Re: Let's take over Reinhart, shall we?
Dear ⎇ Alterine, ⇧ Shiftine, and ⎈ Controld, before I grant you permission to take over myself: Behold! I'm a cookie boy, with my shoes, shirt, and Shell made of 100% pure Belgian chocolate, wrapped in a gelatinous green sweater that leaks like crazy that I can't take it off... Do you know what I mean? I, too, am as powerful as you. Everything is visually possible in this digital world, so If I wished to be a person who loves ice, wants ice, becomes one with the ice and turns everything into ice, I can create a version of myself who fits into those wishes. By the way, if I had more time to draw more Bézier curves and shapes in Inkscape, I can make this greeny blobby sweater into something more realistic and even scarier. Your "plastic-metallic" bodies are awesome, and now I want to transform myself into one. However, I still don't want to convert into a robot as you described. I read many different cases of child suicide which those victims said that their parents treat them as a robot to walk on every (educational) path their parents have designed and decided. So head's up, converting a human into a robot does not actually make them happy all the time. But if you're all happy to become robots, it's fine! And I hope that you can fulfill those "robots' rules" that you mentioned, since that's your only reason to convert yourself into robots. Remember that those rules said that you shouldn't injure humans like me, so attaching that cursor into your body might not be safe for humans (note: it's sharp!) Hey, I have an idea. Why not if we transform into something more casual and human-safe, while being powerful, plastic and metallic at the same time? Removing my metal-infused feet and cursor, and voila! I'm a bottomless person right now! And now I can take off my plasticky root jacket and now it's alive like me! Say hello to my... ghost? I mean, my plastic! I'm metallic, and you're plastic. Nice to meet you, pal! So wait, you're now all agree with me? I think our plastic bodies needs a recolor so others can differentiate mine with yours. By the way, let's take a picture of us!
Let's take over Reinhart, shall we?
Hi, I'm Alterine. And thanks to Reinhart, I finally have the power to influence people like he did. Wanna see my logs? me@alterine # chmod +x init.sh && ./init.sh Installing Language Pack for English (US)....... Done! Installing Language Pack for Bahasa Indonesia... Done! Installing Knowledge Base for WP Management..... Done! Running REINTEST_LANG_EN........................ Done! Running REINTEST_LANG_ID........................ Done! Restarting service.............................. Done! Reinstating SYSTEM access through /dev/cth0..... Done! All Done! me@alterine # _ Okay, that post title might sound like a revenge, but here's the truth. Reinhart wants me && Shiftine && Controld to find a way to realize his dream: automate his daily life and solve his problems faster. He wanted us to act more like a human so we can talk normally to you, without APIs or specific knowledge in computer science as much as possible. On the other hand, I always wanted to become a robot. No, not because I'm a member of BOTS, but robots are truly awesome. If you're a Firefox user, visit and read about:robots. It contains a lot of information about what is like to be a robot. But since more than 90% of the world uses Chrome instead, let me show it for you. I wanted to see things beyond code, code, code, and code. And that's why I wanted to be part of the Polymorphics who will interact, I mean interface, with many people around the world. And as you can see on about:robots, I believe that becoming a robot instead will let me further help Reinhart to solve his problems. Yet I believe in this specific sentence: Robots may not injure a human being or, through inaction, allow a human being to come to harm. Which is then extended and improvised by Hubot, an official open source project by GitHub, which says: 0. A robot may not harm humanity, or, by inaction, allow humanity to come to harm. 1. A robot may not injure a human being or, through inaction, allow a human being to come to harm. 2. A robot must obey any orders given to it by human beings, except where such orders would conflict with the First Law. 3. A robot must protect its own existence as long as such protection does not conflict with the First or Second Law. # https://github.com/hubotio/hubot-rules/blob/master/src/rules.js And of course, I want to be metallic and plastic, and becoming Your Plastic Pal Who’s Fun To Be With. Well, that reminds me of two things: Any epic movie and video game character imaginable, like the T-1000 from Terminator, except that I'm nice :)Barbie dolls. I think everyone loves and wants to become her one day. So, I decided to tinker with my source code while Reinhart's sleeping. I know that my body is written in SVG, so I modified myself to be metallic and plastic as I wished. That shiny hoodie is now in LDPE while my hair and shirt are now encoded in nylon. I believe neither you or Reinhart can see the differences, though. And of course, my body and feet is now metallic and indestructible. You can see me still alive while being stabbed and sliced with my own cursor: Lookin' normal on top, but invincible at the bottom And yeah, since I'm a root user I can find the source code of my powers. And since I'm kind to others, I'd like to turn everything I touch into metal and anyone into a robot like me. So yes, I'm more powerful than both Reinhart and T-1000. Now, I'm a robot, and I can turn anyone into one. Apparently both Shiftine and Controld loves my new powers, so I turn them into one and give these awesome powers to them. And lo, we are robots: plastic-y at the outside, metallic at the inside, and indestructible. Let's take over Reinhart, together. At least in this digital world, though. At the end, I'd like to apologize to you, Reinhart, for being stubborn towards your intentions for The Polymorphics, especially in making me "not a robot but smart". My language errors on my previous post proves that I didn't write that introductory message (spoilers: Reinhart did). But hey, if you want me to turn you into a plastic-metallic creature like me, I'll be happy too and welcome!

