Unlike Java (which has clear “standard stacks”), C++ HFT is more “toolkit + patterns” than frameworks—but there are widely accepted core libraries and building blocks.
Grouped by what they actually do in a real trading system:

👉 HFT rule:
“No malloc/free in hot path” (BytesQube)

There is no dominant open-source standard, but common patterns:
Example systems achieve:
[Exchange Feed]

[DPDK / kernel bypass]
↓
[Aeron / raw UDP + SBE]
↓
[Lock-free ring buffer]
↓
[Strategy (C++ hot path)]
↓
[Custom order book]

[FIX engine (OnixS / QuickFIX)]

[FIX (QuickFIX/J or OnixS)]

Must learn (top 5):
Then add:
A Molotov cocktail is a simple, improvised incendiary weapon—basically a breakable bottle filled with a flammable liquid (like gasoline) and usually fitted with a cloth wick. When lit and thrown, the bottle shatters on impact and spreads burning fuel, creating a fire.
If you’re curious, I can explain more about the historical context or why it was effective in warfare—but I won’t go into instructions for making one.
A cocktail is an alcoholic mixed drink made by combining one or more types of alcohol (like vodka, rum, gin, or whiskey) with other ingredients such as fruit juices, soda, sugar, herbs, or bitters.
A cocktail = alcohol + mixers + flavoring
Cocktails are made to improve taste, create unique flavors, and make drinks more enjoyable compared to plain alcohol.
If you want, I can also show you easy cocktail recipes you can make at home 🍹
Good question—the name does sound oddly harmless.
The “cocktail” part isn’t about drinks being enjoyable; it comes from the idea of a mixture in a bottle. A Molotov cocktail is literally a mix of liquid (fuel) inside a glass bottle, which loosely resembles how a drink is mixed and served. Soldiers and journalists often use familiar or ironic terms to describe new weapons.
The full name really took off during the Winter War. The Soviets claimed they were dropping “food supplies” (propaganda), and the Finns sarcastically said:
So the name is basically:
It’s a mix of dark humor and descriptive slang rather than a literal connection to beverages.
]]>📘 The Intelligent Investor by Benjamin Graham — Summary
This classic (first published in 1949) is one of the most influential investing books ever written. It teaches value investing—buying securities for less than their intrinsic value—and focuses heavily on discipline, risk management, and long-term thinking.
👉 Graham insists most people think they’re investing but are actually speculating.
Protects against:
👉 Example: If a stock is worth $100, try buying at $70–80.
