Get Back the Command I Typed A While Ago

Always we need to keep on repeating the same commands again and again. In Linux, there is a program that records each command that we type into a terminal called history. However it is understood that by typing ‘history’ over and over again each time we would like to search for the previous commands are time consuming. To get around with this, the terminal allow us to use UP arrow to get back those commands. But again, it would be taking a long time to keep searching until we are able to locate the command IF it is being typed long while ago. There are always better way, which is using CTRL+R at and empty command prompt. It should looks like this:

(reverse-i-search)`’:

By providing just partially of a previous command that we are looking for, we will find the most recent command that matches the characters AS we type them.

The other cool way is using grep command. It is relatively simple and should look something like this:

host@machine [504]$ history | grep jetty
471 jetty-dump-servlet-xss 192.168.1.10
472 less /opt/scripts/jetty-dump-servlet-xss/1/0.t
504 history | grep jetty

欧洲之王！

看看你，看看你。。。
成何体统？
都二十几岁的人了，
还蹦蹦跳跳，
而且一跳就给我跳个几分钟。

什么事那么值得兴奋啊？
看你都快合不拢嘴了！

什么？什么？
好久都没那么开心了？

也不必那么手舞足蹈地胡乱跳跃吧？

不过想想也对，
看看人家鲍比查尔顿爵士，
都七十几岁的人了，
竟都哭红满面。
想必也是开心满足干的好事吧？！

不
我想此夜站在欧洲最高荣誉领奖台上的他，
心中是在想念五十年前在慕尼黑落难的伙伴。

快乐常常以不同的方式出现，
时而跳跃，
时而哭泣！

Outrageous Inflation Rate in Zimbabwe

It is the fourth set of new banknotes to be issued by the Central Bank of Zimbabwe in 2008, and this time it is Z$500m note.

At the independence back in 1980, 1 Zimbabwe Dollar was worth more than USD1. And now, only after less than 30 years, you need to have Z$250m, then only you are able to exchange for USD1.

According to the studies, annual inflation rate in Zimbabwe is hitting 165,000% and it is being said that the prices are now double every single week.

The economy in the country is anchoring bottom in the past few years, with supplies of the likes of foodstuffs, cooking oil and petrol all running extremely low. It is believed only 1 out of 5 adults in the country are employed, with more than 3 million people have left the troubled hitting country for a better living in South Africa.

Imagine this, what if the piles of the banknote that you are holding now devalued devastatingly in the near future due to inflation, and the 1,000,000 USD saving that you have painfully saved over the past few years are only allowing you to purchase a sweet? Scary thought really.

Saving is good, but play while you can.

ASP.NET Version Leakage

There is a simple way of finding out what version of ASP.NET applications a web server is currently using. By observing the response from the target server after submitting the request to the /trace.axd or /approot/trace.axd, noted that the version is leaked in the response header:

user@machine [501]$ telnet {target} {port/normally 80 for web server}
Trying x.x.x.x…
Connected to x.x.x.x.
Escape character is ‘^]’.
HEAD /trace.axd HTTP/1.0

HTTP/1.1 403 Forbidden
Connection: close
Date: Sun, 06 Apr 2008 04:08:21 GMT
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 1.1.4322
Cache-Control: private
Content-Type: text/html; charset=utf-8
Content-Length: 2062

Connection closed by foreign host.

ps: ASP.NET provides trace functionality which aids debugging process and allows diagnostic information about a single request for an ASP.NET page to be viewed. Debug statements can be directly written in the code without having to remove them from the application when it is deployed to production servers.

你最好跑快点

每天早晨都有一只羚羊醒来,
知道一定要跑得比最快的狮子还要快,
不然就会被吃掉.

每天早晨都有一头狮子醒来,
知道一定要扑上一只羚羊,
不然就会饿死.

不论你是狮子还是羚羊,
当太阳升起时,
你最好跑快点.

