Phonegap 編譯APK錯誤訊息

malagege published on 2014-12-15 included in Phonegap

因為phonegap build android顯示需要Android SDK 19，但是卻出現這個訊息。

The SDK Build Tools revision (19.0.3) is too low for project 'Testing'. Minimum required is 19.1.0

開起SDK Manager.exe選擇Tool資料夾裡面的Android SDK Build-tools (Rev)19.1

就解決此問題

實作異常的順力^^

import base64

fp = open("a.jpg","rb")
img = fp.read()
fp.close()

print(base64.b64encode(img))

在接下來使用requests來實作

完成:D

[Python]文件儲存unicode碼的問題

malagege published on 2014-11-19 included in Python

由於用網頁爬蟲抓取的資料存入json
文件都會顯示"{artist": "\u3058\u3093"}
但程式抓取都不會有亂碼的問題

但今天我Google大神一個整天
終於找到方法

str.encode().decode('unicode_escape')

[Python]使用requests、BeautifulSoup當網頁爬蟲

上次參加COSCUP 2014時候，電腦不只會幫你選土豆，還會幫你選新聞
最近無聊做個小實驗
使用requests、BeautifulSoup實作抓資料存成json
結果發現不會太難

html2canvas在Firefox上background-size黑畫面的問題

malagege published on 2014-11-12 included in HTML

最近使用html2canvas圖片都無法順利呈現…
最終在https://github.com/niklasvh/html2canvas/issues/288找到解決問題。
https://github.com/niklasvh/html2canvas/commit/e9afe0396019abc39bdb949d78819ae971bf5f2c

不過使用background-size: xxpx;數值仍然在Firefox上還是有問題
但是background-size:cover和background-size:contain可以順力產生圖片

Fixing “The box ‘base’ could not be found.” (Vagrant)

malagege published on 2014-10-26 included in Vagrant

vagrant box add base http://files.vagrantup.com/lucid32.box

This is an indication that the the base virtual image is not configured, usually from forgetting to finish the installation. This image is copied, and modified to produce the desired virtualized environment. It’s easy to fix, by running the following:

vagrant box add base http://files.vagrantup.com/lucid32.box

It is also possible that you installed the box under a different name (the Vagrant website sometimes refers to lucid32). Instead of downloading a new box, in this case, you can edit Vagrantfile like so, changing the box name to whatever you called it on download:
