Win10 的 Windows Update 在哪裡?

今天下午要用筆電時發覺藍芽滑鼠不動了, 我想會不會是今天有系統更新導致藍芽出問題? 但控制台怎麼找就是沒有, 奇怪 Win10 把 Windows Update 藏哪去了? 後來查網路才知道在 "電腦設定" 裡 :






點下方的 "進階設定" 可以選擇關閉自動更新, 改為手動更新 :




自動更新的好處是方便, 壞處是可能成為更新白老鼠.

完成系統更新後藍芽滑鼠還是無法連線, 我看恐怕是滑鼠本身有問題了. 還是買羅技的品質好, 我以前搭配 Inhon 筆電的 M545 現在都還很好用, 目前就暫時用這個吧 (要占用一個 USB 埠).

目前有看到下面兩個 M337 還不錯, 600 元左右 :

# Logitech 羅技 M337 藍芽滑鼠(黑色) $570
# 羅技(原廠盒裝) M337藍牙滑鼠（藍） $600

270 元買來的中國製藍芽滑鼠, 不到三個月就 GG 了.

ACER Swift 5 筆電續航力紀錄

我這台 Swift 5 筆電 (SF515-51T) 1 月底買來已近三個月, 覺得很滿意, 15.6 吋大螢幕看起來很舒服, 效能對於上網寫程式等文書作業很 OK, 最重要的是非常輕, 不到 1 公斤零負擔. 參考 :

# 購買新筆電 ACER SF515

今天開會時順便紀錄了一下電池續航力, 從 9 點離開充電器起算, 到 10 點 35 分時電量由 80% 掉到 63%, 亦即 17% 的電量撐了 95 分鐘, 所以大約 1% 可以撐 95/17=5.6 分鐘左右. 推估 80% 掉到 10% 可撐 70*5.6=391 分鐘, 約 6.5 小時左右. 若充飽至 100%, 則掉到 10 可撐 90*5.6=504 分=8.4 小時. 以上都是在開啟 WiFi 連線情況測量的.

在樹莓派上編譯執行 Java 程式

最近安裝新版樹莓派 Raspbian Stretch (2018-11-13) 後注意到 Raspbian 除了內建 Python2 與 Python3 外, 也內建了 JDK 8, 版本是 1.8.0_65 :

pi@raspberrypi:~ $ java -version   
java version "1.8.0_65"
Java(TM) SE Runtime Environment (build 1.8.0_65-b17)
Java HotSpot(TM) Client VM (build 25.65-b01, mixed mode)
pi@raspberrypi:~ $ javac -version 
javac 1.8.0_65

我自 2014 年後就沒有再碰 Java 了 (記得那年六月陪姊姊去南二中參加美術班術科考試時我正忙著測試 Java Swing 的 Data Grid 呢), 因為後來都在用 Javascript 與 Python, 五年多沒用 Java 真的變生疏了. 原本想說就此與 Java 說掰掰分道揚鑣, 但後來覺得藝不嫌多, 已經有的又何必丟掉呢?

既然樹莓派必載 Java, 那麼今天就來複習一下 Java 吧!

首先用 nano 編輯一個 HelloWorld.java 如下 :

pi@raspberrypi:~ $ nano HelloWorld.java 
pi@raspberrypi:~ $ cat HelloWorld.java 
public class HelloWorld {
  public static void main(String[] args) {
    System.out.println("Hello, world!");
    }
  }

然後馬上用 javac 編譯為 HelloWorld.class, 再用 java 執行它 :

pi@raspberrypi:~ $ javac HelloWorld.java 
pi@raspberrypi:~ $ java HelloWorld   
Hello, world! 

參考 :

# 葉難: Raspberry Pi與Java 8：Hello World

下面測試 Swing 功能, 參考之前的文章 :

# Java Swing 測試 : JOptionPane 對話框

開啟 nano 貼入範例程式 JOptionPane7.java :

pi@raspberrypi:~ $ nano JOptionPane7.java
pi@raspberrypi:~ $ cat JOptionPane7.java

樹莓派安裝 twder 套件

今天在樹莓派上嘗試安裝 Python 台銀外匯資料擷取套件 twder, 以前只在 PC 上安裝測試過, 參考 :

# Python Fintech 學習筆記 : 用 twder 模組擷取台銀外匯報價

直接用 pip3 安裝卻出現找不到相依套件 libxml2 與 libxslt 的錯誤 :

pi@raspberrypi:~ $ pip3 install twder

嗯, 大功告成!