‘Need For Speed’ – Shutting Down Windows Faster

At times, Windows can be reacting slow when handling hung applications and shutting down. Here are some of the tweaks, in which by modifying the value of some of the Registry Keys, it would speed up force-closing the applications and shutdown:

1. To speed up shutting down your Windows –

HKEY_CURRENT_USER/Control Panel/Desktop
double click WaitToKillAppTimeout
modify the value to something like 1000 or 2000 (measured in milliseconds)

2. To enable end running tasks automatically at shutdown –

HKEY_CURRENT_USER/Control Panel/Desktop
double click AutoEndTasks
modify the value from 0 to 1

3. To reduce the time of waiting before forcing hung applications to close -

HKEY_CURRENT_USER/Control Panel/Desktop
double click HungAppTimeout
modify the value to something like 2000

4. To speed up closing slow-ending services –

HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control
double click WaitToKillServiceTimeout
modify the value to 1000

* Getting to the Registry Editor
In Windows XP – Start > Run, type ‘regedit’, press Enter
In Windows Vista – Press the Windows key, type ‘regedit’, press Enter

** Go to HKEY_USERS/.DEFAULT/Control Panel/Desktop to change the value data of WaitToKillAppTimeout and HungAppTimeout should you would like to apply the changes to all users on the machine.

What Is lsass.exe

My firewall is always asking my permission to allow a program named as ‘lsass.exe’ to access the internet. So it has come to my concern what exactly this program is.

After some kind of research, I’ve found out that is a system process of the Windows security mechanisms called Local Security Authority Service. This program specifically handle the local security policy on the system. It is a Windows critical process that verifies users logging on to a Windows computer or server, deals with password changes, and creates access tokens. It also writes to the Windows Security Log.

An significant note about this program is it shouldn’t be terminated due to it importance for the stable and secure running of the computer.

The other issue is viral infection issue. There are some other malicious program out there named exactly or similarly to the name of lsass.exe. Under normal circumstances, the lsass.exe program should reside in the folder C:\Windows\System32. However in the other events that lsass.exe appears to be a virus, spyware, trojan or worm, most probably it will rest in the other location of your system. Take note that some viruses tend to fool people eyes by called something like ‘Isass.exe’. Lsass.exe (lsass) and Isass.exe (isass) is not the same but looks like same. They can be mixed up and confuse people. Well, the conclusion is: lsass is good, isass is bad.

As mentioned above, a completely innocent system process and a dangerous virus might come with exactly the same name. Fear not but keep your eyes open. Virus removal information can help determining whether you’re dealing with fake lsass.exe or not.

Another method of determining whether the program is a kind one, simply use Windows Explorer to check the date of the file against other files in C:\Windows\System32. If you find lots of files with the same date it usually means it’s a required Windows file.

睡不好破坏葡萄糖 充分睡眠可防糖尿病

沉睡和充分睡眠，对预防患糖尿病非常重要。

研究专家说，瘦削健康的成年男子，若连续三晚被剥夺了称为“慢波熟睡”的沉睡，会造成抗拒胰岛素情况，这种情况与患上二型糖尿病的机遇率高有关系。

研究人员说，连续三晚没睡好，其结果相当于增加体重20至30磅（9至13.6公斤）所带来的压力。这会减低人体承受葡萄糖的能力。

芝加哥大学医学院研主持这项研究工作的范科特医生指出：“这显示熟睡不但对脑部很重要，对身体其他部分也很重要。”

研究员发现，一个人只要连续三晚没睡好，身体分解葡萄糖的能力就会严重受损，患上糖尿病的几率会跟着上升。

芝大研究员指出，虽然长期面对睡眠不足的人，他们的身体处理葡萄糖的能力会相应调整，但对老人和肥胖者来说，情况可能就不一样，不良的睡眠模式可能是他们患糖尿病的因素之一。

范科特说：“我校实验室以前的研究显示，慢性或局部睡眠不足，同食欲突变、新陈代谢失常、身躯肥胖和患糖尿病的机率有许多关连。”

范科特表示，该实验结果显示，改善睡眠质量的策略，可能有助于预防或延迟人们患二型糖尿病的几率。

Think While You Sleep

Your body may be resting, but your brain’s always at work.

Studies show that people given a mathematical problem before they went to bed had higher chances of solving it the next morning. Also, if you’re studying for a test or preparing for a presentation, review the material right before you turn off the lights.

“Since most memory consolidation happens during sleep, anything you read right before bed is more likely to be encoded as long-term memory,” says Men’s Health.
