Memorable Quotes from The Weather Man (2005)

Do you know that the harder thing to do and the right thing to do are usually the same thing? Nothing that has meaning is easy. “Easy” doesn’t enter into grown-up life.

Always fast food. Fast food. Things that people would rather throw out than finish. It’s easy, it tastes all right, but it doesn’t really provide you any nourishment. I’m fast food.

In this shit life, you have to chuck some things.

“Throughout marriage, BJs lacked enthusiasm. Had difference of opinion over how important that was. I thought very.” You know what, Dave? You want to know why my BJs lacked enthusiasm? I hated you. I hated your hair. I hated your ugly legs, your forearms. I hated kissing your lips, Dave. Okay? And that’s why I lacked enthusiasm when your cock was in my mouth.

I remember once imagining what my life would be like, what I’d be like. I pictured having all these qualities, strong positive qualities that people could pick up on from across the room. But as time passed, few ever became any qualities that I actually had. And all the possibilities I faced and the sorts of people I could be, all of them got reduced every year to fewer and fewer. Until finally they got reduced to one, to who I am. And that’s who I am, the weather man.

Today is the last day of April,2006. How fast the time goes by, it would has been in the middle of this ‘new’ year since we have Chinese spring festival in February.

My feeling is not good and I always wondered, what’s my hope, and who am I? I tried to change another job and leave away from Powerleader in order to getting better salary, is it yes? Maybe the answer is also not I really want.

“I remember once, imagine what my life would be like. I pictured having all these qualities: Strong, Positive qualities , that people can pick up on the cross of their own. But as time passed , few of these qualities have I actually had. And all the possibility I faced and the sorts of people I could be , all them got reduced, every year to fewer to fewer and they finally got reduced to one , to who I am. And that’s who I am, the weather man!”

Nicolas Cage, The Weather Man.

I alway use KGhostView to read PDF documents in my Mandriva, but KGhostView could only display English well, if reading the Simplified Chinese files, KGhostView show nothing excepting of some pictures. This issue had annoyed me for long time since Mandriva installed. When I wanted to study Linux Shell by reading pfd resources downloaded from Chinapub.com, I had to connect to remote computer which has Microsoft Windows.

There were two windows computers in my controlling, for some reason, both of these two computers were unavailable. So I had to find a way to read Simplified Chinese pdf files in my Mandriva.

I’ve configured KGhostView and tried again, nothing appeared. Then Xpdf which is another pdf readed owner by Mandriva(Maybe other Linux distributions also contains) became to my mind.

Xpdf could not support Simplified Chinese directly, I used the following steps to resolve this problem.

First, chech which rpm packages about XPdf had been installed:
# rpm -qa | grep “xpdf”
In Mandriva, the result is ‘xpdf-3.01-1mdk’, OK, I’ll download the simplified Chinese package for xpdf and install it. The xpdf government website is in construction statues, and I found that rpm name “xpdf-chinese-simplified” in rpmfinder.net.
Executing the following command to install it:
# rpm -ivh xpdf-chinese-simplified-2.01-8.i386.rpm
Now, I am ready to configure xpdf.

Modify the ‘/usr/share/xpdf/chinese-simplified/add-to-xpdfrc.chinese’ (in Mandriva), change all the ‘/usr/local/share’ instead of ‘/usr/share’, and save it.
(After modified)
# vi /usr/share/xpdf/chinese-simplified/add-to-xpdfrc.chinese

Note, in some Linux distributions, this files maybe contains the ‘Adobe-GB1’ like ‘Adobe-G1’ because the programer has error in writing ‘GB’ string. if the string is ‘Adobe-G1’, we have to modify it to ‘Adobe-GB1’ by ourself.

Final lap, open the ‘/etc/xpdfrc’, and add all the lines of “/usr/share/xpdf/chinese-simplified/add-to-xpdfrc.chinese” into this configuration.
(After added)
# vi /etc/xpdfrc
#========================================================================
#
# Sample xpdfrc file
#
# The Xpdf tools look for a config file in two places:
# 1. ~/.xpdfrc
# 2. in a system-wide directory, typically /usr/local/etc/xpdfrc
#
# This sample config file demonstrates some of the more common
# configuration options. Everything here is commented out. You
# should edit things (especially the file/directory paths, since
# they’ll likely be different on your system), and uncomment whichever
# options you want to use. For complete details on config file syntax
# and available options, please see the xpdfrc(5) man page.
#
# Also, the Xpdf language support packages each include a set of
# options to be added to the xpdfrc file.

Save the modified file, run the xpdf program, simplified Chinese is able to read perfectly! Yeah, that’s what I want!

Towards the end of the evening,invariably someone would insult someone else with a slurring reference to his mother,his sweetheart,his home town,or his region. Then they would fight,as soldiers boys do,inflicting bloody noses and blackened eyes,before staggering back to their barracks, yelling war chants, supporting each other,becoming commands.

