Den nye operativsystem Essence er tilg\u00e6ngelig til indledende test, leveret med sin egen kerne og brugergr\u00e6nseflade. Projektet er blevet udviklet af en entusiast siden 2017, skabt fra bunden og er bem\u00e6rkelsesv\u00e6rdigt for sin unikke tilgang til at opbygge skrivebordsmilj\u00f8et og den grafiske stak. En af de mest markante funktioner er muligheden for at opdele vinduer i faner, hvilket giver mulighed for at arbejde i \u00e9t vindue med flere programmer og gruppere applikationer i vinduer afh\u00e6ngigt af de opgaver, der skal l\u00f8ses. Projektkoden er skrevet i C++ og distribueres under MIT-licensen.

\"Essence<\/center> <\/p>\n

Vinduesmanageren arbejder p\u00e5 niveauet for operativsystemets kerne, og gr\u00e6nsefladen oprettes ved hj\u00e6lp af et eget grafisk bibliotek og en programmatisk vektor-motor, der underst\u00f8tter komplekse animerede effekter. Gr\u00e6nsefladen er helt vektorbaseret og skaleres automatisk til alle sk\u00e6rmopl\u00f8sninger. Al information om stilarter opbevares i separate filer, hvilket g\u00f8r det nemt at \u00e6ndre udseendet af applikationerne. For grafisk rendering anvendes OpenGL-kode fra Mesa. Der er support for flere sprog, og FreeType og Harfbuzz bruges til rendering af skrifttyper.

\"Essence<\/center> <\/p>\n

Kernen inkluderer en opgaveplanl\u00e6gger med st\u00f8tte til flere niveauer af prioriteter, et hukommelsesstyringssystem med st\u00f8tte for delt hukommelse, mmap og en multitr\u00e5det hukommelsessidebehandler, et netv\u00e6rksstak (TCP\/IP), et lydsystem til blanding af lyde, VFS og filsystemet EssenceFS med et separat lag til data caching. Udover dets eget filsystem tilbydes der drivere til Ext2, FAT, NTFS og ISO9660. Muligheden for at udvide funktionalitet i moduler underst\u00f8ttes, med evnen til at indl\u00e6se s\u00e5danne moduler efter behov. Driverne er forberedt til ACPI med ACPICA, IDE, AHCI, NVMe, BGA, SVGA, HD Audio, Ethernet 8254x og USB XHCI (lagringsenheder og HID). <\/p>\n

Kompatibilitet med tredjepartsapplikationer opn\u00e5s gennem en POSIX-lag, der er tilstr\u00e6kkelig til at k\u00f8re GCC og en del af Busybox-v\u00e6rkt\u00f8jerne. Blandt de portede applikationer til Essence bem\u00e6rkes Musl C-biblioteket, Bochs emulator, GCC, Binutils, FFmpeg og Mesa. Blandt de grafiske applikationer, der er oprettet specifikt til Essence, er filh\u00e5ndtereren, teksteditoren, IRC-klienten, billedfremviser og systemmonitoren.

\"Essence<\/center> <\/p>\n

Systemet kan k\u00f8re p\u00e5 for\u00e6ldet udstyr med mindre end 64 MB RAM og optager omkring 30 MB diskplads. For at spare ressourcer k\u00f8rer kun den aktive applikation, mens alle baggrundsprogrammer s\u00e6ttes p\u00e5 pause. Opstart tager blot et par sekunder, og nedlukning sker n\u00e6sten \u00f8jeblikkeligt. Projektet offentligg\u00f8r dagligt nye f\u00e6rdige builds, der er velegnede til test i QEMU.
