В прошлых постах я показывал зарплаты как их обычно пишут в вакансиях — gross (до налогов и удержаний). Но “сколько останется на руки” сильно зависит от страны, семейного статуса, региона и структуры удержаний.

🇪🇺 В Европе из зарплаты часто уходят подоходный + соцвзносы (в т.ч. медицина), поэтому разница gross→net может быть ощутимой.
🇺🇸В США, кроме федерального/штатного налога, есть FICA (Social Security + Medicare) и часто отдельная доля сотрудника за медстраховку.
🇦🇪В Центральной Азии (Персидский залив) ставки чаще ниже/плоские, но и набор соцгарантий и правила удержаний отличаются.

Карта сверху показывает верхнюю ставку (top marginal), но то, что реально остаётся “на руки”, определяется связкой: подоходный + соцвзносы + (часто) медицина/страховки. Именно из-за этого gross→net в ЕС и США может отличаться на десятки процентов даже при одинаковом “годовом окладе”.

Ниже — калькуляторы и официальные источники по 2025/2026: вбиваете доход, регион, семейный статус — и получаете прозрачный расчёт, сколько забирает государство и сколько остаётся вам. Добавил пример по Германии, чтобы было видно структуру удержаний. Хотите спорить про “социализм/равенство” — сначала посчитайте цифры.

Спасибо всем подписчикам кто комментирует, поднимает важные вопросы, подсвечивает невидимые стороны вопроса! Благодаря вам появился этот пост - расшифровка!🤝🤝🤝

In my previous posts, I showed salaries the way they’re usually listed in job postings — gross (before taxes and deductions). But how much you actually “take home” depends heavily on the country, your family status, the region, and the deduction structure.

🇪🇺 In Europe, a big chunk often goes to income tax + social contributions (including healthcare), so the gross → net gap can be significant.
🇺🇸 In the U.S., besides federal/state taxes, there’s FICA (Social Security + Medicare), and employees often pay an additional share for health insurance.
🇦🇪 In Central Asia (the Persian Gulf), rates are more often lower/flat, but the benefits package and deduction rules are different.

The map above shows the top marginal tax rate, but what you actually take home is determined by the combo of income tax + social contributions + (often) healthcare/insurance. That’s why gross → net in the EU and the U.S. can differ by tens of percent even with the same “annual salary.”

Below are calculators and official sources for 2025/2026: enter your income, region, and family status — and you’ll get a transparent breakdown of what the government takes and what you keep. I also added a Germany example so you can see the deduction structure. Want to argue about “socialism/equality”? Start by running the numbers.

Big thanks to everyone who comments, raises important questions, and highlights the hidden side of things — this “breakdown post” exists because of you! 🤝👏🔥

CCNA Quick-Revision Map

I’ve been going through a “Cisco CCNA Summary” deck that’s built for fast recall + hands-on practice — it compresses the topics you actually touch in Packet Tracer / real configs into a clean, visual flow.

What I liked most: it connects concepts → commands → verification, so you’re not memorizing in isolation.

Here are the chunks that make it bookmark-worthy:
✅ OSI 7 Layers refresher (with examples that stick)
✅ Subnetting / prefixes (the mental model + practice patterns)
✅ Core CLI muscle memory (interface, hostname, saving config, show commands)
✅ VLANs + Trunking (access vs trunk, allowed VLANs, native VLAN, dot1q)
✅ STP (roles, states, root bridge logic, PVSTP + verification)
✅ EtherChannel (LACP vs PAgP, why it matters, how to verify Po interfaces)
✅ Routing basics

Static routing (2–4 router scenarios)
Dynamic routing overview + EIGRP / OSPF step-by-step flow

The Purple Book on Cyber Security

The Purple Book on Cyber Security is built for the people in the middle: Sales, Pre-sales, and Delivery teams who need to speak security clearly, scope it correctly, and run it reliably.

What makes it different:
🟣 Beginner-friendly, practical structure

Each topic is organized as:
✅ Basics (what it is + why it matters)
✅ Sales cues (questions to ask, objections you’ll hear)
✅ Pre-sales cues (sizing, integrations, implementation steps, what can go wrong)
✅ Delivery cues (daily/weekly/monthly ops, L1/L2/L3 responsibilities, reporting & governance)

🧠 It also clarifies the foundations:
Cybersecurity vs Information Security (and why InfoSec = Cyber + Physical)
Why “Purple” matters: bridging offense (red) + defense (blue) through collaboration (Purple Teaming)

If you work with customers and you want to:
✅ qualify better
✅ avoid scope surprises
✅ speak security without overpromising
✅ deliver repeatable outcomes
