Don't lose your cool / GM's new Pontiac
|
4/17/2005

(The following are comments for NBC reality show "The Apprentice" of last week)
Chris got fired finally, after 7 weeks of continuous failure and undeniable immaturity. I couldn't believe he cried in front of the camera. He is too emotional to deal with any serious task. I saw on the news that he got himself arrested fairly recently in a restaurant due to disorderly conduct. That speaks volumes of his personality.
The other thing is GM's drive for its new Pontiac 'Solstice'. GM is hemorrhaging these days. I wish the new publicity stunt could end its losing streak. I don't want to see GM end up like Chris. By the way, 'Solstice' is cool.

He passed away quietly, but left big shoes to fill.
I did not know him personally. I never took his course. A friend of mine did, and he got a poor grade on the "Analog Circuit". I know that anything associated with "Analog" is not an easy course. I do respect his unique take on life and work. It seems finally he earned his credit in a different way. Hope his legacy could be kept.

Briefcase - CRC32
|
4/10/2005

Although the CRC32 does not have a math high ground as MD5 or PDP, it is a practically good enough solution to keep data integrity.
The most widely used CRC32 is CRC32-CCITT. There are many ways to get the it:
*) The Winzip use CRC32-CCITT to prevent data corruption. In the Menu/Options/Configuration, Click View Tab, check the check box of CRC.
*) If you happen to have installed ActivePerl on your Windows, it comes with a batch file "CRC32.bat", which does the CRC32-CCITT for file
*) However, I did not find a handy one that comes with the Cygwin or Redhat release. A close one is "checksum", which does calculate CRC32, but with a different flavor, "CRC32-POSIX.2". That is different from CRC32-CCITT
The most thorough and handy description of CRC32 I found so far is Ref[1]. In the Brief Case, getCRC32.tar.gz is provided according to Ref[1]. It simply calculates the length and CRC32-CCITT of a given file. It has been tested under Cygwin.
Goto Ref[2] to see how to download.

HAHAHAHA's Briefcase
|

I am always looking for an easy and cheap way to store and share my stuff online. In other words, some sort of free file server so that I don't have to maintain my own. I find that Yahoo will give you 30MB storage space for Yahoo Briefcase if you sign up for a free account. However, for a free account, there is a limitation that you are only able to share picture files with general public, such as .jpg files. To sidestep this limitation, I will rename all my files I want to share with the following naming convention:
{File Name}_{Real File Extension}.jpg
For example, if I want to share a file as abc.zip, I would rename it as abc_zip.jpg.
So the standard procedure to download a file from HAHAHAHA's briefcase will be
1) goto http://briefcase.yahoo.com/hahahaha_hax4
2) Click Public folder
3) Download the file you want. Say you downloaded xyz_txt.jpg
4) Change the file name according to the above naming convention. In the forementioned case, it will be xyz.txt.
4) Open the file with correspondent tools
The fileList_txt.jpg (change to fileList.txt) lists all the details for each file in the briefcase.
