Hello, World!

We are Hackers and Jackets, or hackjacks for short. Well, of course, you can find everything about Reinhart and much of his projects here.

We talk about many different things here in different language: from the human-speakable English and Bahasa Indonesia to languages which those developers, hackers, and even robots like to speak: programming languages. That's why many people and robots were overwhelmed with all the clutter on this site's "Blogs" page, and that's why we're here to help.

TL;DR: Read all posts written in English by clicking here. Well, if you're still reading until now, our blog site is divided into multiple categories:

Everything about Reinhart and his our projects

If you just want to know all of Reinhart's latest updates, just look for his:

  • Updates
  • Opinions

or click one of the links below to see official announcements for his our projects:

  • Jackpot GBK
  • Kuyliner / Food Navigator

You can also check out Shiftine's logs to see everything she's done to keep these projects working.

Resources for BINUS University students

Now that if you're a student or alumni of BINUS University, you might found out these things useful:

  • Everything tagged under BINUS
  • BINUS posts which are specific to School of Computer Science (SOCS). Note that Reinhart is currently a manager of HIMTI BINUS University.
  • BINUS posts which are specific to Visual Communication Design, also known as DKV. DKV? Oi!

More about us

Now if you're interested in everything about technology, this is where we, Hackers and Jackets, are into. We're divided into two master main groups based on our visions in tech: SYSTEM and root.

We wrote together How Does IT Work, a blog post series dedicated to explaining technology behind the scenes, including how cybersecurity attacks and scams work. And sometimes we hold a new JASS (Just Another Session with Us), which is just a symlink to AMA (Ask Me Anything).

And of course, #WeAreAllScambaiters so, you can find our investigations here.

The SYSTEM's Knowledge Base

If you're a normal user, studying, and/or working with IT as a profession then check out The Knowledge Base, a set of guides curated by SYSTEM hackjacks to help you get things done. You will find resources, tips, and tutorials about:

  • Using programs, apps, and websites
  • Using software libraries and frameworks
  • Algorithm and programming
  • Using the Command Line Interface (CLI)

Tales from the rootverse

Meanwhile, if you're up for an adventure, jump together with us into the rootverse for all things tech, especially when it comes to cybersecurity and digital rights. And breaking the "antisocial" stigma of developers out there.

Please note that you might found a lot of technobabbles in the rootverse for two reasons: to be compatible with robots who have limited powers of language processing, and that what makes the rootverse, root. The folks at SYSTEM and root are working together to build a new dictionary for humans to understand what is really going on.

Support Us

Now, congratulations! You have read the entire text on this homepage. If you're an Indonesian citizen, you can support our hard work through Saweria which accepts payments from your favorite mobile banking and e-wallet apps (through QRIS). Merch are coming soon, so stay tuned!
