，是总结一下申请google adsense的经验和google apps中文版下缺少的功能。网上有大量 申请 adsense 被拒 的例子，给出的理由也是千奇百怪无所不有，正是幸福都是一样的，而不幸则各有各的不同。在经历了一年又五个月收到三篇拒绝信的遭遇之后，眼看着身边的众小白都纷纷收到google寄来的支票，我们终于回归搜索 google adsense 申请 拒绝 ，imkv写的一篇blog里提到在blogger layout中的google adsense 插件。当即就收到激活信，然后是填写注册信息，收款人地址等。虽然叶子上说明是还需要两天的时间做人工review审核，但实际情况是激活后立刻就可以使用插件，并且还得到了google adsnes 的 publisher ID。在你的叶子上也可以看到google 提供的广告了～后记：
写完这篇水文的第二天下午，收到了来自Google adsense的第四封拒信。当时心情特别灰暗，在怎么形容呢，可以说是有种“天下之大，就没有我容身之地"de感觉吧。
这次是真的怒了，用学院的域名直接申请，一次通过～
不过，毕竟是学院的网站，申请到google adsense后也就一直放着，哪儿都没挂。切，谁会是冲着那几十美刀去的呢？
Then, I thought of a mind mapping software called Freemind on my Acer Note Book. Yes, it must be helpful with finding the answer!
I remembered of the bad route table after start my Ubuntu, so I run the command 'ip link set eth0 down' to mend it and 'ip r' to make sure that it worked.
yang@acer:~$ freemind
okay, it started. But I can't inert a second node after the first one 'What shall I do?'
It took me about 10 minutes to find out the reason: the Java program just stopped responding to my keyboard.
^C, freemind
Restart the program to try my luck, yet failed again.
apt-get update
apt-get upgrade
update the packages on my system to see if there is a solution. none.
search on the Internet for an alternate, failed.
Decided to write a blog to record the bad experience, and thought of the blog posting client. Tried all 3 installed on my system, and count the start time to choose the quickest, of which I can't find the name.
7:10, 1 hour had past. Quit a long time, huh? Not really, compared with the routine time I spend on PC and Internet, this time is short enough for I didn't go on searching about how to write a freemind-like software.
At last, there is still the question: WHAT SHALL I DO?
How to Get Involved in Research
It's up to you to seek out opportunities to get involved in research. How? First, excel in your courses and take time to get to know faculty (e.g., stop by their office hours to ask intelligent questions, show them interesting articles or cartoons that relate to course content).
Faculty look for students who are motivated, bright, and personable. Do well in class and be generally pleasant, and they might approach you to ask if you're interested in helping out with some research.
But don't wait to be asked to get involved in research, take the initiative. Talk with faculty and let them know that you're interested in obtaining research experience. Ask if they need any help with projects or know someone who is looking for a volunteer to assist with research. Think back to classes that you've taken. Do any professors stand out? Did any talk about the research that they conduct? Perhaps a professor in your department has published an interesting article. Remember, that although having taken a class with the professor may help to break the ice, you should also approach professors whose work interests you, regardless of whether you've taken their classes.
If you find a professor who you'd like to work with, read a couple of his or her articles. This preliminary background reading will show the professor that you're serious, interested in assisting him or her, and motivated. Send the professor your resume and a cover letter mentioning the articles you've read and why their work interests you. Express your interest in assisting them with their work and include information such as your grade point average and the courses that you've taken. Ask to set up an appointment. When you meet with the professor, express your interest, and ask whether you may assist him or her. Most professors are glad to have an extra pair of hands to work on their research projects, but sometimes professors are overwhelmed with students who wish to assist them. If the professor doesn't need additional assistance, ask if he or she knows whether other professors are looking for research assistants.
While conducting research with faculty as an undergradute is useful in enhancing your graduate school application, recognize that in most cases your work will be unpaid. What do you get in return? Experience. You'll get to see what research is all about and get a taste as to whether it's for you. Sometimes students initially have luke-warm interests in research - they get involved because it will look good on their application to graduate school, but once they see what it's like to make new discoveries, they become enthralled with the process and realize that research is fascinating.
In addition to broadening your perspective on research, you might be able to get academic credit for your work as a research assistant. If you're heavily involved in the project and it's successful, you may receive an acknowledgment in a journal article, a presentation at a professional conference, or perhaps even coauthorship on a journal article.
An added benefit of working closely with a faculty member on his or her research is that the faculty member will get to know you well and can write a letter of recommendation that describes your potential for succeeding in graduate school. By working with you over time, he or she will be able to describe your skills and strengths in a much more detailed way than if you were simply a student in class.
What If Professors Aren't Doing Interesting Research?
Remember that your research experience doesn't have to be in your area of interest. Any research experience will help. Besides, sometimes it's good to get involved in different areas of research because you may discover new interests. As an undergraduate, a variety of broad experiences that provide you with a taste of several research areas is better than conducting research only in your area of interest. Of course, if you're completely disinterested in the research topic it might be difficult to remain motivated and do a good job. Understand your interest level and limits when deciding whether to assist a faculty member with his or her research because poor or inconsistent work will not be helpful and can hurt your chances for a persuasive letter of recommendation that benefits your application to graduate school. Regardless of the research topic, many of the tasks that research assistants complete can be tedious: copying, sharpening pencils, administering surveys, entering data into SPSS, and so on. Sure, some of these tasks are boring, but they're necessary for completing the research project.
Be a Responsible Research Assistant
If you get involved in research remember that the faculty member is depending on you. He or she can't afford to have assistants who are unreliable or careless. Agreeing to assist a faculty member with his or her research is a big commitment that you shouldn't take lightly. Your research tasks should come first - treat the research project as a class and be diligent. There's nothing worse than a student who is enthusiastic at first but disappears or performs inconsistent and careless work. The research project gets disrupted, tasks often must be completed again, and the faculty member loses faith in the student. If you find yourself in such a situation, you won't be able to ask the faculty member for a letter of recommendation. Also understand that faculty talk - other professors may learn about the quality of your work which can influence your interactions with them as well. In other words, if you're going to assist a professor with his or her research, be responsible or you may not like the consequences.

