☑️Amazon Haulの購入第一陣届きました！

▫️レビュー
・アリエクとかでよくある白いビニールに包まれてくると思ったら、ちゃんとAmazonの包装で届いた。
・アクセサリ修理部品と旅行用の小分けポーチを購入
・9/14注文→9/20到着

▫️購入一覧
・メッシュポーチ（中）約180円/個
・メッシュポーチ（小）約90円/個
・ネックレスフック20個入り約350円
・アクセサリよう修理用リング1200個入り約350円

▫️結論
100円均一・スリーコインズなどの買い物感覚で買える。ものによっては、これで全然十���。
怪しいECサイトにクレカ情報入れなくて良いのはでかい。
ただ、きっと当たり外れある商品も多くあると思う。
僕は今後も使っていくと思います😌

AI agents typically fail because the architecture is unclear, not because the model is weak.

In this handbook, Tiago teaches you how to build agents with reliable planning, memory, tool use, and bounded execution loops.

Along the way you’ll learn practical patterns for creating agents that stay stable in production.

PCB: 135 parts, 514 pads, 4 layers. I designed almost none of it.

An AI harness in VS Code calculated every part, read every datasheet, drew the schematic, checked its own work.

What would you build if the next board cost an afternoon?

Why has Frequency Modulation (FM) remained a cornerstone of radio technology for nearly a century?

While Amplitude Modulation (AM) varies the signal's strength, Frequency Modulation (FM) varies the instantaneous frequency of the carrier signal in line with the modulating audio/data signal.

Engineers favour FM across broadcasting, two-way radio, and wireless communication for several distinct advantages:

🔹 High Noise Resilience: Signal interference and atmospheric static typically manifest as amplitude variations. Because FM receivers process frequency shifts—ignoring amplitude fluctuations—they deliver significantly clearer, high-fidelity audio.

🔹 Transmitter Efficiency: FM modulation can be applied at a low-power stage. RF power amplifiers don't require high linearity to amplify FM signals, enabling the use of high-efficiency non-linear amplifiers that extend battery life in portable transceivers.

🔹 Dynamic Range Flexibility:
• Wideband FM (WBFM): Uses larger frequency deviations (e.g., ±75 kHz) for pristine sound in broadcasting.
• Narrowband FM (NBFM): Uses smaller deviations (e.g., ±3 kHz) to conserve spectrum in two-way mobile communications.

Historical Fun Fact: When pioneer Edwin Armstrong first proposed FM in the late 1920s to combat static, he went against the popular trend of narrowing bandwidth—instead choosing to expand it. His breakthrough paved the way for modern VHF broadcasting!

Lyapunov proved in 1892 that you never need to solve a differential equation to know if a system will stabilize. Find one function that behaves like energy — positive everywhere, zero at equilibrium — and if it's always decreasing, the system is guaranteed to converge. No solution required.

The trick is that real energy often fails the test. A pendulum's kinetic energy hits zero at every moment of stillness, not just at rest — so it can't prove asymptotic stability alone. You need a generalized artificial energy with cross terms mixing position and velocity. The same Lyapunov stability analysis is what ML engineers run on neural network training dynamics to prove gradient descent actually converges instead of oscillating forever on GPU clusters.
