LPWAN 低功率網路

這邊首先一開始先介紹 LPWAN（Low-Power Wide-Area Network，低功率廣域網路）也稱為 LPWA (Low-Power Wide-Area) 或 LPN（Low-Power Network，低功率網路），是一種用在物聯網（例如以電池為電源的感測器），可以用低比特率進行長距離通訊的無線網路。低電量需求、低比特率與使用時機可以用來區分 LPWAN 與無線廣域網路，無線廣域網路被設計來連接企業或用戶，可以傳輸更多資料但也更耗能。

IoT 語音智慧裝置

現在來談的是語音裝置，相信你會滿頭問號？語音裝置為何要談論語音裝置？因為在這個 IoT 爆炸年代 智慧家庭 中 引爆點是語音裝置！ 有可能嗎？是的讓我為你一一介紹原由。

IoT 概論

IoT 技術（英語：Internet of Things，縮寫 IoT）是網際網路、傳統電信網等資訊承載體，讓所有能行使獨立功能的普通裝置實現互聯互通的網路。更廣泛定每個物件都可以透過網路通訊傳送資料或怎與其他裝置互動。原始構想一個人周圍大約含有一千至五千個裝置。所以在換算人口數量其中預期數量會很驚人大約會有一千兆以上裝置。

制霸 IoT 30Day！ Day 01

動機

這是我第一次參加 IT 邦幫忙鐵人賽,老實說我也不知道我會不會完賽。以往經驗的要連續 30 天來產出文章來說，對於我這個文筆不好又不善於表達的人大約有 101 這樣高的障礙吧。 目前來說看到這塊領域 IoT 這邊算是百花齊放的時代，君不見台灣有專門課程或成熟的觀念來做的相關應用與學術探討。

我回來了

好幾年沒更新Blog， 這次終於花心思準備了全新使用 Hugo。


Hugo

Hugo 靜態網站產生器，哪目前其實很多種相關工具至於我為何選擇Hugo 因為他是用golang 開發的。

phalcon-devtools 增加專案樣板

之前phpconf 有會眾提到說是否自行增加樣版？基本上不會有問題而且開發團隊有增加樣版也都還沒補上．
接下來會簡單講解如何加入自行樣板．

安裝使用phalcon-devtools[

Readis

Redis is an open source, BSD licensed, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.

Using Twig with Phalcon PHP.

Twig is a modern template engine for PHP.
Now we can Using Twig with Phalcon.
How to do:
1.Install Twing in library as git submodule.

git submodule add git@github.com:fabpot/Twig.git app/library/Twig

2.Install phalcon incubator in library as git submodule.

git submodule add git@github.com:phalcon/incubator.git app/library/incubator

Libraries have been installed in:
   /Users/luosteve/tmp/cphalcon/build/64bits/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `DYLD_LIBRARY_PATH' environment variable
     during execution

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Build complete.
Don't forget to run 'make test'.