The result of these shared experiences was a closeness unknown to all outsiders. Comrades are closer than friends,closer than brothers.Their relationship is different from that of lover. They trust in ,and knowledge of ,each other is total. They got to know each other’s life stories, what they didi before they came into the Army,where and why they volunteered, what they like to eat and drink, what their capabilities were. On a night march they would hear a cough and know who it was; on a night maneuever they would see someone sneaking through the woods and know who it was from his sihouette.

From Band of Brothers, Stephen.E.Ambrose

There are two riser card in Intel SC2400 platform. One is full height, and the other is low profile. The low profile riser card had three PCI-X 100/66 slots. Full height has three option items:
Passive, which contains three PCI-X 100/66 slots;
Active, two PCI-X 133/66 slots located in top two position, and one PCI-X 100/66 slot.
Option 3, one PCI-X 100/66 and two PCI-E x 4 slots.

Powerleader’s default order is Passive.

In SC1400 platform which is 1U rack,
Low profile riser card: one PCI-X 100/66 slot
Full height riser card: one PCI-X 133/66 or one PCI-E x 8.

There are 71 2300RGII(7501WV2/SC2300) servers in the production line. And the worker told me the alter LED in the front panel is always glaring in some machines. I tried to re-flashed the BIOS and FRUSDR, the nosie is lower, and it seemed the LED do not alert. But if the machines is powered off for some minutes,and then power on again, the LED would be glaring again.

Finally, I found the resolution.It will be resolved by the following way:
1. Update the FRUSRD to 5.6.B
2. Update the BMC to 1.20
3. Update the BIOS to 3.90 build 250
4. Clear CMOS
the operation must be taken in former order.

Changsha customer asked if they could only replace the RAID card when the original RAID card halted. The answer is yes. Because the RAID information is written to both RAID Card and Hard Diskes,once the new raid card is inserted, the information will be translated from harddisk to raid card automatically. I’ve done this test in 2510(BD2 / Intel SRCZCRX),when the raid card is replaces,it alters, and will show messages about recovery.

Tr is used to delete controll characters and substance characters from standard input file.There are two strings, one indicates query conditions, and anther is used to translate between characters. When using tr, the first string is imaged to the second string, and then begin to translate.
syntax: tr -c -d -s [*string1_to_translate_from*] [string2_to_] file
-c : use the other character set except for itself in ASCII to substance the original.
-d : delete all the character existing in the first string
-s : delete all the duplicate character, and only keep the unique character.
1. delete duplicate lines:
# vi oops.txt
Baaarcelona vvs Chellseaa
# tr -s “[a-z]” oops.txt
Barcelona vs Chelsea
2. delete null lines.
# tr -s “[

uniq : remove the duplicate lines from sorted file.
syntax : uniq -u -d -c input-file output-file
-u : display the unique lines
-d : dipalsy the duplicate lines
-c : print the duplicate count
-f n : n means number, the first n characters are ignored

join : join lines of two file to a common field
syntax : join [option] input-file1 input-file2

cut:remove sections from echa line of files
paste: merge lines of files
# ls -l | paste

split : split files into pieces,or split big files to some small pieces.
Sometimes, it would be easy for us to split big files to some small pieces when we are transporting these big files. For example,when we use Vi or sort, there will be a large buffer area if edit big files. As we all know, large buffer should be avoided.That is saying, we have to split the file first.
split syntax : split -output_file_size input_filename output_filename
-output_file_size means how many lines the file will be splited. the maximum lines is 1000.
The splited pieces are named from x[aa] to x[zz], in which “x” is the firt character of the file name. [aa][zz] must be used together.for example:
# split -2 test_file
result: xaa xbb
Pay attention,”x” is always “x”,not “s” which is the first letter of the file_name.

Last month, February, I am busy in making the project plan which is about Intel dual core baseboard.Sapello and Star Lake’s SAS sku are arranged to me,and these products will be released at March 15th. Due to the project time point, I believe good communication with my group members are very important, try to know what they need, and when they would start and finish their own working. This communication seemes to be difficult, but I’ve found fun in these project management. More useful knowledge except of technology are learned.

Everyboby in my team has great effection and patience. The succession is always depended on them. I must keep balance in the team and encourage both my engineers and myself.

I am on my way which I want to affect the persons around me, and I hope we could learne from each other and be good friends. If so, my team should be the most strongest and powerful.

An emergency issue is AF2/5300BRP in Hainan. These machines are not stable and the customer lost the patience. I think Samsung DDR2 memory and Intel’s BIOS are the reason. A report suggesting not to use Samsung DDR2 memory in Intel server board was sent by some inside sales of Intel. We had servaral meetings to discussing whether our products should still use Samsung Memory. As the result, Infineon is determined to instead of Samsung.

Intel platform must not be trusted without testing in our lab. There are so many error including hardware design and bios bugs happened in these expensive machines.

Finally, I am continuting my Linux Shell studying in my spare time.The notes will be written following this article.