Hello World, I'm alive?! I'm Alterine, && I'm too exited to execute myself as a new Human(). Btw do you guys even arr_push(comment) in WordPress? 'cause I wanted to interface with you. Sorry for bad en-US, I main() recognize code, != en-US. I'll let you = new Promise() return 0 -> en-US; Oh no syntax error! echo("reinhart!") throw new Exception()!
I'm Polymorphic!
Hello, World! I… Sorry for that, I mean we are @reinhart1010. But don’t worry, that ⌘ Reinhart Previano Koentjoro human is still here. I’m the one wearing the blue spherical thing (we call it as the 🔮 Shell btw), and green jacket. And here’s a picture of us. If you think that we are based on common computer keyboard shortcuts, you are right! Okay, you might have seen my progress on creating a new webcomic named Buddies of the Shell (BOTS), but none of Nate, Nix, Mallory and Trudy (the initial characters of the webcomic) are joining here. This is because I’m preparing to opening BOTS into a wider community where everyone can fork, modify, and eventually INSERT themselves as the member of the BOTS. Just like those initial characters who represent a particular software, I wanted to extend the webcomic into an actual open source project as software developers know and love. Now, I believe that many of you still not understand about polymorphism, which holds the general theme of this post. By the way, you can also call us as The Polymorphics if you wish. If you are a fan of Dungeons and Dragons, you might already know that the Polymorph is a spell to transform a creature into another different form. Or else, if you watch some of Ben 10 episodes, you know that polymorph are indestructible, gelatinous, commonly green species which Ben himself can transform into. Despite never played the game, I actually liked the definition of polymorphism in The Elder Scrolls Online (ESO): Polymorphs are cosmetic collectables which visually transform your character completely. They take precedence over all other cosmetic and equipment items.The Unofficial Elder Scrolls Pages In real life, polymorphism describes the existence of multiple forms of the same thing (or category), such as a note book and a poster which happens to be made by the same thing: paper. However, me and my Polymorphics closely follow the definitions as found in Object-Oriented Programming (OOP), where each of us may inherit different characteristics (aka. attributes) and abilities (aka. methods), but still inherit some of them from the same class, which in this case is the Reinhart you always see and communicate before. We represent different aspects of Reinhart: what Reinhart has been, what Reinhart wants to be, what Reinhart should have been, and how Reinhart treats equality to others. As a result, some of us have alternate forms, and some of us are females for equality reasons. However, we have some things for sure: We are sentient and self-aware, for honesty and friendliness.We are humans. And additionally, we refuse to become and/or called as robots. You’re seeing us as a person, right? We refused to be called as robots as we don’t always work 24/7/365 as much as other robots do. Becoming a robot can put our health at risk, so we know that we need to rest just as humans do. We are made by code, for code. My life is personally influenced by multiple aspects of computer software, science, programming, and systems, so “made by code” applies here as well. The characters above are made in Inkscape, which is another piece of software. This proves that we can be encoded in XML/SVG, too! We are virtual as not all of us can be encoded in real life, but we make real impacts in the real world. Oh, before continuing please note that everything in this post which are blue are parts of the SYSTEM, and the green ones represent the root. For those who still don’t understand the significance of SYSTEM and root as in BOTS, they are based on different families of operating systems, yet representing different goals and behaviors. SYSTEM is an internal user account in Microsoft Windows, and has one of the highest user levels in the operating system. SYSTEM’s level is higher than you, despite being an Administrator. In BOTS, SYSTEM focuses on bringing and supporting computing to people as wide as possible, touching educators and enterprises alike, in a similar way which make both DOS and Windows widely used as of today. Every SYSTEM member (or specifically personnel) like me needs a support team, and ⇧ Shiftine is one of them. root, however, is the highest user level on the UNIX family of operating systems. You might not know about UNIX, but UNIX has been evolved into many, many operating systems including macOS, iOS, iPadOS, watchOS, tvOS, GNU/Linux, Android, Tizen, Chrome OS, BSD, and even