I am talking about a broader genre, whether it is about career and business, health and wellness, relationships, or communication. They fall into the same category that this post talks about: books that give advice directly to the reader. They are full of fillers and repetitive ideas Self-help books are trying to bring a few main ideas to readers. If we summarize them, it may be sufficient to represent them in a few bullet points in 2-3 pages.https://aguno.xyz/post/2026/06/01/when-ai-makes-ordinary-life-feel-good/Mon, 01 Jun 2026 00:00:00 +0000https://aguno.xyz/post/2026/06/01/when-ai-makes-ordinary-life-feel-good/I have never been able to focus on work with AI. Whenever I work with an AI agent, I always tend to multitask. Maybe this is part of the lowest spectrum of ADHD, a part of myself that I can’t avoid. It is not a pleasant feeling or experience to work with multiple agents. You can name a few best practices about how to work with AI. To some degree, they work.https://aguno.xyz/post/2026/02/22/blankon-revival-project-part-1/Sun, 22 Feb 2026 00:00:00 +0000https://aguno.xyz/post/2026/02/22/blankon-revival-project-part-1/These are my personal notes on the BlankOn Revival Project. Although many of the ideas discussed here have been seriously considered by the BlankOn Foundation team, they do not necessarily represent the official views of the organization. Many of these reflections emerged from discussions with several individuals, not all of whom are mentioned here. I would like to sincerely thank them for their insights and contributions. Step Down, Twice There are many reasons behind this, but I do not intend to discuss them all one by one.https://aguno.xyz/post/2025/11/22/idsw-2025-lightning-talk-why-local-tech-communities-are-important-and-how-to-run-them/Sat, 22 Nov 2025 00:00:00 +0000https://aguno.xyz/post/2025/11/22/idsw-2025-lightning-talk-why-local-tech-communities-are-important-and-how-to-run-them/A 5-minute lightning talk session is surprisingly difficult for me, so this blog post serves as a backup in case I can’t properly deliver what I want to say. Thank you for reading! Teman-teman, nama saya Piko. Saya lahir dan tumbuh di pulau Lombok, sebelahnya Bali. Latar Belakang Tahun 2015, saya pindah ke Jabodetabek. Setelah 1 tahun di sini, perasaan saya campur aduk. Di satu sisi saya senang banget karena di sini banyak sekali event-event tech yang bisa saya ikuti dan membantu saya bertumbuh kembang sebagai software engineer secara profesional dan memberikan saya bermacam-macam opportunity.https://aguno.xyz/post/2025/07/11/feedback/Fri, 11 Jul 2025 00:00:00 +0000https://aguno.xyz/post/2025/07/11/feedback/I think the luckiest people are those who have people that care about them and know how to accept and appreciate that care properly. One of the shapes of caring is feedback, which sometimes is hard to swallow. Thus, delivering one requires specific skills just as important as receiving one. When someone has concern about their friend, coworker, or even their favorite barista’s latte art skills, that concern often comes from a place of wanting them to do better, not from wanting to tear them down.https://aguno.xyz/post/2025/01/05/community/Sun, 05 Jan 2025 00:00:00 +0000https://aguno.xyz/post/2025/01/05/community/Communities allow me to see the world in different perspectives. They are like bubbles, but each contains portions of other kinds of bubbles. People from different backgrounds come and go, bringing diverse goals, intentions, opinions, and politics. Yet, we gather for the same domain or shared interest. I grew up in communities. They filled the gaps left by my parents (who are still alive but were largely absent in their roles).https://aguno.xyz/now/Wed, 01 Jan 2025 00:00:00 +0000https://aguno.xyz/now/This is a now page.

They allow us to identify performance issues in real-time, improve application performance, troubleshoot problems, plan capacity, and identify security vulnerabilities. The performance tracing implementation is done by: Running an agent beside your service(s). One agent could be used by several services. The agent acts as gateway to send data to Datadog APIs.https://aguno.xyz/post/2023/03/06/how-i-created-a-pull-request-on-my-first-day-at-work/Mon, 06 Mar 2023 00:00:00 +0000https://aguno.xyz/post/2023/03/06/how-i-created-a-pull-request-on-my-first-day-at-work/I’m not talking about myself regarding the pull request (okay, I’ll talk about it a bit at the end of this blog post), there is nothing special about it.

