this capsule as people say in Geminispace) is:

-## Motivation
-
-### My urge to revamp my personal website
-
-For some time, I had to urge to revamp my personal website. Not to update the technology and its design but to update all the content (+ keep it current) and start a small tech blog again. So unconsciously, I began to search for an excellent platform to do all of that in a KISS (keep it simple & stupid) way.
-
-### My still great Laptop running hot
-
-Earlier this year (2021), I noticed that my almost seven-year-old but still great Laptop started to become hot and slowed down while surfing the web. Also, the Laptop's fan became quite noisy. This was all due to the additional bloat such as JavaScript, excessive use of CSS, tracking cookies+pixels, ads, and so on there was on the website. 
-
-All I wanted was to read an interesting article, but after a big advertising pop-up banner appeared and made everything worse, I gave up and closed the browser tab.
-
-## Discovering the Gemini internet protocol
-
-Around the same time, I discovered a relatively new, more lightweight protocol named Gemini, which does not support all these CPU-intensive features like HTML, JavaScript, and CSS. Also, tracking and ads are unsupported by the Gemini protocol.

 Why is there a need for a new protocol? As the modern web is a superset of Gemini, can't we use simple HTML 1.0 instead? That's a good and valid question. It is not a technical problem but a human problem. We tend to abuse the features once they are available. You can ensure that things stay efficient and straightforward as long as you are using the Gemini protocol. On the other hand, you can't force every website on the modern web to only create plain and straightforward-looking HTML pages.

 You should learn or try out one new programming language once yearly anyway. If you end up not using the new language, that's not a problem. You will learn new techniques with each new programming language and this also helps you to improve your overall programming skills even for other languages.

-When I was a Linux System Administrator, I have been programming in Perl for years. I still maintain some personal Perl programming projects (e.g. Xerl, guprecords, Loadbars). After switching jobs a couple of years ago (becoming a Site Reliability Engineer), I found Ruby (and some Python) widely used there. As I wanted to do something new, I decided to give Ruby a go.

 Superficially, Perl seems to have many similarities to Ruby (but, of course, it is entirely different to Perl when you look closer), which pushed me towards Ruby instead of Python. I have tried Python a couple of times before, and I managed to write good code, but I never felt satisfied with the language. I didn't love the syntax, especially the indentations used; they always confused me. I don't dislike Python, but I don't prefer to program in it if I have a choice, especially when there are more propelling alternatives available. Personally, it's so much more fun to program in Ruby than in Python.

-A robust computer system must be kept simple and stupid (KISS). The fancier the system is, the more can break. Unfortunately, most systems tend to become complex and challenging to maintain in today's world. In the early days, so I was told, engineers understood every part of the system, but nowadays, we see more of the "lasagna" stack. One layer or framework is built on top of another layer, and in the end, nobody has got a clue what's going on.
-
-# Need faster hardware
-
-This not just makes the system much more complex, difficult to maintain and challenging to troubleshoot, but also slow. So more experts are needed to support it. Also, newer and faster hardware is required to make it run smoothly. Often, it's so much easier to buy speedier hardware than rewrite a whole system from scratch from the bottom-up. The latter would require much more resources in the short run, but in the long run, it should pay off. Unfortunately, many project owners scare away from it as they only want to get their project done and then move on.

-I have recently released DTail 4.0.0 and this blog post goes through all the new goodies. If you want to jump directly to DTail, do it here (there are nice animated gifs which demonstrates the usage pretty well):
-
-[https://dtail.dev](https://dtail.dev)  
-
-## So, what's new in 4.0.0?
-
-### Rewritten logging
-
-For DTail 4, logging has been completely rewritten. The new package name is "internal/io/dlog". I rewrote the logging because DTail is a special case here: There are logs processed by DTail, there are logs produced by the DTail server itself, there are logs produced by a DTail client itself, there are logs only logged by a DTail client, there are logs only logged by the DTail server, and there are logs logged by both, server and client. There are also different logging levels and outputs involved.
-
-As you can imagine, it becomes fairly complex. There is no ready Go off-shelf logging library which suits my needs and the logging code in DTail 3 was just one big source code file with global variables and it wasn't sustainable to maintain anymore. So why not rewrite it for profit and fun? 
-
-There's a are new log level structure now (The log level now can be specified with the "-logLevel" command line flag):
-
-```
-// Available log levels.
-const (
-	None    level = iota
-	Fatal   level = iota
-	Error   level = iota
-	Warn    level = iota
-	Info    level = iota
-	Default level = iota
-	Verbose level = iota
-	Debug   level = iota
-	Devel   level = iota
-	Trace   level = iota
-	All     level = iota
-)
-```
-
-DTail also supports multiple log outputs (e.g. to file or to stdout). More are now easily pluggable with the new logging package. The output can also be "enriched" (default) or "plain" (read more about that further below).
-
-### Configurable terminal color codes
-
-A complaint I received from the users of DTail 3 were the terminal colors used for the output. Under some circumstances (terminal configuration) it made the output difficult to read so that users defaulted to "--noColor" (disabling colored output completely). I toke it by heart and also rewrote the color handling. It's now possible to configure the foreground and background colors and an attribute (e.g. dim, bold, ...).
-
-The example "dtail.json" configuration file represents the default (now, more reasonable default) color codes used, and it is free to the user to customize them:
-
-```

