So'ngi payitlarda juda ko'p retro computing forumlarda aylanib yuribman. O'zim uchun nafaqat qiziq insonlar balki juda ko'p g'oya va fikrlar olyabman.

Masalan Sun ultra 5 computer haqidagi qiziq video

Retrocomputing qiziq ekani sababi nostalgiya emas balki aslida juda ko'p juda qiziq kashfiyot va texnalogiyalar turli sabablarga ko'ra tashlab yuborilgan va bularni o'rganib eng kamida ilhomlanish mumkin. Ko'p kompyuter foydalanuvchilari xatto juda ham ko'p dasturchilar uchun ham o'zlari ishlatadigan qurilmalar blackbox bo'lib yotibti. Eksiroq modellar misolida esa o'rganish oson juda ko'p qurilmalar tuzilishini.

Unix juda ko'p innovatsiyalar qilgan.
Multi tasking, C dasturlash tili, hierarchical file system. Bizga yetib kelgan va juda ko'pchilik bilgan narsalardan.

Undan tashqari user expirence va dev env borasida ham eng birinchi turli experiment va implementatsiyalar unixda qilingan.

Shu o'rinda eslash kerkki bu g'oya va texnalogiyalar ustida ishlagan muxandis va professorlar Turing mukofotini olishgan.

Qiziq maqola, qiziq tajriba. Yuristlar Open source tizimlardan foydalanishi. Free self hosted software g’oyasiga amal qilishlari juda ajoyib!

wikida aylanib yurganimda chiqib qoldi.

Bizni error detectorni yangi versiyasida Hardware problemlarni detect qilish yaxshilanadi.

Bazi muammolarni kerneldagi printlarga detect qilsa bo'ladigan qilyabman :)

Bu yechimga kelish juda ham qiziq bo'ldida. Hullas fedoradagi abrt kernel oops detectorni ko'rib o'tirgan edim manashu codeni topib oldim. Pastroqda esa bazi reflar keltirilgan masalan bunaqa arch/arc/kernel/traps.c

Kegin o'ylanib qoldim, kernelni clone qilib shunchaki kerak narsani search qilsamchi ?

Ideya juda oddiy, manashunaqa patternlar yozib chiqaman: hardware error gpu error, gpu hang vaxakazolar.

manashunaqa bruteforcedan kegin qiziq narsalar chiqa boshladi :) manashunaqa qilib uje tushunib oldim hardware, driver muammolari chiqsa qanday aniqlashni. Kegin yana chuqurroq qarashni boshladim va yana ancha narsalar topib oldim, masalan fs, disk health mavzularini ham.

Endi errorlarni indexlab ketish kerak. Kegin manashular asosida biror muammo chiqsa qanday hal etsa bo'ladi yoki muammoning sababi xaqida izlanishlar qisak bo'ladi. Masalan GPU hang nimaga sodir bo'ldi ? kabi savollar bo'lsa eng kamida taxminiy javoblar balki yechimlar ham bo'lishi uchun.

bugun yakshanbalik qildim.

io_uring aynan nvme storagelarda yanada kuchli bo'ladi degan taxminim bor edi.

Uje bu mavzularda juda qiziq narsalar qilishgan ekan.

https://xnvme.io/

https://spdk.io/

io_uring uje juda ko'p joyda bor va nvmelar ham. Allaqachon file systemlarda ham nvmega aloqador ancha optimizatsiyalar qilingan Masalan buyoqda: https://gist.github.com/bradjohnl/afe38e82dc9197bad5221c4c7ea3b825

Shu o'rinda zamonaviy DBlar ham turli optimizatsiyalarni qilishgan.

Ammo hamma applicationlarda ham bunday optimizatsiyalar mavjud emas xozircha, manda anchadan buyon high performance storage synchronization mavzusida qilinadigan ishlar yeg'ilib qolgan. Bugun ertalabdan shular uchun fundament yeg'ishni boshladim va manashu temalarni topib oldim :)

io_uringni network traffic handling uchun ishlatish fikriga skeptikman biroz. Ammo aynan storage systems va minglab mayda io operations bo'lsa liburing pobeda bo'lishi mumkin.

Agar kimgadir umumiy qiziq bo'lsa: https://unixism.net/loti/index.html

Your Usafe C

Shunga haskellda yozamanda. Uyoqda mabjuriy emas }{uyna qavslar

kernel ichidagi timeout funksionalardan biri :)

Bunaqa narsalarni ijod qilish uchun bilmadim nima yeyish kerak, nima chakish kerak ammo so fucking impressive 🥺