Mari saya mulai dengan Firefox. Harus bisa apa? Codebase Mozilla terdiri dari berbagai macam bahasa pemrograman, mulai dari C, C++, Java, JavaScript, HTML/CSS, Swift, Python dan lainnya.

It’s handmade, looks cheap, err yeah, literally cheap. It advertised as long-lasting with durable stitching. I didn’t immediately write a review and want to use the wallet first for months before writing about it. My previous wallet is an ordinary foldable wallet and I was not happy with that. My entire stuff in the previous wallet: What comes to my mind when purchasing the minimalist wallet was I’ve to get rid of some of the stuff.https://aguno.xyz/post/2019/04/05/rewriting-the-irgsh/Fri, 05 Apr 2019 00:00:00 +0700https://aguno.xyz/post/2019/04/05/rewriting-the-irgsh/The reasons behind my decision to rewrite IRGSH are ranged from personal motivation to BlankOn project direction. After Uluwatu released, a hard disk died in one of BlankOn development server. Unfortunately, the machine is the important one. The hard disk contains IRGSH, the backbone of BlankOn Linux development. The fortunate side is this happened after Uluwatu released. A year before this incident, Estu and I have tried to put IRGSH into production from scratch and it is really hard to do so.https://aguno.xyz/post/2019/03/17/ffmpeg-scene-detection/Sun, 17 Mar 2019 00:00:00 +0700https://aguno.xyz/post/2019/03/17/ffmpeg-scene-detection/In the beginning of 2019, I rent a comfortable room near my office so I could just do a walk to reach the office and meet my coworkers.

A locksmith introduced me to the basic understanding of how most locks work and how to break them. So, I tried it again with a transparent training padlock. It seems easy but on real locks, it really hard and needs patience as you can’t see the pin tumbler. Instead of using lock picking toolset, bending your own paper clip is more challenging.

I often requestioned myself whether I still need to be a minimalist or not. In the middle of 2018, I got these books that help me to answer the question.

We named it, “idaman polos” principle. We love anything that simple, plain and minimalist. Even we debated about how plain should be the colour of our saroong. But, we grew up in no minimalist style. Our shared room are not minimalist at all. We’ve bunch of junks as our hobbies need them.

He has done so much things in his young age, bringing real changes to the world. The news about his suicide really strucks me back then. In 2014, Brian Knappenberg released a documentary about Aaron, titled The Internet’s Own Boy. It gives me more broad views about Aaron’s activities.

Bagi saya, buku yang saya peroleh dari kantor Yayasan Air Putih itu sangatlah emosional. Buku itu menceritakan tentang rumitnya distribusi bantuan logistik dan pengambilan keputusan di antara berbagai kepentingan dari pihak-pihak yang datang untuk membantu Aceh.

Unlike Kineruku (will write about this soon), only about 1/3 of the books are fiction, but they are carefully curated and, as I said before, some of them are rare items.

I don’t have many friends and I even don’t know the real definition of friend that I should use. That is why I stuck with old friends, but old friends are easy to lost bond with and I also don’t know where the real bond lies.https://aguno.xyz/post/2018/01/16/my-slackware-post-install-guide-for-thinkpad-x200/x220-laptop/Tue, 16 Jan 2018 00:01:00 +0000https://aguno.xyz/post/2018/01/16/my-slackware-post-install-guide-for-thinkpad-x200/x220-laptop/There are times where I flushed the Slackware partition for another purpose.

Kesalahpahaman ini sudah sering saya temui, terutama saat berusaha menjelaskan apa itu sertifikat elektronik dan tanda tangan digital. Beban pemerintah untuk memasyarakatkan teknologi ini sepertinya memang berat. Dalam sudut pandang awam, berkas PDF yang berisi sebuah sertifikasi / pengakuan dapat disebut sebagai sertifikat digital, karena benda itu adalah ‘sertifikat’ dan bentuknya digital.https://aguno.xyz/post/2017/09/09/about-the-coffee/Sat, 09 Sep 2017 00:03:00 +0000https://aguno.xyz/post/2017/09/09/about-the-coffee/Some people talked about how bad I am at coffee.