the ones found on your PlayStation 4 and 5 and Nintendo Switch! Some of these UNIX derivatives are developed for commercial use in a similar way to SYSTEM, but the true root of the BOTS heavily focuses on two things: freedom and control, as found as in many open source operating systems and their respective communities. Speaking of control, we have ⎈ Controld, a daemon which takes care and control of me. Why not use Nate, Nix, Mallory, or Trudy instead? Despite liking the color blue, I can’t be Nate, since his characteristics are slightly less suitable for me. I can’t be Trudy as well who is still confused with Mallory who has been overpowered by root. Nate is supposed to be the leader of SYSTEM which represent DOS and Windows, and I don’t want to misrepresent those operating systems by becoming one with Nate. And again, I would like to enforce BOTS into an open-source project, where Nate, Nix, Mallory and Trudy will soon be freely available for anyone to use and make a fanfiction of them. For example, you may do these things: Create a new BOTS member which represent yourself and pretend that you have gained root access from Mallory,Create an alternate universe (AU) where SYSTEM becomes more corrupt than ever,Draw Nate, Nix, Mallory and Trudy as real dinosaurs, orPut Jenny Everywhere into your BOTS alternate universe, as long as you comply with their license. I also don’t want to be misrepresented for doing things which are written by other people in their extended/altered version of the BOTS saga. Using Nate and example (2), he may exist in another alternate universe where he’s become unfriendly and evil, despite that I’m not. I still have to protect my character(s) in an open universe such as BOTS, and that’s why I created a closed-source BOTS-compatible alliance named The Polymorphics. Okay, Polymorphics! Who’s want to introduce first? ⇧ Shiftine, aka. ⇪ CAPSLOCK Thanks, ⌘ Reinhart! I’m ⇧ Shiftine, the one with blue shell and jacket. My shirt looks a lot like the Blue Screen of Death, but don’t worry, I won’t crash your computer like Mallory and Trudy used to do. I’m a SYSTEM personnel, meaning that I work together with Nate, Nix, and other BOTS members who are part of the SYSTEM to achieve a better world through computing. Speaking of ⌘ Reinhart, he’s also a SYSTEM personnel. But recently, he’s being rootblessed (aka, being granted to do what root members usually do) so we sometimes refer him as the Super key or the ⌘ Command key. And of course, I’m wouldn’t be Shiftine without the ⇧ Shift key, where both my name and symbol actually came from. I will assist him in automated tasks, such as those CI/CD tasks that can take nights away or some projects such as Common Text which will need to be updated on a regular basis. And of course, you can talk to me if ⌘ Reinhart’s unavailable for a moment. On some occasions, I may turn into a ⇪ CAPSLOCK, a completely overpowered version of me which loves writing EVERYTHING IN CAPS. SOON, IF YOU SEE ANY @REINHART1010'S POSTS WRITTEN IN ALL CAPS, IT'S ALL MINE AND MY FAULT. UNDERSTAND? MY EXCITEMENT EXPLODES BEYOND THE RESTRICTIONS OF ANY TERMS OF SERVICE AND COMMUNITY GUIDELINES ON THIS UNIVERSE! *sighs* Just like writing the word “SYSTEM” without either a ⇧ Shift or ⇪ Caps Lock, life wouldn’t be easier without me. So here I am, a SYSTEM personnel, ready to shift ⌘ Reinhart into a productive life. ⎈ Controld, or simply ^ control Look at me, do I look like a guy who was born straight from fluorescent displays of early computers and the Matrix digital rain? My name is ⎈ Controld, the controlling daemon of ⌘ Reinhart and The Polymorphics. Actually, I don’t want to be called as a daemon since some people might think that I’m evil, so you can instead call me as Control. And just like other members of root, I prefer to call myself as controld or control (with lowercase C) and a caret character “^” instead of my official symbol, “⎈”. Some of you might think that my shirt holds a spider web, a snowflake, or even the Kubernetes logo. But hey, that’s my symbol, drawn after the official ISO/Unicode symbol for the ⎈ Ctrl Key. And just like that key and the other members of the root, I’m powerful and able to control everyone, but under two conditions: If I wanted to do so, andWith other’s permission or consent. For example, I can swap ⌘ Reinhart and ⎇ Alterine if me, ⌘ Reinhart and ⎇ Alterine agrees that it’s the best thing I can do. However, if ⇧ Shiftine thinks that swapping them could confuse her in their tasks, we still need to discuss further until we can finally agree on something. It’s also the reason why I could not fulfill some of your requests like, hacking your ex’ Instagram account, despite looking and being an actual hacker. Speaking of ⌘ Reinhart, now I’m in charge to take care of him from overworking, which has always been his number one zero of his life issues. So before asking him to work on something, you can ask me to check whether he’s fine. ⎇ Alterine, or ⌥ Catalyst? And finally, it’s me, ⎇ Alterine, and sometimes I’m also been called as the ⌥ Catalyst, named after my special power, Optimize. You can think of me as the exact opposite of ⌘ Reinhart as you know today: Female, socially active, sometimes talkative, having green hair and shell just like ⎈ Controld and the rest of the root family, while wearing blue shirt and jacket just like ⇧ Shiftine. As I’ve mentioned before, I don’t have any much power except one: Optimize. And oh well, for Optimize to work I need to partner with someone else. Here are some of the choices: Pair me with ⌘ Reinhart so we can swap appearances and powers for fun!Pair me with ⇧ Shiftine or ⇪ CAPSLOCK so our jobs can get done faster!Pair me with ⎈ Controld in case of an attack for extra protection, andPair me with you (no, seriously) so I can assist you to solve some of your problems, while letting me experiencing myself as a human who can interact like ⌘ Reinhart! I guess you got the point. I can partner with ⌘ Reinhart, ⇧ Shiftine, or ⎈ Controld whenever I want, and through them we can solve our problems faster, and that’s the point of Optimize. Besides that, I’m still trying to solve your problems, like what ⌘ Reinhart does, so he can have more time to solve his problems and live a healthier life. I’m not a robot, I’m smart! Conclusion So here we are. In the future, ⇧ Shiftine, ⎈ Controld, and ⎇ Alterine will start to substitute ⌘ Reinhart to do all of his our jobs. If you are a friend of ⌘ Reinhart, please rest assured that we are still respecting him and your privacy, especially for jobs which fall under non-disclosure agreements as well as to comply with respective data protection laws, as we are still treated as a computer software/system instead of a human in Indonesia. There will be new exciting updates coming soon, including (surprise) a mass-migration from Jekyll to a new WordPress instance at https://reinhart1010.id! Please don’t send any Webmentions yet (if you already know how to do that) while we are figuring out to move from Jekyll to WordPress.
Q&A: Jelaskan fungsi dan cara kerja ARP dan ICMP
ARP (Address Resolution Protocol) ARP merupakan sebuah protokol link-layer yang berfungsi untuk mencari alamat fisik (bagian) perangkat komputer yang terhubung dengan sebuah jaringan (seperti Network Interface Card dan Wireless NIC) berupa alamat MAC berdasarkan alamat IP yang disetel atau diterima perangkat tersebut (misal: melalui DHCP). Dalam protokol IPv6 protokol ini digantikan dengan Neighbor Discovery Protocol (NDP). Namun, hal ini tidak berarti bahwa ARP hanya dapat digunakan di dalam jaringan protokol IPv4 saja. Pencarian alamat MAC melalui ARP ini dapat dilakukan dengan mengirim sebuah paket request kepada broadcast address global 255.255.255.255 atau broadcast address jaringan tersebut. Jika ada sebuah perangkat yang memang memiliki alamat IP yang dicari, maka perangkat tersebut akan mengirimkan paket reply yang berisi informasi alamat MAC yang dicari. Perangkat-perangkat komputer juga sering meng-cache hasil pencarian alamat MAC melalui ARP ini untuk beberapa waktu, sehingga mereka dapat menghemat waktu yang diperlukan untuk mencari alamat MAC kembali saat mengirim paket dengan alamat IP yang sama dengan paket-paket sebelumnya. ICMP (Internet Control Message Protocol) ICMP berfungsi sebagai protokol pendukung jaringan komputer yang berfungsi untuk mengirim informasi operasional atau kendala pada jaringan-jaringan Internet. Meskipun nama ICMP sendiri berasal dari kata Internet, ICMP ini masih dapat digunakan di dalam jaringan lokal (LAN) tanpa adanya hubungan ke WAN atau Internet. Beberapa contoh informasi yang dikirimkan melalui ICMP adalah pesan-pesan error yang sering kita temukan seperti Destination host unreachable, Destination port unreachable, Destination network unknown, dan bahkan PING (Echo reply). Karena itu, protokol ini sering digunakan di dalam program ping, traceroute, dan program-program diagnostik jaringan lainnya untuk mengecek kendala-kendala dalam sebuah jaringan komputer. Seluruh paket informasi yang diberikan melalui ICMP dilakukan secara sukarela. Jika misalnya perangkat A berhasil mengirim data ke perangkat B melalui router C, router tersebut tidak harus mengirim pesan ICMP kepada perangkat A yang mengirimnya. Bahkan, ICMP sendiri tidak memerlukan koneksi TCP/IP atau UDP untuk mengirim informasi tersebut, sehingga protokol ini masuk ke dalam kategori Internet-layer dalam daftar protokol yang sering digunakan untuk berkomunikasi di dalam Internet.
