💡 مقایسه‌ی پارادایم‌های برنامه‌نویسی — از Flow-Based تا State-Centric

در مسیر تحول برنامه‌نویسی، از تفکر flow-based با تکیه بر functionها، رفتیم به سمت ساختارهای state-centric و assignment-driven — و در این بین، شاید چیزی مهم مثل وضوح جریان داده رو از دست دادیم.

۱- Functional Programming (FP) — function-driven، flow-based

✅ توابع هسته‌ی اصلی محاسبات هستن.
✅ توابع به‌عنوان داده در نظر گرفته می‌شه؛ می‌تونه ترکیب بشه.
✅ تمرکز روی جریان صریح داده بین functionهاست.
✅ ساده، قابل پیش‌بینی، بدون state پنهان.
⚠️ مدل‌سازی سیستم‌های واقعی و stateful در این پارادایم محدودتره.

۲- Object-Oriented Programming (OOP) — state-centric، assignment-driven

✅ توابع مرتبط به‌همراه state مشترک در قالب objectها قرار می‌گیرن.
✅ باعث modularity و استفاده‌ی مجدد از کد می‌شه.
⚠️ ولی جریان هندل کردن یک سناریو implicit می‌شه — توی methodها و تغییرات داخلی state پنهانه.
⚠️ منطق حول assign و تغییر وضعیت- change state- می‌چرخه، نه حول جریان.

۳- Actor Model — agent-centric، message-driven

✅ پارادایم OOP رو یه قدم جلوتر می‌بره: objectها به agentهای مستقل تبدیل می‌شن.
✅ این agentها فقط با پیام‌های async با هم حرف می‌زنن.
✅ برای سیستم‌های concurrent و توزیع‌شده عالیه.
⚠️ اما باز هم جریان داده پراکنده و پنهانه — در زنجیره‌های پیام و actorهای جدا.
--------------------------------------

👉 در این مسیر، از flow-based logic به سمت ساختار و مقیاس‌پذیری رفتیم — ولی اغلب با هزینه‌ی از دست دادن وضوح جریان داده.

🧭 آیا می‌تونیم دوباره بین این‌ها تعادل ایجاد کنیم؟

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.

Telegram Q&A
Q: How does hottg.com work?
Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Q: What is Telegram? What do I do here?

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.

Q: Who is Telegram for?

Telegram is for everyone who wants fast and reliable messaging and calls. Business users and small teams may like the large groups, usernames, desktop apps and powerful file sharing options. You can appoint admins with advanced tools to help these communities prosper in peace. Public groups can be joined by anyone and are powerful platforms for discussions and collecting feedback.In case you're more into pictures, Telegram has animated gif search, a state of the art photo editor, and an open sticker platform (find some cool stickers here or here). What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Q: How is Telegram different from WhatsApp?

Unlike WhatsApp, Telegram is a cloud-based messenger with seamless sync. As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure. On top of that, Telegram is free and will stay free — no ads, no subscription fees, forever.

Q: Can I make calls via Telegram?

Yes! Voice calls are currently available to users around the world.

Many modern travelers appear to struggle with managing various aspects of their finances simultaneously while abroad, such as banking, budgeting, investing, trading, and saving. It is important to have apps installed on the device that will help you carry out these necessary tasks.