Memang mereka tidak sekolah, tidak berpakaian bagus, tidak punya tempat tinggal yang layak, tapi mereka hidup.https://aguno.xyz/post/2017/07/05/vortex-core/Wed, 05 Jul 2017 00:01:00 +0000https://aguno.xyz/post/2017/07/05/vortex-core/Saya sudah lama sekali mengidam-idamkan papan tik mekanik. Kebetulan bulan lalu saya berulang tahun dan saya jadikan alasan untuk menghadiahi diri sendiri. Akhirnya terpilihlah dua benda : jam tangan Casio F91W yang mungil dan papan tik mekanik Vortex Core. Apa perbedaan papan tik biasa dengan papan tik mekanik? Papan tik biasa yang banyak digunakan sekarang ini disusun oleh beberapa lembar membran dan setiap tombolnya terdapat karet berbentuk kubah (dome). Model seperti ini tidak tahan lama karena karet bisa rusak oleh kelembapan yang kurang tepat.https://aguno.xyz/post/2017/05/07/rekontruksi-irgsh-2/Sun, 07 May 2017 00:01:00 +0000https://aguno.xyz/post/2017/05/07/rekontruksi-irgsh-2/DRAFT Tulisan kali ini mengupas tentang irgsh-web, salah satu dari 3 komponen utama IRGSH. Sebelum menuju kesana, mari kita petakan alur kerja pengembangan distribusi BlankOn secara keseluruhan. (1) Infra menyiapkan repropro dan layanan repository. Reprepro sudah di-update ke Sid. (2) Pemaket memasukkan paket ke IRGSH. (3) Paket dibangun oleh IRGSH. (4) Paket jadi dikirim ke ke irgsh-web/taskinit (5) Paket jadi dikirim ke irgsh-repo. (6) Paket jadi disuntik ke reprepro oleh irgsh-repo.https://aguno.xyz/post/2017/04/24/rekontruksi-irgsh-1/Mon, 24 Apr 2017 00:01:00 +0000https://aguno.xyz/post/2017/04/24/rekontruksi-irgsh-1/Sebelum memulai tulisan berseri ini, saya ingin mengucapkan terima kasih ke para pengembang BlankOn, terutama senior dan pensiunan, pak Aftian dan pak MHY. Tanpa mereka, kami tidak tahu IRGSH mau diapakan lagi. Terima kasih! Terima kasih juga untuk teman-teman pengembang generasi baru, terutama tim Infra, tim Pemaket dan tim Riset. Kisah dimulai setelah Tambora rilis, dimana beberapa pengembang kunci memilih pensiun. Keputusan ini sangat penting karena terkait erat dengan regenerasi. Dan apa yang ditinggalkan untuk generasi penerus sangat menarik.https://aguno.xyz/post/2017/04/17/salah-satu-pendakian-terbaik/Mon, 17 Apr 2017 00:01:00 +0000https://aguno.xyz/post/2017/04/17/salah-satu-pendakian-terbaik/Ini adalah pendakian ulang dari pendakian tahun lalu.

Kali ini kami mencapai puncak. :)https://aguno.xyz/post/2017/04/05/blankoding-uluwatu-di-surabaya/Wed, 05 Apr 2017 00:01:00 +0000https://aguno.xyz/post/2017/04/05/blankoding-uluwatu-di-surabaya/Apa itu BlanKoding? Baca hackathon. Awal April kemarin, BlanKoding diinisiasi oleh Menejer Rilis di Surabaya, tepatnya di kantor Radnet. Yang hadir antara lain Pak Menejer, Pak Aftian, Pak Ben, Pak Darian dan saya sendiri. Tak lupa pula kami mengunjungi Duduk Sampean, menemui salah satu pengembang BlankOn yang belum pernah saya temui tatap muka, Pak Azis Ws. BlanKoding ini ngapain aja? Kami mempelajari dan merekontruksi IRGSH, merapikan infra, menerapkan disiplin devops ke proyek BlankOn dan yang terakhir, makan sego boran!https://aguno.xyz/post/2017/03/26/menyelamatkan-aku/Sun, 26 Mar 2017 00:01:00 +0000https://aguno.xyz/post/2017/03/26/menyelamatkan-aku/Alkisah (tapi ini nyata lho), harddisk rani nyaris tewas dan badsector-nya sudah lumayan. Kondisi ini berimbas ke beberapa layanan BlankOn, salah satu dan yang terpenting adalah Aku, bukan kamuuu. Aku adalah layanan single sign on (SSO) untuk layanan-layanan BlankOn yang lain. Contohnya, dengan satu akun, kita bisa masuk ke panduan.boi maupun dev.boi. Sumber kode Aku dapat dikunjungi di sini. Saweran harddisk dibuka, Tim Infrastruktur bergegas mengamankan data-data, Menejer Rilis berkelana ke timur membawa harddisk baru untuk rani.https://aguno.xyz/post/2017/03/24/mencari-ning/Fri, 24 Mar 2017 00:01:00 +0000https://aguno.xyz/post/2017/03/24/mencari-ning/Ditulis berdasarkan kisah nyata dari seorang kawan. “Gol gol gol, ale ale ale”, Kamu ingat potongan lagu itu. Sepak bola dan 1998. Kamu jadi ingin tertawa mengingat-ingat betapa banyak energi yang kamu miliki saat masih kecil dulu. Kamu bisa berlari kesana kemari, menendang bola, menyikut temanmu, berteriak lepas. Sampai sore. Sampai petang. Namun sebelum semua itu, kamu menggeser lembar ingatan beberapa tahun ke belakang.