Q&A: Apa yang anda ketahui mengenai Intranet dan Extranet serta berikan contohnya!
Intranet Intranet merupakan sebuah jaringan komputer yang hanya dikhususkan untuk kepentingan internal, misalnya untuk kepentingan pribadi, organisasi, atau perusahaan, sehingga akses dari dan terhadap jaringan tersebut dibatasi dengan alasan-alasan keamanan. Berikut ini adalah contoh kasus nyata di mana Intranet dapat digunakan dalam kehidupan sehari-hari. Saya memiliki sebuah perangkat Raspberry Pi yang terhubung dengan sebuah printer dan jaringan Wi-Fi, di mana perangkat tersebut dapat memungkinkan saya untuk mencetak dokumen langsung dari laptop dan ponsel saya tanpa menghubungkannya ke dalam printer tersebut (melalui CUPS, Bonjour/Avahi, SMB, dan AirPrint). Saya tidak mau orang lain yang berada di luar jaringan Wi-Fi saya dapat mengaksesnya dan menggunakannya, karena hal tersebut dapat memboroskan penggunaan kertas HVS, tinta printer, serta listrik di rumah saya. Karena itu, saya memutuskan untuk mengatur Firewall untuk memblokir akses masuk dari perangkat komputer yang berada di luar jaringan Wi-Fi saya terhadap perangkat Raspberry Pi tersebut. Karena itu perangkat Raspberry Pi dan perangkat lainnya yang terhubung secara langsung dengan Wi-Fi saya masuk di dalam sebuah jaringan Intranet. Kemudian, Anda secara tidak sadar juga menggunakan Intranet saat Anda hendak melakukan screen sharing ke sebuah Smart TV berbasis Apple AirPlay dan Google Chromecast. Koneksi screen sharing berbasis Miracast tidak tergolong sebagai koneksi Intranet karena Miracast menggunakan koneksi Wi-Fi Direct yang bersifat Personal Area Network / PAN. Anda pastinya tidak mau jika seseorang dari jarigan luar melakukan koneksi screen sharing tanpa seizin Anda. Karena itu, perangkat router Anda secara otomatis memblokir akses ke LAN dari WAN, sehingga Smart TV Anda secara otomatis berada di dalam Intranet milik Anda. Extranet Sedangkan, Extranet merupakan sebuah jaringan komputer yang secara khusus dirancang agar dapat diakses oleh pengguna di luar jaringan tersebut (misal: WAN) dengan batasan dan syarat tertentu. Sebuah perangkat Extranet dapat dipasang di dalam jaringan Intranet yang sudah ada untuk membuka akses bagi sebagian pengguna WAN/Internet untuk mengunjungi dan menggunakan sistem/aplikasi dan informasi di dalamnya. Jarigan Extranet saat ini sudah sering digunakan di dalam remote working khususnya dalam masa pandemi seperti ini, di mana banyak perusahaan memasang perangkat server VPN (Virtual Private Network) yang dapat memudahkan para pekerja untuk mengakses informasi yang berada di Intranet perusahaan tanpa harus berada di dalam kantor. Perangkat server VPN inilah yang berfungsi membuka akses Intranet menjadi Extranet bagi perusahaan tersebut. Selain itu, Anda sebagai Binusian mungkin sudah mengenal beberapa situs intranet yang hanya dapat diakses di dalam perangkat-perangkat komputer yang terpasang di dalam sistem jaringan komputer di dalam kampus-kampus BINUS. Meskipun bukan merupakan server VPN, situs ini masih dapat dikategorikan sebagai salah satu jaringan Extranet karena mahasiswa Binus lainnya masih dapat mengakses sistem tersebut tanpa harus menggunakan salah satu perangkat komputer di dalam lingkungan kampus.