-
-You notice the different sections - these are different contexts:
-
-* Remote: Color configuration for all log lines sent remotely from the server to the client. 
-* Client: Color configuration for all lines produced by a DTail client by itself (e.g. status information).
-* Server: Color configuration for all lines produced by the DTail server by itself and sent to the client (e.g. server warnings or errors)
-* MaprTable: Color configuration for the map-reduce table output.
-* Common: Common color configuration used in various places (e.g. when it's not clear what's the current context of a line).
-
-When you do so, make sure that you check your "dtail.json" against the JSON schema file. This is to ensure that you don't configure an invalid color accidentally (requires "jsonschema" to be installed on your computer). Furthermore, the schema file is also a good reference for all possible colors available:
-
-```
-jsonschema -i dtail.json schemas/dtail.schema.json
-```
-
-### Serverless mode
-
-All DTail commands can now operate on log files (and other text files) directly without any DTail server running. So there isn't a need anymore to install a DTail server when you are on the target server already anyway, like the following example shows:
-
-```
-% dtail --files /var/log/foo.log
-```
-
-or
-
-```
-% dmap --files /var/log/foo.log --query 'from TABLE select .... outfile result.csv'
-```
-
-The way it works in Go code is that a connection to a server is managed through an interface and in serverless mode DTail calls through that interface to the server code directly without any TCP/IP and SSH connection made in the background. This means, that the binaries are a bit larger (also ship with the code which normally would be executed by the server) but the increase of binary size is not much.
-
-### Shorthand flags
-
-The "--files" from the previous example is now redundant. As a shorthand, It is now possible to do the following instead:
-
-```
-% dtail /var/log/foo.log
-```
-
-Of course, this also works with all other DTail client commands (dgrep, dcat, ... etc).
-
-### Spartan (aka plain) mode
-
-There's a plain mode, which makes DTail only print out the "plain" text of the files operated on (without any DTail specific enriched output). E.g.:
-
-```
-% dcat --plain /etc/passwd > /etc/test
-% diff /etc/test /etc/passwd  # Same content, no diff
-```
-
-This might be useful if you wanted to post-process the output. 
-
-### Standard input pipe
-
-In serverless mode, you might want to process your data in a pipeline. You can do that now too through an input pipe:
-
-```
-% dgrep --plain --regex 'somethingspecial' /var/log/foo.log |
-    dmap --query 'from TABLE select .... outfile result.csv'
-```
-
-Or, use any other "standard" tool:
-
-```
-% awk '.....' < /some/file | dtail ....
-```
-
-### New command dtailhealth
-
-Prior to DTail 4, there was a flag for the "dtail" command to check the health of a remote DTail server (for use with monitoring system such as Nagios). That has been moved out to a separate binary to reduce complexity of the "dtail" command. The following checks whether DTail is operational on the current machine (you could also check a remote instance of DTail server, just adjust the server address).
-
-```
-% cat check_dtail.sh
-#!/bin/sh
-
-exec /usr/local/bin/dtailhealth --server localhost:2222
-```
-
-### Improved documentation
-
-Some features, such as custom log formats and the map-reduce query language, are now documented. Also, the examples have been updated to reflect the new features added. This also includes the new animated example Gifs (plus documentation how they were created).
-
-I must admit that not all features are documented yet:
-
-* Server side scheduled map-reduce queries
-* Server side continuous map-reduce queries
-* Some more docs about terminal color customization
-* Some more docs about log levels
-
-That will be added in one of the future releases. 
-
-### Integration testing suite
-
-DTail comes already with some unit tests, but what's new is a full integration testing suite which covers all common use cases of all the commands (dtail, dcat, dgrep, dmap) with a server backend and also in serverless mode.
-
-How are the tests implemented? All integration tests are simply unit tests in the "./integrationtests" folder. They must be explicitly activated with:
-
-```
-% export DTAIL_INTEGRATION_TEST_RUN_MODE=yes
-```
-
-Once done, first compile all commands, and then run the integration tests:
-
-```
-% make
-.
-.
-.
-% go clean -testcache
-% go test -race -v ./integrationtests
-```
-
-### Improved code
-
-Not that the code quality of DTail has been bad (I have been using Go vet and Go lint for previous releases and will keep using these), but this time I had new tools (such as SonarQube and BlackDuck) in my arsenal to:
-
-* Reduce the complexity of a couple of functions (splitting code up into several smaller functions)
-* Avoid repeating code (this version of DTail doesn't use Go generics yet, though).
-
-Other than that, a lot of other code has been refactored as I saw fit.
-
-### Use of memory pools
-
-DTail makes excessive use of string builder and byte buffer objects. For performance reasons, those are now re-used from memory pools.
-
-## What's next
-
-DTail 5 won't be released any time soon I guess, but some 4.x.y releases will follow this year fore sure. I can think of:
-
-* New (but backwards compatible) features which don't require a new major version bump (some features have been requested at work internally).
-* Even more improved documentation.
-* Dependency updates.
-
-I use usually DTail at work, but I have recently installed it on my personal OpenBSD machines too. I might write a small tutorial here (and I might also add the rc scripts as examples to one of the next DTail releases).
-
-I am a bit busy at the moment with two other pet projects of mine (one internal work-project, and one personal one, the latter you will read about in the next couple of months). If you have ideas (or even a patch), then please don't hesitate to contact me (either via E-Mail or a request at GitHub).