Minggu lalu saya ada keperluan mendesak dan harus pulang ke Lombok (sekarang berdomisili di Depok). Kepulangan sebelumnya tidak begitu nyaman dikarenakan (nyaris) menghilangnya angkutan umum (disebut Bemo) di Mataram dan mesti menyewa taksi untuk kesana-kemari. Oleh sebab itu, saya ingin membawa sepeda lipat. Dari penelusuran di internet, saya mendapat beragam informasi terkait cara membawa sepeda ke pesawat.https://aguno.xyz/post/2017/01/30/recovering-mongodb-database-from-oplog/Mon, 30 Jan 2017 00:01:00 +0000https://aguno.xyz/post/2017/01/30/recovering-mongodb-database-from-oplog/Shit happens occasionally. Last week, a MongoDB replication pair (master-slave) on production losts its databases. According to the investigation result, it caused by power failure that happened too often which lead to storage corruption. If the power failure happens while the replication set still syncing the oplog (operation logs), the database will be corrupted and MongoDB will drop it, without confirmation. The last backup managed at May 2015. Quite scary.https://aguno.xyz/post/2017/01/19/baduy-in-the-wild/Thu, 19 Jan 2017 00:01:00 +0000https://aguno.xyz/post/2017/01/19/baduy-in-the-wild/In the wild, karena ia seorang diri di salah satu kota sibuk di Indonesia. Kota bising ini pastilah tempat antah berantah buatnya. Ini adalah kisah beberapa minggu yang lalu, ketika saya berjumpa dengan seorang suku Baduy di pinggir jalan Margonda Depok pada siang bolong.

Saya tertarik terutama karena trailernya memperlihatkan aksi tim yang direncanakan dengan rapi dan ada scene meretas komputer. Jadi penasaran, mereka ngapain aja. Namun ternyata tidak sesuai ekspektasi. Saya tidak akan mengulas tentang kualitas film dan plotnya, hanya sisi teknis mengenai “dongle”.

Parallel coding was fun! The problem that I’m trying to solve is a BFS pathfinding algorithm. I want to make the solution done in bi-directional finding with the help of parallel computing. I’ve wrote the code some years ago in Javascript and now need it run in Python with mpi4py. Since I’m too lazy to port the code, I seek for an automate solution and found this js2py library.https://aguno.xyz/post/2016/11/22/watching-before-the-flood/Tue, 22 Nov 2016 20:00:00 +0000https://aguno.xyz/post/2016/11/22/watching-before-the-flood/Several months ago, I read some news about Leonardo DiCaprio visited Indonesia. Meet up with elephants, orangutan, and so on. For what purpose? Now, I know why he came. Before The Flood is a documentary by National Geographic about climate change, starring Leonardo DiCaprio. I think it’s very important issue so I create a poster for the screening event and invite other students at campus. The documentary is publicy available in Youtube.https://aguno.xyz/post/2016/11/20/reading-books-on-the-commuter/Sun, 20 Nov 2016 23:00:00 +0000https://aguno.xyz/post/2016/11/20/reading-books-on-the-commuter/So, I’ve thrown this question on social media : what if you pick a good book, read it from morning till night in the commuter? you just stop by for eat and pray. from bogor to elsewhere then back to bogor.