總結以上經驗, 樹莓派安裝 twder 的程序是 :

$ sudo apt-get install libxml2-dev libxslt-dev   (相依套件)
$ pip3 install twder    (比較久)

或安裝好 libxml2 與 libxslt 後編譯 twder 原始碼 :

$ wget  https://files.pythonhosted.org/packages/d9/f6/c8c8683aa1c3599d0168bb9476d94af43f0248c0be86b53e2c796614a120/twder-0.1.4.tar.gz     (下載原始碼)
$ tar -xvf twder-0.1.4.tar.gz           (解壓縮)
$ cd twder-0.1.4                              (切換目錄)
$ sudo python3 setup.py install     (安裝)

R 語言學習筆記索引

R 語言之前是機器學習的好物, 但這兩年熱度被 Python 超越, 我對 R 的熱情似乎也冷了下來. 其實 R 是 Python 很好的兄弟, 有些用 Python 較麻煩的地方, 用 R 就很輕易解決了. 目前已整理的學習筆記如下 :

# R 語言安裝
# 在樹莓派上安裝 R 語言
# R 語言學習筆記 (一) : 基本語法與向量
# R 語言學習筆記 (二) : 矩陣
# R 語言學習筆記 (三) : 陣列
# R 語言學習筆記 (四) : 因子
# R 語言學習筆記 (六) : 串列
# R 語言學習筆記 (七) : 日期時間
# R 語言學習筆記 (八) : 函數
# R 語言學習筆記 (九) : 檔案處理
# R 語言學習筆記 (十) : 套件

Node.js 學習筆記索引

Node.js 是我非常喜歡的技術, 我原本要用它來作為樹莓派的後台, 雖然最終選擇了 Python, 但以後還是會在一台樹莓派上佈署 Node.js 的, 目前先將學習筆記做成索引如下 :

# 關於 Node.js
# 如何更新樹莓派的 Node.js
# Node.js 學習筆記 (一) : 安裝 Node.js
# Node.js 學習筆記 (二) : console 模組 (控制台) 測試
# Node.js 學習筆記 (三) : 檔案模組 fs 測試
# 樹莓派 NodeJS 升版為 11.3.0 版
# Node.js 學習筆記 (四) : http 模組測試
# Node.js 學習筆記 : 套件管理工具 npm

~ 未完 ~

樹莓派安裝 twstock 套件

今天嘗試在鄉下的樹莓派 Pi3 上安裝台股資料擷取套件 twstock, 以前只在 PC 上安裝測試過都很順利, 參考 :

# Python 學習筆記 : 台股資料擷取模組 twstock 測試 (一)
# Python 學習筆記 : 台股資料擷取模組 twstock 測試 (二)
# Python 學習筆記 : 台股資料擷取模組 twstock 測試 (三)

twstock 目前是 1.2.1 版, 我下載 ARM 版 whl 檔後放在 Dropbox 備份 :

# https://www.dropbox.com/s/6v0v5uhdv0o7u29/twstock-1.2.1-py3-none-any.whl?dl=0

安裝過程出乎意料非常順利, 只要用 pip3 安裝即可 :


1. 安裝 twstock (成功) :

pi@raspberrypi:~ $ pip3 install twstock 
Collecting twstock

Installing collected packages: chardet, urllib3, certifi, idna, requests, twstock
Successfully installed certifi-2019.3.9 chardet-3.0.4 idna-2.8 requests-2.21.0 twstock-1.2.1 urllib3-1.24.1

可見 twstock 有五個相依模組 : chardet, urllib3, certifi, idna, requests.