-Perl (the Practical Extraction and Report Language) is a battle-tested, mature, multi-paradigm dynamic programming language. Note that it's not called PERL, neither P.E.R.L. nor Pearl. "Perl" is the name of the language and `perl` the name of the interpreter or the interpreter command.
-
-Unfortunately (it makes me sad), Perl's popularity has been declining over the last years as Google trends shows:

-
-So why is that? Once the de-facto standard super-glue language for the web nowadays seems to have a bad reputation. Often, people state:
-
-* Perl is a write-only language. Nobody can read Perl code.
-* Perl? Isn't it abandoned? It's still at version 5!
-* Why use Perl as there are better alternatives?
-* Why all the sigils? It looks like an exploding ASCII factory!!
-
-## Write-only language
-
-Is Perl really a write-only language? You have to understand that Perl 5 was released in 1994 (28 years ago as of this writing) and when we refer to Perl we usually mean Perl 5. That's many years, and there are many old scripts not following the modern Perl best practices (as they didn't exist yet). So yes, legacy scripts may be difficult to read. Japanese may be difficult to read too if you don't know Japanese, though.
-
-To come back to the question: Is Perl a write-only language? I don't think so. Like in any other language, you have to apply best practices in order to keep your code maintainable. Some other programming languages enforce best practices, but that makes these languages less expressive. Perl follows the principles "there is more than one way to do it" (aka TIMTOWDI) and "making easy things easy and hard things possible".
-
-Perl gives the programmer more flexibility in how to do things, and this results in a stronger learning curve than for lesser expressive languages like for example Go or Python. But, like in everything in life, common sense has to be applied. You should not take TIMTOWDI to the extreme in a production piece of code. In my personal opinion, it is also more satisfying to program in an expressive language.

