当 Oma 做饭的时候
2007 | Filed Under Story of Sissi | Leave a Comment
当 Oma 在厨房做饭的时候，由于油烟大，而且菜下锅的时候声音也很大， 就让 Sissi 离厨房远一些，去客厅或书房玩一会儿。于是 Sissi 就远远的跑开，双手捂住小耳朵，然后大声叫着：啪！！！啪！！！学着菜下锅时发出的啪啪声音。
今天，Oma 在厨房做饭，Sissi 在客厅独自玩耍。过了一会，Oma 没有听见 Sissi 的动静或声响，便有些担心的叫道： Sissi ，你在哪儿？ 话音才落，就听见客厅里传来 Sissi 用力的回答：哎！！！

tar command basic operations
2007 | Filed Under Ubuntu, Command, How-to, Linux | Leave a Comment
The tar (i.e., tape archive) command is used to convert a group of files into an archive (no compress).
Unlike some other archiving programs, and consistent with the Unix philosophy that each individual program should be designed to do only one thing but do it well, tar does not perform compression. However, it is very easy to compress archives created with tar by using specialized compression utilities.
The basic tar syntax is
tar option(s) archive_name file_name(s)
Remember certain option defined, c for create, z for extract and t for test. v verbose, and f is file. There are two common archive formats that people are interested in, tar.bz2 and tar.gz (tgz). tar.bz2 is more compress than tar.gz, but tar.gz is faster for creating and extracting.
Create and Compress
To create a tar.gz archive, if given list of files, use option z to indicate tar.gz:
tar czvf filename.tar.gz myfile1 myfile2 myfile3

10 flagrant grammar mistakes that make you look stupid
2007 | Filed Under English Learning | Leave a Comment
Jody Gilbert Tech Republic
These days, we tend to communicate via the keyboard as much as we do verbally. Often, we’re in a hurry, quickly dashing off emails with typos, grammatical shortcuts (I’m being kind here), and that breezy, e.e. cummings, no-caps look. It’s expected. It’s no big deal. But other times, we try to invest a little care, avoiding mistakes so that there’s no confusion about what we’re saying and so that we look professional and reasonably bright.
In general, we can slip up in a verbal conversation and get away with it. A colleague may be thinking, “Did she just say ‘irregardless’?”, but the words flow on, and our worst transgressions are carried away and with luck, forgotten.
That’s not the case with written communications. When we commit a grammatical crime in emails, discussion posts, reports, memos, and other professional documents, there’s no going back. We’ve just officially gone on record as being careless or clueless. And here’s the worst thing. It’s not necessary to be an editor or a language whiz or a spelling bee triathlete to spot such mistakes. They have a way of doing a little wiggle dance on the screen and then reaching out to grab the reader by the throat.
So here we are in the era of Word’s red-underline “wrong spelling, dumb ass” feature and Outlook’s Always Check Spelling Before Sending option, and still the mistakes proliferate. Catching typos is easy (although not everyone does it). It’s the other stuff — correctly spelled but incorrectly wielded — that sneaks through and makes us look stupid. Here’s a quick review of some of the big ones.
#1: Loose for lose
No: I always loose the product key.
Yes: I always lose the product key.
#2: It’s for its (or god forbid, its’)
No: Download the HTA, along with it’s readme file.
Yes: Download the HTA, along with its readme file.
No: The laptop is overheating and its making that funny noise again.