Beberapa bulan sebelumnya saya membeli Thinkpad X220 dan sekarang dapat ini, benar-benar menimbulkan kegalauan tak terkendali. Tapi akhirnya saya bisa membandingkan, Thinkpad klasik dengan Thinkpad modern yang berusaha ditonjolkan Lenovo sekarang ini. Seperti biasa, begitu menyentuh benda baru, saya tidak langsung menulis ulasannya. Saya perlu menggunakannya selama beberapa waktu sampai benda tersebut menunjukkan kekurangannya.https://aguno.xyz/post/2016/11/10/vue/Thu, 10 Nov 2016 12:00:00 +0000https://aguno.xyz/post/2016/11/10/vue/The first time I heard about Vue was last year and didn’t pay enough attention. People talks this and that, and I stay happy with Angular. Now I’m tired of Angular, haven’t choose yet between Angular2 or React for the future use. So (for educational purpose) I’m making a complete telegram clone app using socket.io and take a try with Vue. It is so simple. Really, I was surprised by the simplicity of Vue.https://aguno.xyz/post/2016/11/10/letsgonesia-at-1000sd/Thu, 10 Nov 2016 11:00:00 +0000https://aguno.xyz/post/2016/11/10/letsgonesia-at-1000sd/We didn’t pass to the bootcamp.

Mereka mesin yang tangguh dan manis. Saya pertama kali melihat dan menyentuh X220 saat @winardiaris membawanya. Darah saya berdesir… Beli Yang membedakan komputer ini dengan Thinkpad X220 lain adalah baterai 9 cell dan SSD 128GB. Saya mendapatkannya (2 bulan sebelum tulisan ini terbit) dengan harga Rp. 4.000.0000. Tidak murah, tetapi saya tetap mengambilnya karena sudah berkesempatan memegangnya beberapa kali, memastikan semua komponennya bekerja dengan baik tak kurang suatu apa.https://aguno.xyz/post/2016/08/05/untukmu-untuk-kita-semua/Fri, 05 Aug 2016 12:00:00 +0000https://aguno.xyz/post/2016/08/05/untukmu-untuk-kita-semua/Seiring waktu berjalan, saya belajar tentang banyak hal. Hanya saja saya belum berkarya sebanyak apa yang saya pelajari. Saya melakukan hal-hal yang saya senangi, menggarap proyek-proyek kecil dan menantang, mengekplorasi tren baru, namun setelah nyaris jadi, semuanya tidak terlalu berguna. Iterasi ini sempat mencapai titik jenuh, membuat saya nyaris bosan mengetik kode dan memaksa mencari-cari masalah secara sengaja. Saya memulainya dengan prototype kasar dan setengah tidak yakin. Mengapa? Karena saya pesimis dan beranggapan bahwa yang menganggap masalah ini adalah sebuah “masalah” hanyalah saya sendiri, atau saya tidak menemukan orang lain yang sepikiran.https://aguno.xyz/post/2016/07/29/catatan-blankon-installer-3/Fri, 29 Jul 2016 12:00:00 +0000https://aguno.xyz/post/2016/07/29/catatan-blankon-installer-3/This is last paragraph from previous post : My current work still having double passphrase checking (which is annoying) on the boot process : on the GRUB and initramfs. It didn’t happens on the previous year and I have no clue yet (sitl regret about missing documentation).

KodeKreatif team and I was creating BlankOn remaster that included customized BlankOn Installer that support LUKS encryption over LVM. The most interesting and hard part was injecting bluetooth support to initramfs. The goal was the user would be able to decrypt their computer using a smartwatch, upon the initramfs.

Seperti catatan perjalanan sebelumnya, untuk mencegah hype yang tidak perlu, saya tidak akan menyebut destinasi perjalanannya. Hint-nya, gunung ini adalah salah satu dari sekian banyak gunung di Jawa Barat, dinamai dengan prefix ‘Ci-’, memiliki tinggi sekitar 2600 - 3000 MDPL. Kali ini saya juga tidak membawa barang elektronik. Tidak kamera, tidak ponsel.

Ingatan-ingatan yang paling rabun ini membawa kamu kepada sebuah sosok yang sudah kamu lupakan tapi kamu berusaha atau berpura-pura tidak lupa.

Awal-awalnya dulu saya selalu berusaha untuk mendapatkan tempat duduk. Namun lama-kelamaan, saya memilih untuk berdiri. Begini : Jika ramai hanya ada 2 slot tempat duduk yang kosong, jangan duduk. Jika tidak ramai, hanya ada 2 slot, dan hanya saya saja yang berdiri di sekitar slot tersebut, silakan duduk.https://aguno.xyz/post/2015/12/24/wakijo-dan-bapak-polisi/Thu, 24 Dec 2015 12:00:00 +0000https://aguno.xyz/post/2015/12/24/wakijo-dan-bapak-polisi/Saya berusaha merekontruksi kejadian ini tanpa menambah atau menguranginya.

