So’ngi 2 oy stresslarga boy o’tdi 🤯

Berilgan loyha hajmi kattaroq edi.

Bunga:

- Machine Learning - model train qilish
- FastAPI da ko’targan microserviceni refactoring qilish o’rniga GO’da qayta yozib chiqish
- Bazaga hitlarni kamaytirish uchun soft SQL surovlar yozish
- M.U.N.I.S kabi boshqa davlat loyhalari biLan integrasiyalash
- Search tezlashtirish maqsadida Elastic Search ishlatish
- Admin role uchun esa VueJs'da Frontent qismini ishlab chiqish
- Va boshqalarga …

majbur bo’ldim …🤦‍♂️

Shu faqat Jiramda biroz tasklar qoldi (DB sharding, Docker Swarm)

Natijada esa o’qiyman deb saqlab qo’ygan kitoblarim va video darslarim ham tuxtab qoldi 😕

Xullas loyha uchun deadline belgilanilayotganda etiborli bo’lishimiz zarur 😑

P.s Loyhani MVP qilib topshirishim bilanoq Ochiq tabiat quynida sizlar bilan picnic 🧺 qilish niyat qilib quydim. Insha’Allah)

Keladiganlar bormi ?

p.s Bar bir bazilarda bu mavzularda tushunmovchiliklar, ikkilanishlar bo'lmoqda 'Deep dive' qilib ko'rish zarur ... (Junior-Middle Interview results ... )

Ho’p demak … 🎊

Bu tema yana qayta ochilmoqda tayor turamiza. Postni tanish middle leveldagi (ayniqsa FullStack bo’lsa +) dasturchi tanishlarga yuborib quying tez orada kanalarda ham chiqib qoladi to’liq talablar va e’lon postlari 😉

Go with live reload (in docker)

p.s kerak bo'lib qolar

Sizda bir necha pdf formatidagi filelar va ichida malumotlari mavjud.

example:
* devops_names.pdf (10_000_000 pages)
* programmers_names.pdf (100_000_000 pages)
…

Vazifa shundan iboratki agar user John deb qidirganida barcha faylardan John qatnashgan page raqamlar qaytaradigan search engine qilish.

Example:
Input: John Washington
Output:
[
{
pdf_name:[ page_no1, page_no2]
},

{
devops_names:[ 12, 854]

Concurrency vs Parallelism bittami?

Disclaimer — Bu ikki atamani o’zbekcha tarjimasini qidirgan edim, ikkalasini ham bir xil, parallellik deb tarjima qilib berdi. Shuning uchun asl holatida yozaman.

Concurrency va parallelism o’xshash, ikkisi ham bir necha tasklarni bir vaqtda bajarish uchun mo’ljallangan bo’lsada, ular orasida yetarlicha farqlar bor.

Sizda bajaralishi kerak bo’lgan 10 ta task va uni bajarish uchun esa 1 dona CPU bor. Concurrency barcha 10 tasklarni ma’lum bir vaqt oralig’ida, tasklarni almashtirgan holatda faqat bitta taskni bajaradi. 1 dona CPU (protsessor) 10 ta taskni almashtirgan holatda bajaradi, bu esa xuddiki 10 ta task bir vaqtda(multitasking) bajarilayotgandek illuziya beradi.

Concurrency I/O bound operatsiyalarida juda foydali hisoblanadi. Chunki qaysidir task I/O bound kutish holatida bo’lsa, context switch boshqa taskni bajarib turadi, bu esa dastur ishini tezlashtiradi.

Tasavvur qiling, siz yana oshxonadasiz, va bu safar makaron pishiryapsiz.

Sizda quyidagi tasklar bor:
1) Sabzavotlarni tozalash va to’g’rash
2) Makaronni suvda qaynatish
3) Qayla tayyorlash(piyoz, pomidor yordamida)

Agar siz sinxron tarzda ishlasangiz, bularni ketma-ketlikda bajarishingiz kerak edi. Avval sabzavotlarni tozalab, to’g’raysiz(15 minut). Keyin Makaronni suvda qaynashini kutasiz(25 minut) va oxirida esa qaylani tayyorlab(20 minut), barchasini aralashtirasiz. Sinxron tarzda siz makaron tayyorlash uchun, 1 soat sarfladingiz.

Endi shuni, Concurrency tarzida amalga oshiradigan bo’lsak, jarayon quyidagicha ko’rinish oladi:
Makaronni suvda qaynatishga qo’yib, sabzavotlarni to’graysiz(15 minut) va qayla tayyorlashni ham boshlab qo’yasiz. Ora-orada qaylani ham aralashtirasiz va yana sabzavotlarni to’g’rashda davom etasiz(Task switching). Bu esa resurs va vaqtdan unumli foydalanishga olib keladi. Kompyuter CPU si ham aynan shunday task switching tarzida ishlaydi.

🔥 Django Models/Advanced tip

🇺🇸: When you need to enforce data integrity constraints in your Django models, CheckConstraint is your go-to tool.

The first CheckConstraint named "valid_price" ensures that the price of a product is non-negative.

The second CheckConstraint named "published_products_have_positive_price" enforces that if a product is published (is_published=True), it must have a positive price. This constraint allows unpublished products (is_published=False) to have a price of 0.

Interviewerni lol qoldirish 👆

Rostan ham ko’p dasturchilar kunlik ishidan tashqari biror foydali narsa bilan shug’ullanishmaydi. Soat 18:00dan keyin bu sizning vaqtingiz, uni yana kompaniya ishini qilib o’tkazmang.

Shu borada 5-6ta idealar:
— Yangi texnologiyalar o’rganing
— O’zingizni startupchalaringizni boshlang. 99.99% fail bo’ladi, lekin ko’p narsa o’rganasiz (hech bo’lmasa shu bilan keyingi intervieweringizni lol qoldirasiz 😁)
— Mentorlik qiling, Programming clubga qo’shiling
— Competitive programming qiling (leetcode, hackerrank, etc)
— Sport bilan shug’ullaning
— Open source contribution qiling
— Blog yuruting
— va hokazo
