基於 Least Squares 室內定位方法 « KitSprout
室內定位是我的碩士研究題目，目前主要是使用藍牙 4.0（Bluetooth Low Energy, BLE）裝置抓取接收的訊號強度來實現室內定位的功能，為什麼我會選擇 BLE 而不使用 Zigbee 是或 WI-FI 呢？其實在工業上因為 Zigbee 的組網能力具有很大的優勢，這點是 BLE 無法比較的，但 Bluetooth 在民間普及程度遠高於 Zigbee（從 Nokia 時代手機上就有 Bluetooth 了），功耗上也遠低於 WI-FI，加上 Nrdic nRF51 系列的出現，因採用 ARM CrtexM0，支援已經習慣的 Keil MDK 開發環境，所以就果斷選擇藍牙陣營了，相信在 BLE 之後，藍牙仍會不斷的壯大阿。 Indoor positioning.

Choosing an HTTP Status Code — Stop Making It Hard | Racksburg
What complicates matters is that the official HTTP/1.1 guidelines — the RFC — was originally written in 1997.† That’s the year you went surfing the cyberweb in Netscape Navigator on your 33.6kbps modem. It’s a little like trying to apply Sun Tzu’s Art of War to modern business strategy. Timeless advice, to be sure, but […]