Saya hanya pernah mendaki gunung Rinjani dan Tambora, jadi sudut pandang saya diambil dari pengalaman saya yang sedikit ini.https://aguno.xyz/post/2015/07/21/tai/Tue, 21 Jul 2015 12:00:00 +0000https://aguno.xyz/post/2015/07/21/tai/Karena suatu hal dan hal lain, saya tidak menyebutkan nama tempat yang saya kunjungi kali ini. Biarlah tidak usah jadi mainstream. Biarlah tempat ini menjadi tidak ramai. Jika kamu merasa tahu tentang tempat ini, ya silakan menebak-nebak sendiri. Tempat ini dikelola oleh Sembalun Development Community Center. Selain membayar restribusi, kami diberi kantong plastik untuk sampah dan beberapa peringatan lisan, tidak boleh ini dan itu. Sepertinya dikelola dengan baik. Terima kasih!https://aguno.xyz/post/2015/06/07/buku-buku-tua/Sun, 07 Jun 2015 12:00:00 +0000https://aguno.xyz/post/2015/06/07/buku-buku-tua/Sejak pindah ke ibu kota, saya beberapa kali menyempatkan diri untuk membeli buku bekas di Pasar Senen. Butuh sekitar 3 jam dari Bogor untuk tiba di sana. Sampai saat ini, saya baru mengunjungi tiga tempat penjualan buku bekas. Di dekat stasiun Pondok Cina, Pasar Senen, dan Pasar Senen Impres. Buku-buku yang paling menarik rasanya ada di Pasar Senen Impres, sekaligus buku-buku yang paling mengenaskan kondisinya. Di beberapa lapak di sana, buku-buku tersebut ditumpuk di atas alas kayu, kemudian ditutupi terpal seadanya.https://aguno.xyz/post/2015/05/15/catatan-mengenai-qemu-kvm/Fri, 15 May 2015 12:00:00 +0000https://aguno.xyz/post/2015/05/15/catatan-mengenai-qemu-kvm/Siapkan Pasang libvirt dan qemu. sudo apt-get install libvirt qemu Buat berkas harddisk qemu-img create hda.img 10G # buat hdd virtual ukuran 10GB, kosong Opsi qemu -m 2048 # RAM -cdrom img.iso # berkas ISO -hda hda.img # hdd virtual -hdb hdb.img # hdd virtual kedua -boot d # booting ke hdd -boot c # booting ke cdrom -enable-kvm # aktifkan kvm -vnc :1 # akses via vnc vncviewer :1 # akses vnc Komunikasi Jika ingin berkomunikasi dengan host, gunakan IP 10.https://aguno.xyz/post/2015/04/10/git-checkout--detach/Fri, 10 Apr 2015 12:00:00 +0000https://aguno.xyz/post/2015/04/10/git-checkout--detach/Coba perhatikan alur git berikut ini : git fetch upstream git checkout upstream/master hack hack hack git add --all git commit -m "first hack" git checkout upstream/other branch hack hack hack Nah, apakah bisa balik ke “first hack”? Bisa! Jadi selama ini saya sering kecolongan setelah langkah ke 6, mengira commit “first hack” sudah musnah dan akhirnya mengetik ulang. Tapi sebenarnya tidak. Kuncinya, kita belum kehilangan command history di shell saat commit.https://aguno.xyz/post/2015/03/30/stream-di-nodejs-1/Mon, 30 Mar 2015 12:00:00 +0000https://aguno.xyz/post/2015/03/30/stream-di-nodejs-1/Saya baru beberapa bulan bermain-main dengan NodeJS, namun baru belakangan dapat pencerahan mengenai apa dan bagaimana sih stream itu. Jadi mari saya tulis di sini supaya : Saya lupa dan kemudian cepat ingat Yang belum paham jadi cepat paham Misal kita punya dua ember : ember A dan ember B. Ember A posisinya lebih tinggi satu meter dari ember B, dan berjarak satu meter juga. Ilustrasi | A | |___| | B | |___| Ember A memiliki isi seliter air.https://aguno.xyz/post/2015/03/25/mengapa-lebih-baik-menyimpan-waktu-dalam-utc/Wed, 25 Mar 2015 12:00:00 +0000https://aguno.xyz/post/2015/03/25/mengapa-lebih-baik-menyimpan-waktu-dalam-utc/UTC adalah Coordinated Universal Time. Singkatannya kurang tepat ya, eh? UTC menjadi standar dunia dalam penetapan waktu secara universal, bukan zona waktu. Bukan UTC Sekarang kamu ada di Bogor, menginput data suatu kejadian yang terjadi di Bogor (WIB) dalam informasi waktu seperti berikut : 2 Agustus 1992 Jam 05:00 Kemudian, data tersebut dibuka di Sulawesi, yang muncul adalah 2 Agustus 1992 Jam 05:00 Seharusnya direpresentasikan dalam WITA sebagai 2 Agustus 1992 Jam 06:00https://aguno.xyz/post/2015/03/19/re.sign/Thu, 19 Mar 2015 12:00:00 +0000https://aguno.xyz/post/2015/03/19/re.sign/Jika saya ditanya, mengapa saya berhenti dari pekerjaan sebelumnya? Saya mungkin tidak akan langsung menjawab, mesti merenung-renung. Sebelumnya saya sudah pernah mengundurkan diri dua kali dari sebuah pekerjaan yang jangka bekerjanya kisaran 1 sampai 2 tahun. Yang pertama, karena pekerjaannya overwork. Saya sering lembur tanpa bayaran dan sulit mendapatkan cuti. Yang kedua, saya berhenti karena menemukan pekerjaan yang prospeknya lebih baik, yaitu dikontrak secara internal di sebuah kantor pemerintahan. Pekerjaan pertama dan kedua itu sama-sama pekerjaan yang saya senangi.https://aguno.xyz/post/2015/03/03/catatan-pemaket-blankon-1/Tue, 03 Mar 2015 12:00:00 +0000https://aguno.xyz/post/2015/03/03/catatan-pemaket-blankon-1/Terlebih dahulu, penuhi beberapa syarat. Seduh kopi. bzr branch https://dev.blankon.id/browser/tambora/blankon-installer dpkg-checkbuilddeps Pasang paket dependensi. Ngoprek.

