I am pleasantly surprised that Google Drive has increased her free storage from 5GB to 15GB. Maybe it is due to competition – Other cloud storage providers are offering bigger storage than 5GB. I personally won’t leave Google Drive even she did not increase the capacity.
So, no need to delete files when your storage is getting near to 5GB, but it is still a good practice to keep useless files cleaned all the time, no matter how big storage you have.
今天再次惊讶于 Google 的强大。
在 Google Drive 里打开一个 PDF 文件，是一个类似于 lightbox 效果的在线预览。我今天打开的是一份英文文档扫描后保存为 PDF 的文件，lightbox 里出现的是图像。神奇的是，用鼠标去选中其中某些文字，也能像操作文本文件一样高亮显示选中的部分；更神奇的是，按下 Ctrl+C，再到别处 Ctrl+V，粘贴出来的 OCR 以后的文字。
PDF 在线预览、图形类似文本的高亮显示、OCR，这三件事情能如此完美的结合在一起，不简单。
老爸最近爱上钢琴。
他问我：“能不能打印几张空白钢琴谱给我？”
我答：“没问题。”
他又问：“不用我发链接给你吧？网上到处都是。”
我说：“不用。既然到处都是，那我肯定找得到。“
于是我就搜索”空白钢琴谱“，”空白钢琴谱 filetype:pdf“，”空白钢琴谱 filetype:doc“，”空白钢琴谱 filetype:docx“，确实很多地方都有，可是都要注册后才能下载，哪怕是免费，我恨注册。就这样找了一圈，还没下载到一个。
被逼得没办法了，还是不想注册。然后想到，中国的网站就爱让人注册，咱可以找国外的嘛！上 Google Translate，钢琴谱叫 piano sheet music，那就搜”blank piano sheet music filetype:pdf”，一找一个准。
真是强烈的对比。“自由、分享”，咱中国人热切盼望的，轮到自己能控制“自由、分享”时，自己又在想什么？
以后不要找了，看这里，免费、免注册下载空白钢琴谱。
安兔兔定量分析一个手机的好差，我很喜欢。连测了几个时下和过时的 Android 设备，给我了一个硬件在几年内进步的曲线。
我又突然想到 Apple 产品所采用的硬件都严重不匹配它的高价，就想安兔兔是不是已有一个 AnTuTu for iPhone 来量化对比一下 iPhone 到底有多少物不符所值。调查了一下，遗憾！AnTuTu 没有 iPhone 版，可能怕对果粉心理打击太大吧。我发现一个有趣的现象，果粉谈到 AnTuTu，不是说没听说（是真不知道还是掩耳盗铃？），就是说 iPhone 不需要 AnTuTu。
iPhone 虽没有不同硬件厂家的横向对比，但纵向对比 iPhone 4, iPhone 5 也可以看看 iPhone 进步了多少。可是果粉们视 iPhone 如同洪水猛兽，归根到底是害怕看到 iPhone 和 Android 手机、iPad 和 Android 平板设备对比后惨不忍睹的分数。因为害怕，所以果粉们说分数有意思吗？————看优劣得看流畅性、整合度。流畅性和整合度没有客观指标，于是各种争论可以变成了浑水。我想提请果粉注意的是，Android 设备来自众多厂商，硬件参差不齐，我在一台价值 £40 的 Storage Options Scroll 平板上跑一个写汉字软件，确实不流畅，可这个软件跑在 Samsung S3 手机上就非常流畅。如果真要对比流畅性和整合度，就对比一下时下同等价格的 iPhone 和 Android 手机对比，果粉们有这个自信吗？
今天我在 Google spreadsheet 操作时发生一件奇怪的事情，让我对 Google spreadsheet 的安全性产生了怀疑。
我选中了最后一行的两个单元格，“70”和“否”两格，按住了 Ctrl 键，鼠标指向右下角，然后向下拖曳了三格，原想是复制三行“70”和“否”两格。结果出现了如图所示的结果。重试了几次，仍是这样的结果。非常奇怪！是不是复制了别人某个单元格里的内容？
后来我发现，要复制“70”和“否”两格，不用按住 Ctrl 键，直接拖曳就好了。
按住了 Ctrl 键，出现的文字是从哪里来的？谁能告诉我？
Do you know G+ page is a “person”?
I mean, as you have a Google account, and fill in G+ profile, you are a G+ person. You start building your cycles, adding people you know (or even don’t know), and posting to individuals, cycles, or Public.
You can also create one or more G+ pages. What is G+ page? It has confused me for long. Now I know, it is a kind of G+ person, same as you. It was the terminology “Follow” confused me.
I only find “Follow” on G+ pages. However, “Follow” basically is adding this G+ page to your cycle(s), same as adding some real person. G+ page can also add you to its cycle(s), or not to add you, same as a real person makes such a choice. Even G+ page does not add you, you can still see all its Public posts in your cycle stream, seem as you add President but President does not add you.
A real person can add another real person or a G+ page to his cycle(s). A G+ page can also add another G+ page or a real person to its cycle(s). This conforms to G+ page is a person.
Since a real person can create as many G+ pages as he like, and G+ pages can add each other, which make things worse. I mean, a messy social network sharing loads of rubbish.
Nevertheless, I can not change the world. A network full of rubbish is not something I should worry too much about. What I can do is not to produce rubbish.
I hope this post is not regarded as a kind of rubbish.