-
-It has been around a year since I released the first version `1.0.0`. Although, there aren't any groundbreaking changes, there have been a couple of smaller commits and adjustments. I was quite surprised that I received a bunch of feedback and requests about Gemtexter so it means that I am not the only person in the universe actually using it.
-
-## What's new?
-
-### Automatic check for GNU version requirements
-
-Gemtexter relies on the GNU versions of the tools `grep`, `sed` and `date` and it also requires the Bash shell in version 5 at least. That's now done in the `check_dependencies()` function:
-
-```bash
-check_dependencies () {
-    # At least, Bash 5 is required
-    local -i required_version=5
-    IFS=. read -ra version <<< "$BASH_VERSION"
-    if [ "${version[0]}" -lt $required_version ]; then
-        log ERROR "ERROR, \"bash\" must be at least at major version $required_version!"
-        exit 2
-    fi
-
-    # These must be the GNU versions of the commands
-    for tool in $DATE $SED $GREP; do
-        if ! $tool --version | grep -q GNU; then
-            log ERROR "ERROR, \"$tool\" command is not the GNU version, please install!"
-            exit 2
-        fi
-    done
-}
-```
-
-Especially macOS users didn't read the `README` carefully enough to install GNU Grep, GNU Sed and GNU Date before using Gemtexter.
-
-### Backticks now produce `inline code blocks` in the HTML output
-
-The Gemtext format doesn't support inline code blocks, but Gemtexter now produces `inline code blocks` (means, small code fragments can be placed in the middle of a paragraph) in the HTML output when the code block is enclosed with Backticks. There were no adjustments required for the Markdown output format, because Markdown supports it already out of the box.
-
-### Cache for Atom feed generation
-
-The Bash is not the most performant language. Gemtexter already takes a couple of seconds only to generate the Atom feed for around two hand full of articles on my slightly underpowered Surface Go 2 Linux tablet. Therefore, I introduced a cache, so that subsequent Atom feed generation runs finish much quicker. The cache uses a checksum of the Gemtext `.gmi` file to decide whether anything of the content has changed or not.
-
-### Input filter support
-
-Once your capsule reaches a certain size, it can become annoying to re-generate everything if you only want to preview the HTML or Markdown output of one single content file. The following will add a filter to only generate the files matching a regular expression:
-
-```sh
-./gemtexter --generate '.*hello.*'
-```
-
-### Revamped `git` support
-
-The Git support has been completely rewritten. It's now more reliable and faster too. Have a look at the `README` for more information.
-
-### Addition of `htmlextras` and web font support
-
-The `htmlextras` folder now contains all extra files required for the HTML output format such as cascading style sheet (CSS) files and web fonts.
-
-### Sub-section support
-
-It's now possible to define sub-sections within a Gemtexter capsule. For the HTML output, each sub-section can use its own CSS and web font definitions. E.g.:
-
-[The foo.zone main site](https://foo.zone)  
-[The notes sub-section (with different fonts)](https://foo.zone/notes)  
-
-### More
-
-Additionally, there were a couple of bug fixes, refactorings and overall improvements in the documentation made. 
-
-Overall I think it's a pretty solid `1.1.0` release without anything groundbreaking (therefore no major version jump). But I am happy about it.

- In this post, I want to give a quick overview (or how-to) about installing DTail on OpenBSD, as the official documentation only covers Red Hat and Fedora Linux! And this blog post will also be used as my reference!

+"The obstacle is the way" is a powerful statement that encapsulates the wisdom of turning challenges into opportunities for growth and success. We will explore using obstacles as fuel, transforming weaknesses into strengths, and adopting a mindset that allows us to be creative and persistent in the face of adversity.
+
+## Reframe your perspective
+
+The obstacle in your path can become your path to success. Instead of being paralyzed by challenges, see them as opportunities to learn and grow. Remember, the things that hurt us often instruct us. 
+
+We spend a lot of time trying to get things perfect and look at the rules, but what matters is that it works; it doesn't need to be after the book. Focus on results rather than on beautiful methods. In Jujitsu, it does matter that you bring your opponent down, but not how. There are many ways from point A to point B; it doesn't need to be a straight line. So many try to find the best solution but need to catch up on what is in Infront of them. Think progress and not perfection.
+
+Don't always try to use the front door; a backdoor could open. It's nonsense. Don't fight the judo master with judo. Non-action can be action, exposing the weaknesses of others.
+
+
+## Embrace rationality
+
+It is a superpower to see things rationally when others are fearful. Focus on the reality of the situation without letting emotions, such as anger, cloud your judgment. This ability will enable you to make better decisions in adversity. Ability to see things what they really are. E.g. wine is old fermented grapes, or other people behaving like animals while having sex. Show the middle finger if someone persists on the stupid rules occasionally.
+
+## Control your response
+
+You can choose how you respond to obstacles. Focus on what you can control, and don't let yourself feel harmed by external circumstances. Remember, you decide how things affect you; nobody else does. Choose to feel good in response to any situation. Embrace the challenges and obstacles that come your way, as they are opportunities for growth and learning.
+
+## Practice emotional and physical resilience
+
+Martial artists know the importance of developing physical and emotional strength. Cultivate the art of not panicking; it will help you avoid making mistakes during high-pressure situations.
+
+Focus on what you can control. Don't choose to feel harmed, and then you won't be harmed. I decide things that affect me; nobody else does. E.g., in prison, your mind stays your own. Don't ignore fear but explain it away, have a different view.
+
+## Persistence and patience
+
+Practice persistence and patience in your pursuits. Focus on the process rather than the prize and take one step at a time. Remember, the journey is about finishing tasks, projects, or workouts to the best of your ability. Never be in a hurry and never be desperate. There is no reason to be rushed; there are all in the long haul. Follow the process and not the price. Take it one step at a time. The process is about finishing (workout, task, project, etc.).
+
+## Embrace failure
+
+Failure is a natural part of life and can make us stronger. Treat defeat as a stepping stone to success and education. What is defeat? The first step to education. Failure makes you stronger. If we do our best, we can be proud of it, regardless of the result. Do your job, but do it right. Only an asshole thinks he is too good at the things he does. Also, asking for forgiveness is easier than asking for permission. 
+
+## Be adaptable
+
+There are many ways to achieve your goals; sometimes, unconventional methods are necessary. Feel free to break the rules or go off the beaten path if it will lead to better results. Transform weaknesses into strengths. We have a choice of how to respond to things. It's not about being positive but to be creative. Aim high, but stuff will happen; E.g., surprises will always happen.
+
+## Embrace non-action
+
+We constantly push to the next thing. Sometimes the best course of action is standing still or even going backwards. Obstacles might resolve by themselves. Or going sideways. Sometimes, the best action is to stand still, go sideways, or even go backwards. Obstacles may resolve themselves or present new opportunities if you're patient and observant. People always want your input before you have all the facts. They want you to play after their rules. The question is, do you let them? The English call it the cool head. Being in control of Stress; requires practice. Appear, the absence of fear (Greek). When all others do it one way, it does not mean it is the correct or best practice.
+
+## Leverage crisis
+
+In times of crisis, seize the chance to do things never done before. Great people use negative situations to their advantage and become the most effective in challenging circumstances.
+
+The art of not panicking; otherwise, you will make mistakes. When overs are shocked, you know which way to take due to your thinking of the problem at Hand. A crisis gives you a chance to do things which never done before. Ordinary people shy from negative situations; great people use these for their benefit and are the most effective. The obstacle is not just turned upside down but used as a catapult.
+
+Be prepared for nothing to work. Problems are an opportunity to do your best, not to do miracles. Always manage your expectations. It will suck, but it will be ok. Build your inner citadel. In good times strengthen it. In bad times rely on it. We should always prepare for things to get tough. Your house burns down: no worries, we eliminated much rubbish. Imagine what can go wrong before things go wrong. We are prepared for adversity; it's other people who aren't. Phil Jackson's hip problem example. To receive unexpected benefits, you must first accept the unexpected obstacles. Meditate on death. It's a universal obstacle. Use it as a reminder to do your best.
+
+Be prepared to begin from the beginning. Be cheerful and eagerly work on the next obstacle. Each time you become better. Life is not a sprint but a marathon. After each obstacle lies another obstacle, there won't be anything without obstacles. Passing one means you are ready for the next.
+
+## Build your inner citadel
+
+Develop your inner strength during good times so you can rely on it in bad times. Always prepare for adversity and face it with calmness and resilience. Maybe reconsider what you really desire. Be humble enough that things which happen will happen. 
+
+## Love everything that happens
+
+Turn an obstacle the other way around for your benefit. Use it at fuel. It's simple but challenging. Most are paralyzed instead. The obstacle in the path becomes the path. Obstacles are neither good nor bad. The things which hurt, instruct.
+
+Should I hate people who hate me? That's their problem and not mine. Be always calm and relaxed during the fight. The story of the battle is the story of the smile. Cheerfulness in all situations, especially the bad ones. Love for everything that happens; if it happens, it was meant to happen. We can choose how we react to things, so why not choose to feel good? I love everything that happens. You must never lower yourself to the person you don't like.
+
+## Conclusion
+
+Life is a marathon, not a sprint. Each obstacle we overcome prepares us for the next one. Remember, the obstacle is not just a barrier to be turned upside down; it can also be used as a catapult to propel us forward. By embracing challenges and using them as opportunities for growth, we become stronger, more adaptable, and, ultimately, more successful.