Skrip untuk mengolah animasinya benar-benar menarik. Tapi yang bikin frustasi adalah saat mengujinya. Ada 3 cara menguji plymouth : Pakai komputer beneran Pakai komputer virtual Pakai plugin X11 (paling cepat sekaligus menyebalkan) Cara ketiga benar-benar cepat. Sunting kode, jalankan, sunting kode, jalankan. Langsung tampil, tapi ada kalanya bikin X kres. Ini yang bikin pusing. Jadi langkah aman saya dari awal sampai akhir adalah : pasang plymouth-x11 dan plymouth-theme-script menyunting berkas plymouth-thme-script mengganti pilihan plymouth ke tema script : update-alternatives --config default.https://aguno.xyz/post/2015/01/20/kopi-instan-yang-pas/Tue, 20 Jan 2015 12:00:00 +0000https://aguno.xyz/post/2015/01/20/kopi-instan-yang-pas/Sebenarnya kopi instan itu enak, hanya saja, mereka terlalu banyak mengandung gula. Terlalu manis. Kalau wanita sih tidak apa, tapi kalau kopi, ini kurang bisa ditoleransi. Bagaimana supaya rasanya minimal mirip kopi di Sevel atau Starbak? Eksperimen saya dimulai dengan indocafe coffeemix. Tuangkan seluruh isi saket kopi ke dalam cangkir. Tuangkan 1/3 gelas air biasa. Bukan air panas atau dingin. Suhu biasa saja. Aduh perlahan. Sampai semuanya larut. Jangan khawatir, bubuk kopi indocafe coffeemix mudah larut.https://aguno.xyz/post/2014/12/26/yang-saya-oprek-dalam-dua-bulan-ini/Fri, 26 Dec 2014 12:00:00 +0000https://aguno.xyz/post/2014/12/26/yang-saya-oprek-dalam-dua-bulan-ini/bulan sejak tulisan terakhir, saya menyia-nyiakan blog ini rupanya. Nah, mari saya tulis sesuatu. Mestinya, setelah ngoprek, saya menulis/mendokumentasikan. Tapi ini benar-benar sulit dilakukan. Saya akan menulis sepintas-sepinas apa yang saya oprek selama dua bulan ini : Javascript Setelah dulu nyaman di PHP, kemudian pindah ke Python karena diolok-olok dibujuk Deni Marswandi, sekarang sibuk main js. Berbeda dengan kebanyakan bahasa pemograman, Js itu async, jika ada 3 baris kode yang sejajar, maka ketiga-tiganya dijalankan bersamaan.https://aguno.xyz/post/2014/11/02/pindah-ke-ghost/Sun, 02 Nov 2014 12:00:00 +0000https://aguno.xyz/post/2014/11/02/pindah-ke-ghost/Sekalian sebagai hadiah ulang tahun untuk aktivitas ngeblog (November 2008 - November 2014), akhirnya saya benar-benar pindah ke Ghost. Blog lama diletakkan di pdft.net/wp/. Saya sengaja tidak mengimpor data dari wordpress ke sini karena hasilnya belum begitu sempurna, terutama bagaimana proses impornya mengabaikan bentuk paragraf dari wordpress. Belum ada waktu buat ngoprekin. Dan tujuan semula blog ini akhirnya ikut berubah. Bukan saja untuk catatan ngoprek, tapi tentang apa saja. Untuk anda yang ingin mencicipi ghost, barangkali dapat mencoba dengan panduan berikut.https://aguno.xyz/post/2014/10/30/ngeblog-dengan-ghost-di-heroku-gratis/Thu, 30 Oct 2014 12:00:00 +0000https://aguno.xyz/post/2014/10/30/ngeblog-dengan-ghost-di-heroku-gratis/Halo, Pada tulisan ini, saya “meng-Indonesia-kan” panduan yang tertulis di tautan berikut : http://blog.johnny.io/how-to-get-ghost-running-on-heroku-for-free/ Tulisan ini akan memandu anda bagaimana membangun blog berbasis Ghost dan menumpangkannya di Heroku. Gratis! Apa itu Ghost? Tidak seperti platform blogging pada umumnya, Ghost bukan berbasis PHP, melainkan Node.Js. Node.Js adalah platform untuk membangun aplikasi real time, asynchronous, event-driven, menggunakan bahasa Javascript dan engine Javascript v8 dari Google Chrome. Ghost sangat keren, dirancang untuk ngeblog, tidak yang lain.https://aguno.xyz/post/2014/10/27/bimbang/Mon, 27 Oct 2014 12:00:00 +0000https://aguno.xyz/post/2014/10/27/bimbang/Ketemu sama teknologi baru, saya ini mudah bimbang. Sekarang lihatlah Ghost, platform untuk ngeblog yang katanya Wordpress Killer. Just a blogging platform, katanya? Bullshit itu, terlalu merendah. :D Blog ini memang berjalan di atas ghost. Kelihatan biasa saja ya. Tunggu deh sampai lihat dalemannya bagaimana. Dan saya pun bimbang, setelah ngeblog dengan Wordpress sejak tahun 2008 (sekarang blog.pdft.net), perlukah saya bermigrasi ke Ghost? Awalnya, blog ini saya dedikasikan untuk catatan ngoprek saja (dan dengan tulisan ini, dedikasi tersebut dilanggar).https://aguno.xyz/tech_talks/Mon, 01 Jan 0001 00:00:00 +0000https://aguno.xyz/tech_talks/ Why Local Tech Communities are Important and How to Run Them - Lightning Talk Session at IDSW 2025 @ Jakarta (2025) Crafting a native GNOME app for Ubuntu and ship it via Snap - UbuCon Asia 2023 (LOUCA 2023) @ Surakarta, Indonesia (2023) - Youtube Ngoprek Mozilla Firefox, Siklus kontribusi kode ke Mozilla Firefox dari ujung ke ujung - Moztalk Opensource Day @ MozSpace Jakarta, Indonesia (2020) IRGSH - OpenSUSE Asia Summit 2019 @ Bali, Indonesia (2019) Monorepo - Lombok Dev Meetup 2019 @ Lombok, Indonesia (2019) Revolusi Kultur Devops - Lombok Dev Meetup 2017 @ Lombok, Indonesia (2017) Happy-CRUD - JakartaJS @ Jakarta, Indonesia (2016) PKIWebSDK: Pustaka JavaScript untuk Aplikasi berbasis PKI - IDSECONF 2016 @ Malang, Indonesia (2016) BlankOn Installer - GNOME Asia 2015 @ Depok, Indonesia (2015)
