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 This constraint allows unpublished products (is_published=False) to have a price of 0.


🇺🇿: soon … 😉

OSI Model chiqdi 🎉

Qo'llanma yozishda ba'zi xatoliklarga yo'l qo'ygan bo'lishimiz mumkin.

Iltimos uni izohlarda yozib to'g'irlab keting.

Qatiyatli bo'ling va o'rganishda charchamang.

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

Skills Outlast Jobs: Jobs are not important, but skills will always be.

1. Problem Solving and Critical Thinking
1. Ability to determine where to start, how to proceed step by step, and the ability to plan and prioritize overall work.
2. Ability to identify the source of the problem. Having systematic thinking (seeing the whole picture) to solve the problem. Take the right inputs and generate the right outputs.
3. Ability to ask GOOD questions: What/How/Why?
4. Ability to consider trade-offs and provide various solutions to problems (but this comes from experience, from knowledge, where to get that knowledge? Search the internet and talk with experts).
5. Bias towards action. Don’t wait until someone does something. Find the ways how YOU can make an impact.
6. Searching for the right information fast from the right sources (from the right people).
7. Being proactive.

2. Communication and Presentation skills
1. Ability to deliver the right information in the proper format to the right audience. Give what the people want (answer their questions beforehand, we talk differently to managers, developers, and non-IT people).
2. Skill to control the level of abstraction during the conversation (Just like OOP principle). Talking about trade-offs.
3. Ability to make good presentations. Showcasing the work in various formats (presentations, graphs, activity diagrams).

3. IT-related skills
1. Doing work fast & efficiently using different AI-tools.
2. Automating routine work.
3. Coding skills to build something new and deliver value.

4. Creativity and Innovation
1. Even if the technology will advance, we will still need more people who build something new, develop new ideas, products/services.

5. Learning things fast and being agile
1. Adapting to changes quickly.
2. Knowing how to learn (learn from courses, books, articles, conferences, discussion groups, talking with experts). If you are an IT-guy, then learn by doing.

6. Ability to work in a team, managing the team.

7. Emotional intelligence. Demonstrating empathy, rationality, and lack of bias. Analyzing personal actions. Overall, be a good person and a positive contributor to society.
