The relationships among common probability distributions through limits, special cases, and transformations.

Examples include the binomial approaching the normal as n → ∞ (μ = np, σ² = np(1 − p)), Poisson as the limit of binomial (λ = np, n → ∞), exponential as gamma(r = 1), uniform as beta(α = 1, β = 1), and Cauchy as t(ν = 1).

These insights guide statisticians in choosing appropriate models and approximations for data analysis in finance, epidemiology, and engineering.

To carve circuits a few atoms wide, EUV lithography bounces 13.5nm light off mirrors so perfect that if you scaled one up to the size of Germany, the tallest bump would be under a millimeter.

@Plinz This is retarded and dishonest.

I would love to post all my custom hacking tools for clout but that's like the worst op sec imaginable. Also I know nothing about hacking. What's an IP?

@RhysSullivan I didn't want to say it but ..

[Rhys @RhysSullivan]

tbh i never really cared about the agents​.md vs claude​.md stuff because you can just do

ln -s agents.md claude​.md

and move on with your life

[Charles @unsignedbytes]

@vslashwr Lost potential. Harness it.

They just can't get jobs 😂😂😂😂

Some of the smartest ppl have no degrees

They are self taught

I need to get back to game dev but I'm just prepping for the fall.

What is an IGBT & why is it an Electronics Powerhouse

Have you ever wondered how we efficiently manage high power in everything from electric vehicles to renewable energy systems? The IGBT (Insulated Gate Bipolar Transistor) is one solution.

As electronics engineers, we often face a trade-off between the fast switching of MOSFETs and the high-voltage capability of BJTs.

The IGBT was designed to solve this exact dilemma by merging the best features of both technologies into a single semiconductor device.

Key Highlights of the IGBT:
🔹 Hybrid Performance: It features the high input impedance and fast switching of a MOSFET, combined with the low saturation voltage and high current handling of a Bipolar Transistor.
🔹 Voltage Controlled: Like a MOSFET, it’s easy to drive—requiring only a small voltage at the gate to switch high current levels.
🔹 Efficiency: With a very low ON-resistance, it minimizes power dissipation, making it ideal for high-power applications.

Where do we see them in action?
• Motor Control & Traction: Powering the drive systems in EVs and trains.
• Renewable Energy: Converting DC power from solar panels into AC for the grid.
• SMPS & Inverters: Providing the heart of efficient power supplies and industrial inverters.
• Inductive Loads: Handling the heavy lifting in industrial machinery.

While they may not be as fast as pure MOSFETs at lower power, their ability to handle thousands of volts and hundreds of amps makes them indispensable in the push for a more electrified and sustainable future.

Lami's Theorem ✍️

It explains how three forces pull on a single point from different directions, keeping everything balanced and still. The main idea is straightforward. The strength of each force depends on the angle it has. If a force faces a wide angle, it must be strong. If the angle is narrow, the force can be weaker. The forces adjust to maintain balance. Imagine a lamp hanging from two chains attached to a ceiling. Gravity pulls the lamp straight down, while the two chains pull it up at angles. None of the forces wins; they balance each other perfectly. Lami's Theorem shows how the strength of each of these three forces relates to the angles between them. A critical condition is that there must be exactly three forces, all meeting at one point, and the object must not be moving. When these conditions hold true, the forces and angles follow a clear pattern. Knowing just the angles is enough to determine any unknown force.