但匯入 twstock 卻出現錯誤 : 

pi@raspberrypi:~ $ python3   
Python 3.5.3 (default, Sep 27 2018, 17:25:39)
[GCC 6.3.0 20170516] on linux

>>> from twstock import Stock

    from .codes import codes

    from .fetch import __update_codes

    from lxml import etree

During handling of the above exception, another exception occurred:

  File "<stdin>", line 1, in <module>
  File "/home/pi/.local/lib/python3.5/site-packages/twstock/__init__.py", line 3, in <module>
    from twstock import stock
  File "/home/pi/.local/lib/python3.5/site-packages/twstock/stock.py", line 17, in <module>
    import analytics
ImportError: No module named 'analytics'

可見還缺 lxml 與 analytics 這兩個套件, 先安裝 analytics :


2. 安裝 analytics (成功) :

pi@raspberrypi:~ $ pip3 install analytics    
Collecting analytics
Collecting redis>=2.7.2 (from analytics)

Collecting nydus>=0.10.6 (from analytics)
Collecting python-dateutil==1.5 (from analytics)

Installing collected packages: redis, nydus, python-dateutil, analytics
Successfully installed analytics-0.6.5 nydus-0.11.0 python-dateutil-1.5 redis-3.2.1  

可見 analytics 又還有 4 個相依套件.


3. 用 pip3 安裝 lxml (失敗) :

接下來補安裝 lxml, 結果失敗 :

pi@raspberrypi:~ $ pip3 install lxml
Collecting lxml
  Downloading https://files.pythonhosted.org/packages/7d/29/174d70f303016c58bd790c6c86e6e86a9d18239fac314d55a9b7be501943/lxml-4.3.3.tar.gz (4.4MB)

似乎是編譯時出錯, 但密密麻麻不知從何查起. 搜尋 "raspberry pi 3 lxml" 找到下面這篇 : 


從回應中得知安裝 lxml 最簡單的方法是用下面的指令 :


3. 用 apt-get install 安裝 python3-lxml (成功) :

sudo apt-get install python3-lxml python-lxml  (其實只要 python3-lxml 即可)

Bingo! 大功告成!  不過 Yahoo 顯示成交張數是 45133, 但 twstock 抓到的是 46426821 股, 換算是 46426 張, 多了 1293 張, 這是何故?

 總結以上安裝經驗, 應該是先安裝相依套件 analytics 與 lxml, 然後再安裝 twstock, 指令如下 : 

 $ pip3 install analytics
$ sudo apt-get install python3-lxml python-lxml 
$ pip3 install twstock

AutoIt 學習筆記索引

我從 2010 年開始使用 AutoIt 幫助例行工作自動化, 也寫了一些函式庫來簡化程式碼, 更曾計畫為 AutoIt 寫一本書, 但寫了兩章就因為忙別的事停頓了. AutoIt 是我唯一使用的 PC 軟體程式語言 (.exe), 以後還會繼續整理筆記, 但排在很後面, 目前只能將已寫的筆記索引如後 :

# 403forbidden
# AutoIt 的雜湊函式庫
# AutoIt 的 FTP 功能
# AutoIt 學習筆記 : 基本語法
# 用 AutoIt 搞定煩人的連線 Timeout 問題
# AutoIt 內建 SciTE 的字型設定問題
# AutoIt 學習筆記 : 流程控制
# AutoIt 學習筆記 : 陣列

~未完~

購買 Sandisk 32GB SD 卡

中午去建國路二段 91 號 (加油站過去一點) 維碁買 2 張 Sandisk MicrSD 卡給 Pi3 用 :

# 【高雄實體店】SANDISK ULTRA Micro SDHC microsd 32G 32GB 記憶卡 TF 無轉接卡 $134

共 134*2=268 元.

露天有更便宜約 120 元的, 但加運費就要 180 元了更貴.

我誤以為 Sandisk 就是創見 (正解 : Trancend), 老闆說創見沒貨喔! 金士頓或 Sandisk 都有貨, 我說對啊就是 Sandisk! 他說差多了, Sandisk 是世界領導品牌, 攝影專業人士都指定買 Sandisk 或 Toshiba, 他說創見是入門款. 熱心的老闆還說 Sandisk 水貨很多, 他進的是有貼標籤卡片裝的公司貨, 展碁保固七年. 買個東西也長知識了.
