Facts about Linux
Every time you switch on your computer, you see a screen where you can perform different activities like write, browse the internet or watch a video. What is it that makes the computer hardware work like that? How does the processor on your computer know that you are asking it to run a mp3 file?
Well, it is the operating system or the kernel which does this work. A kernel is a program at the heart of any operating system that takes care of fundamental stuff, like letting hardware communicate with software.
So, to work on your computer you need an operating system (OS). In fact, you are using one as you read on your computer. Now, you may have used popular OS’s like Windows, Apple OS X but here we see what Linux is and what benefits it offers over other OS choices.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Presentation1
1. Linux (diucapkan ˈlɪnəks atau /ˈlɪnʊks/)[1] adalah nama yang
diberikan kepada sistem operasi komputer bertipe Unix. Linux
merupakan salah satu contoh hasil pengembangan perangkat
lunak bebas dan sumber terbuka utama. Seperti perangkat
lunak bebas dan sumber terbuka lainnya pada umumnya, kode
sumber Linux dapat dimodifikasi, digunakan dan didistribusikan
kembali secara bebas oleh siapa saja.[2]
Nama "Linux" berasal dari nama pembuatnya, yang
diperkenalkan tahun 1991 oleh Linus Torvalds. Sistemnya,
peralatan sistem dan pustakanya umumnya berasal dari sistem
operasi GNU, yang diumumkan tahun 1983 oleh Richard
Stallman. Kontribusi GNU adalah dasar dari munculnya nama
alternatif GNU/Linux.[3]
2. Linux telah lama dikenal untuk penggunaannya di server, dan
didukung oleh perusahaan-perusahaan komputer ternama
seperti Intel, Dell, Hewlett-Packard, IBM, Novell, Oracle
Corporation, Red Hat, dan Sun Microsystems. Linux digunakan
sebagai sistem operasi di berbagai macam jenis perangkat
keras komputer, termasuk komputer desktop, superkomputer,[4],
dan sistem benam seperti pembaca buku elektronik, sistem
permainan video (PlayStation 2, PlayStation 3 dan XBox[5]),
telepon genggam dan router. Para pengamat teknologi
informatika beranggapan kesuksesan Linux dikarenakan Linux
tidak bergantung kepada vendor (vendor independence), biaya
operasional yang rendah, dan kompatibilitas yang tinggi
dibandingkan versi UNIX tak bebas, serta faktor keamanan dan
kestabilannya yang tinggi dibandingkan dengan sistem operasi
lainnya seperti Microsoft Windows.
3. Ciri-ciri ini juga menjadi bukti atas keunggulan
model pengembangan perangkat lunak sumber
terbuka (opensource software).
Sistem operasi Linux yang dikenal dengan istilah
distribusi Linux (Linux distribution) atau distro Linux
umumnya sudah termasuk perangkat-perangkat
lunak pendukung seperti server web, bahasa
pemrograman, basisdata, tampilan desktop (desktop
environment) seperti GNOME,KDE dan Xfce juga
memiliki paket aplikasi perkantoran (office suite)
seperti OpenOffice.org, KOffice, Abiword, Gnumeric
dan LibreOffice.
4. Pembuat Linux OS
Linus Torvalds
Linus Torvalds dilahirkan di Helsinki, Finlandia, pada tanggal 28
Desember 1969. Dalam usianya yang ke 10, Linus mulai berkecimpung
di dalam pemograman komputer, dengan menggunakan komputer milik
kakeknya, Commodore VIC-20. Komputing pun menjadi hobinya. Pada
tahun 1988 Linus diterima menjadi mahasiswa di University of Helsinki,
Finlandia. Pada tahun 1990, Linus memulai kelas pemograman C
pertamanya.
5. Pada April 1991, Linus Torvalds, seorang mahasiswa berusia 21 tahun dari
Universitas Helsinski, Finlandia mulai memikirkan sesuatu ide sederhana untuk
suatu Sistem Operasi. Ia memulai dengan task switcher dalam Bahasa Rakitan x86
pada Intel 80386 dan sebuah driver Terminal. Pada 25 Agustus 1991, Torvalds
memposting sebuah pesan di comp.os.minix, sebuah newsgroup di Usenet:
I'm doing a (free) operating system (just a hobby, won't be big and professional
like gnu) for 386(486) AT clones. This has been brewing since April, and is starting
to get ready. I'd like any feedback on things people like/dislike in minix, as my OS
resembles it somewhat (same physical layout of the file-system (due to practical
reasons) among other things). I've currently ported bash(1.08) and gcc(1.40), and
things seem to work. This implies that I'll get something practical within a few
months [...] Yes - it's free of any minix code, and it has a multi-threaded fs. It is NOT
portable (uses 386 task switching etc), and it probably never will support
anything other than AT-harddisks, as that's all I have :-(.
[...] It's mostly in C, but most people wouldn't call what I write C. It uses every
conceivable feature of the 386 I could find, as it was also a project to teach me
about the 386. As already mentioned, it uses a MMU, for both paging (not to disk
yet) and segmentation. It's the segmentation that makes it REALLY 386 dependent
(every task has a 64Mb segment for code & data - max 64 tasks in 4Gb. Anybody
who needs more than 64Mb/task - tough cookies). [...] Some of my "C"-files
(specifically mm.c) are almost as much assembler as C. [...] Unlike minix, I also
happen to LIKE interrupts, so interrupts are handled without trying to hide the
reason behind them.

26. Aplikasi Adalah subkelas dari perangkat lunak (software) yang memanfaatkan
kemampuan komputer langsung untuk melakukan suatu tugas yang diinginkan
pengguna. Contoh utama aplikasi adalah pengolah kata ( Ms. Word ), Lembar
kerja, dan pemutar media ( Windows Media Player )
OS/ Sistem Operasi Adalah seperangkat program yang mengelola sumber daya perangkat
keras komputer dan menyediakan layanan umum untuk aplikasi. OS adalah jenis yang
paling penting dari perangkat lunak sistem dalam sistem komputer. Tanpa sistem operasi,
pengguna tidak dapat menjalankan program aplikasi pada komputer mereka, kecuali
program aplikasi booting. Contoh OS adalah Linux, Android, Symbian, Mac OSX, Microsoft
Windows
Kesimpulanya :
Aplikasi, Program, dan OS merupakan software. Aplikasi itu tersusun atas program (
instruksi-instruksi sehingga bisa digunakan oleh pengguna), dan semuanya itu tidak
bisa dijalankan apabila tidak ada OS.
