Services
This server provides the following services to the public.
AUR repository
See https://build.kilabit.info for more information.
DNS server
The DNS server is run using rescached on the following port,
-
DNS over UDP at port 53,
-
DNS over HTTPS at "https://kilabit.info/dns-query",
-
DNS over TLS at port 443.
Check the IP address using dig or ping to domain kilabit.info.
Some stranger abuse the UDP port 53, so the service may be get blocked
at some point.
We use CloudFlare DNS as parent name servers.
Projects
asciidoctor-go
The asciidoctor-go is the Go module to parse the AsciiDoc markup and convert it into HTML5.
awwan
awwan is configuration management software, infrastructure as file and
directory layout.
In other words, awwan is command-line interface to execute multiple lines
of command in the local or remote server using SSH.
Do you have a collection of shell scripts to manage one more similar server? Do you ever want to execute only part of your shell script in remote server? Are you get tired with learning others syntax and tools for provisioning your own server, while you need is a handful knowledge of shell script?
If yes, awwan is the right tools for you.
ciigo
ciigo is a program to write static web server with embedded files
using asciidoc markup language.
This site and golang-id.org is written with ciigo as framework.
golang-id.org
This website is my second contribution to Go community. Its goal is not only to provide help, through translation, for Indonesian to learn more about Go but also to provide an ecosystem for Indonesian Go community, for example, vlog and blog in Indonesian language, and sharing open source works written in Go. The website is freshly launched, they are still more works to be done, though.
gorankusu
gorankusu is a Go module that provide HTTP service with web user interface
for testing HTTP endpoints (like Postman) and for load testing.
For the load testing we use
vegeta
as the backend.
haminer
haminer is a library and program to parse and forward HAProxy logs to InfluxDB for mining HTTP requests.
hunspell-id

jarink
Jarink is a program to help web administrator and developers to inspect and maintains their website. Currently, it has the feature to scan and report for broken links.

pakakeh.go
pakakeh.go is collection of Go packages.
The most outstanding packages are WebSocket (server and client), DNS (server
and client), email (client only), STMP, and MemFS (memory file system).
rescached
Rescached is resolver cache daemon. It is a DNS forwarding server, serve the clients queries, but also caching all the queries and answers for later use. The idea is to minimize network traffic for outside DNS queries and to manage local zone files. The first implementation was written in C++ and then re-written using Go.
tour.golang-id.org
The tour.golang-id.org is translation of their original website https://go.dev/tour to Indonesian language, to help newcomers learning the Go programming language. This is my first contribution to Go community.
Projects: archived
The following projects is not maintained anymore.
beku
(Deprecated in favour of Go module)
Beku is command line program to manage Go packages in user’s environment
(GOPATH or vendor directory).
Beku provide syntax like pacman.
This program exists long before before godep or Go module exist and
stable.
duitku
Duitku is the Go module for duitku.com.
The project is started because in my previous company we use duitku.com for payments and there is no open source Go module for it, so I create it.
kamusku
kamusku is open source project that provides HTTP API for Kamus Besar Bahasa Indonesia. The idea of this project is to provide command line interface to lookup the definition of Indonesia words from terminal and from Telegram bot.
This project is discontinued due to copyright issues, where the KBBI administrator send direct email warning to me after announcing this project on public Telegram channel. The email said that my program store data gathered from KBBI server.
The source code and implementation does not store the KBBI data into storage, only caching it in the memory to minimize identical requests to KBBI server.
This project depends on the kbbi module (see below), as the base layer for scrapping the definition.

kbbi
kbbi is the Go module and client program to lookup definition of Bahasa Indonesia words from the Kamus Besar Bahasa Indonesia.
libvos
libvos is a C++ library. First implementation was intended for reading and writing Delimited Separated Value (DSV) data, but then its evolved and have more capabilities. Current features included Buffer module, File module, Socket module, reading and writing INI file format, FTP (server and client) module, DNS module, and Oracle Client Interface module.
This library is the building block for the vos project (see below).
vos
Vos is a program to process formatted data, i.e. CSV data. Vos is designed to process a large input file, a file where their size is larger than the size of memory, and can be tuned to adapt with machine environment. Vos can do sorting, formatting, filtering, and join, by reading input file and its configuration script. Its written in C.
This project is inspired by IRI CoSort®, a fast, affordable, and easy-to-use sort/merge/report utility, and a full-featured data transformation package. I know CoSort when working at one of telco in Indonesia.
For the completion of my bachelor degree, I wrote a paper which research
the best sorting algorithm for big data on low memory system.
vos is the proof of concept of that thesis paper.