The saved sessions are (by default) in "/var/tmp/vi.recover".
If you don't need to recover the sessions, clean the directory out.

This patch attempts to address this weakness by inserting an informational header to messages sent from PHP via the mail() function. The header identifies both the script and the apparent IP address that called it.
The header added has the form:
X-PHP-Script:for
Run in single user mode.
Put the /usr/src and /usr/obj directories on separate file systems held on separate disks. If possible, put these disks on separate disk controllers.
Better still, put these file systems across multiple disks using the ccd(4) (concatenated disk driver) device.
Turn off profiling (set “NO_PROFILE=true” in /etc/make.conf). You almost certainly do not need it.
Also in /etc/make.conf, set CFLAGS to something like -O -pipe. The optimization -O2 is much slower, and the optimization difference between -O and -O2 is normally negligible. -pipe lets the compiler use pipes rather than temporary files for communication, which saves disk access (at the expense of memory).
Pass the -jn option to make(1) to run multiple processes in parallel. This usually helps regardless of whether you have a single or a multi processor machine.
The file system holding /usr/src can be mounted (or remounted) with the noatime option. This prevents the file system from recording the file access time. You probably do not need this information anyway.
# mount -u -o noatime /usr/src
Warning: The example assumes /usr/src is on its own file system. If it is not (if it is a part of /usr for example) then you will need to use that file system mount point, and not /usr/src.
The file system holding /usr/obj can be mounted (or remounted) with the async option. This causes disk writes to happen asynchronously. In other words, the write completes immediately, and the data is written to the disk a few seconds later. This allows writes to be clustered together, and can be a dramatic performance boost.
Warning: Keep in mind that this option makes your file system more fragile. With this option there is an increased chance that, should power fail, the file system will be in an unrecoverable state when the machine restarts.
If /usr/obj is the only thing on this file system then it is not a problem. If you have other, valuable data on the same file system then ensure your backups are fresh before you enable this option.
# mount -u -o async /usr/obj
Warning: As above, if /usr/obj is not on its own file system, replace it in the example with the name of the appropriate mount point.

Sorry, i forgot to send my conf...
The build error was my mistake, i forgot that sctp needs INET6, even if you
dont will use V6...
My apologize :)

也许有一天，他再从海上蓬蓬的雨点中升起，
飞向西来，再形成一道江流，再冲倒两旁的石壁，
再来寻夹岸的桃花。然而，我不敢说来生，也不敢信来生......
我爱你/可是我不敢说/我怕说了/我马上就会死去/
我不怕死/我怕我死了/再没有人像我一样爱你
－－－－－－－
我爱你！可是我不敢说
我爱你，可是我不敢说出口
因为你在我心里是那样的纯洁而完美
我爱你，可是我不敢说出口
我怕说了，
你会马上在我的世界里消失
因为你我相距千里
我没有握住你双手的机会
我爱你，可是我不敢说出口
因为我除了真心的爱和我的全部幸福给你
我，什么也不能保证
我爱你，可是我不敢说出口
我怕说了，
我会死去

