Backblaze, a nice backup tool

53 sec read

I purchased at least 2 portable hard drives and many USB drives to backup important files. For a while I did my backup every day by copying files to the portable hard drives. But then I get lazy and stopped doing this. The last time I backup was probably a year ago. My portable drive is covered by dust. I always have this fear in the background: what if my computer collapse?

By chance I ran into backblaze and immediately love it. It simply backup all your computer (except operation system and application files) silently in the background all the time. After the initial installation, you don’t have to do anything. Great!

Is it similar to Dropbox? I am also a user of dropbox. No, they are different. The main purpose of dropbox is to make file synchronization over multiple computers easy. And yes you have to put your files in dropbox’s folder. Backblaze backs up all your files. Then when bad things happen you can retrieve your file thru web (or you can request them to send you the files via mail). The backed up files are not meant to be retrieved frequently.

You can check Backblaze out at http://www.backblaze.com

[update 2013/8/19] After using Backblaze for a while, I think there are two issues Backblaze have:

  1. Sometimes it takes a lot of CPU
  2. After a external hard disc is backedup, you have to connect the hard disc at least once a month otherwise Backblaze will delete your backups.

一盘围棋,一开始他吃了我一条龙,领先80目,后来我竟然翻盘了

断断续续下围棋已经很多年了。小学的时候就开始接触,也没人教,全自学。水平业余低级水平,在OGS上是4级。下围棋纯属休闲娱乐。赢了很高兴,输了有时候气得我把鼠标都拍坏了。下围棋确实很耽误时间,一盘至少半个小时一个小时的,因此很长一段也没下了。最近和好友尚伟峰在OGS上下了几盘,我就又棋瘾上来了。今天下了三盘,录了下来,算是个记录吧。 第一盘的对手是人,水平和我一样,4级。一开始他吃了我一条龙,领先80目,后来我竟然翻盘了。中间两个人多次都出现失误,他的一块棋是死期我竟然看不见。不管怎样,快结束时把他的角杀了,他就投子认输了。视频如下(在youtube): 第二、三盘的对手是人工智能,水平比我高到天上去了。我就厚脸皮选择被让11个子。如果系统允许让18子我肯定会选择18子的。和人工智能下棋,我的策略就是忍辱负重,保证棋是活的,不能一块棋一不小心被吃。如果一条大龙被吃,就完了。我发现OGS上的人工智能下围棋有下面的特点: 东一榔头西一棒槌(频繁脱先)。你跟着他走一会儿都晕了 对中腹把握能力强。一不小心就被它围出个大肚皮 杀伤力强。如果不在意,可能一条大龙就被杀了 落子速度快,一秒钟就落一个子。这么快的落子我就不由自主也下得快,失误就多。 第二盘棋我不小心一块棋就死了,不过还好,其它地方损失不大,因此赢了。第三盘也赢了。下面是视频 (在youtube):

人工智能已经强大到能写论文了?

作为科研人员,我们都有个梦想,如果有一天AI可以帮我写论文就太好了!这听上去好像是遥远的科幻,不过,当我使用了文献鸟Stork的新高级功能“人工智能创意论文摘要”后,我觉得,这一天马上就要来了。 为了看看人工智能有多厉害,我随便想了个有意思的主题,就是人和宠物狗之间的欺骗行为的大脑机制。这是一个还没有被研究的课题,到现在为止还没有人同时测量过一个人和他的宠物狗的大脑,当然也没有文章发表。我有这个想法已经有一段时间,但还是个模糊的想法,具体怎么实现以及结果怎样我也不知道。于是,我看看人工智能会写出什么。于是我输入了: Deception between human and pet dog, an fNIRS hyperscanning study 点击“开始”按钮后,人工智能好像想了几秒钟,然后文字便源源不断地出现了。 The present study aimed to investigate the neural correlates of deception...
