Nix on SHARCNET
Nix on SHARCNET Tyson Whitehead May 14, 2015 Nix Overview An enterprise approach to package management I a package is a specific piece of code compiled in a specific way I each package is entirely self contained and does not change I each users select what packages they want and gets a custom enviornment https://nixos.org/nix Ships with several thousand packages already created https://nixos.org/nixos/packages.html SHARCNET What this adds to SHARCNET I each user can have their own custom environments I environments should work everywhere (closed with no external dependencies) I several thousand new and newer packages Current issues (first is permanent, second will likely be resolved) I newer glibc requires kernel 2.6.32 so no requin I package can be used but not installed/removed on viz/vdi https: //sourceware.org/ml/libc-alpha/2014-01/msg00511.html Enabling Nix Nix is installed under /home/nixbld on SHARCNET. Enable for a single sessiong by running source /home/nixbld/profile.d/nix-profile.sh To always enable add this to the end of ~/.bash_profile echo source /home/nixbld/profile.d/nix-profile.sh \ >> ~/.bash_profile Reseting Nix A basic reset is done by removing all .nix* files from your home directory rm -fr ~/.nix* A complete reset done by remove your Nix per-user directories rm -fr /home/nixbld/var/nix/profile/per-user/$USER rm -fr /home/nixbld/var/nix/gcroots/per-user/$USER The nix-profile.sh script will re-create these with the defaults next time it runs. Environment The nix-env commands maintains your environments I query packages (available and installed) I create a new environment from current one by adding packages I create a new environment from current one by removing packages I switching between existing environments I delete unused environements Querying Packages The nix-env {--query | -q} .. -

1. Mengapa GIMP & Inkscape Tidak Punya Warna
Paten Software Merugikan Komunitas Free Software Bismillahirrahmanirrahim. Copyright © 2016 Ade Malsasa Akbar <[email protected]> Tulisan ini berbicara mengenai bahaya paten software yang mengakibatkan banyak Free Software mengalami kekurangan fitur dibanding software proprietari komersial. Tulisan ini awalnya berjudul Mengapa Free Software Mengalami Kekurangan Fitur? tetapi diubah pada 16 Maret 2016 menjadi berjudul yang sekarang. Tulisan ini diharapkan membangkitkan kesadaran setiap orang terhadap perlunya Free Software. Tulisan ini disusun dalam format tanya jawab atau FAQ supaya tepat sasaran dan mudah dimengerti. Saya bukan hanya menulis ini untuk mereka yang bertanya-tanya kenapa Free Software seperti LibreOffice, GIMP, Inkscape, ODF, dan OGG Vorbis mengalami kekurangan fitur. Namun juga saya meniatkan tulisan ini sebagai pengantar buat siapa saja yang hendak menggunakan Free Software, baik pengguna baru maupun yang sudah lama. 1. Mengapa GIMP & Inkscape tidak punya warna Pantone? Karena Pantone Color Matching telah dipatenkan1. Hanya pemilik paten tersebut yang berhak membuat implementasi Pantone di dalam software. Konsekuensinya, GIMP (dan free software lainnya) dilarang membuat fitur Pantone ke dalam software. 2. Mengapa Linux Mint menyediakan versi no-codec? Karena versi no-codec2 dibuat untuk negara Jepang yang di sana MP3 dipatenkan. Pada dasarnya tidak boleh mendistribusikan codec MP3 di Jepang kecuali pemegang asli paten MP3. Berlaku juga untuk negara Amerika Serikat dan Uni Eropa. 3. Mengapa Linux Mint menyertakan codec? Karena versi Linux Mint yang menyertakan codec itu ditujukan untuk semua negara yang di sana codec MP3 tidak dipatenkan. Linux Mint (yang memuat codec) tidak didistribusikan di negara Jepang, Amerika Serikat, dan Uni Eropa3 karena di sana MP3 telah dipatenkan. Kenyataan ini yang tidak banyak diketahui. -