我怕我死了
在这个世界上再也没有人像我一样爱你
也许我就该这样静静的等待

我怕在等待的分分秒秒中你正受着煎熬
正在煎熬着人世间的冷暖、忧愁
我爱你，可是我不敢说出口

The test builtin command returns 0 (True) or 1 (False), depending on the evaluation of an expression, expr. You can also use square brackets: test expr and [ expr ] are equivalent. You can examine the return value by displaying $?; you can use the return value with && and ||; or you can test it using the various conditional constructs that are covered later in this tip.
|
In the first example in Listing 1, the -gt operator performs an arithmetic comparison between two literal values. In the second example, the alternate [ ] form compares two strings for inequality. In the final example, the value of the HOME variable is tested to see if it is a directory using the -d unary operator.
You can compare arithmetic values using one of -eq, -ne, -lt, -le, -gt, or -ge, meaning equal, not equal, less than, less than or equal, greater than, and greater than or equal, respectively.
You can compare strings for equality, inequality, or whether the first string sorts before or after the second one using the operators =, !=, <, and >, respectively. The unary operator -z tests for a null string, while -n or no operator at all returns True if a string is not empty.
Note: the < and > operators are also used by the shell for redirection, so you must escape them using \< or \>. Listing 2 shows more examples of string tests. Check that they are as you expect.
|
Some of the more common file tests are shown in Table 1. The result is True if the file tested is a file that exists and that has the specified characteristic.
| Operator | Characteristic |
|---|---|
| -d | Directory |
| -e | Exists (also -a) |
| -f | Regular file |
| -h | Symbolic link (also -L) |
| -p | Named pipe |
| -r | Readable by you |
| -s | Not empty |
| -S | Socket |
| -w | Writable by you |
| -N | Has been modified since last being read |
In addition to the unary tests above, you can compare two files with the binary operators shown in Table 2.
| Operator | True if |
|---|---|
| -nt | Test if file1 is newer than file 2. The modification date is used for this and the next comparison. |
| -ot | Test if file1 is older than file 2. |
| -ef | Test if file1 is a hard link to file2. |
ipv4_addrs_vr0="192.168.0.1/24 192.168.1.1-5/28" #I prefer this way
It is also possible to add IP alias entries using ifconfig(8) syntax. Assuming that the interface in question was ed0, it might look something like this:
ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"
ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"
Make sure the host's names (including localhost) are defined in
/etc/hosts, and that /etc/hosts is being used in name resolution
(on 5.3 that would be configuration via nsswitch.conf(5)).
I solved the problem by adding back my ppp ip address into my hosts file.
There is no lookup for your IP address into a hostname. If you have
multiple interfaces or multiple addresses on one interface then you
must have a lookup for all the IP addresses.
The message there isn't an error - it's a warning. Just an annoying one :-)

Your system can't find all names for all interfaces.
Check for funny addresses with "ifconfig -a"

Good call, but unfortunately, this is not very good in performance either..
If you use latest kernel, your ipfw2 should have the lookup tables patch which
uses radix lookup. { blah or bleh or x or y or z } list is a linear lookup,
causing the system to lookup twice in linear fassion to come to a match. It is
not exactly any better in terms of performance efficiency than adding hundreds
of straight ipfw rules each with a ip address specification.
Try this if you have tables feature:
ipfw table 1 add x.x.x.x/32
ipfw table 1 add x.x.x.x/32
ipfw table 1 add x.x.x.x/32
ipfw table 1 add x.x.x.x/32
ipfw table 1 add x.x.x.x/32
ipfw table 1 add x.x.x.x/32
ipfw table 1 add x.x.x.x/32
ipfw table 1 add x.x.x.x/32
ipfw table 1 add x.x.x.x/32
ipfw table 1 add x.x.x.x/32
ipfw table 1 add x.x.x.x/32
ipfw add 300 deny ip from table(1) to any
No matter how many elements you got in table 1, due to radix/patricia trie
lookup as with kernel routing table, the time spent in looking thru firewall
elements is O(32) constant.
To demonstrate the efficiency:
Test #1: Start with 1 ipfw rule (the last rule 65535 being allow all) that
denies one ip address on the DUT. Flood the remote tester device that is not
denied by the ipfw rule. Start the test, and increment the ipfw rules from 1
to 10. Result:
1 rule: 140kpps
2 rule: 140kpps
3 rule: 138kpps
4 rule: 137kpps
5 rule: 135kpps
6 rule: 135kpps
7 rule: 132kpps
8 rule: 133kpps
9 rule: 131kpps
10 rule: 129kpps
Test #2: Perform the exact same test above, however use a lookup table to store
the elements from 1 to 10:
1 element in table: 140kpps
2 element in table: 140kpps
3 element in table: 140kpps
4 element in table: 141kpps
5 element in table: 140kpps
6 element in table: 139kpps
7 element in table: 140kpps
8 element in table: 142kpps
9 element in table: 140kpps
10 element in table: 140kpps
