When you have a PC in house, you may want to know what is inside of this box. Especially it is a brand name PC.
Before I turn to Piriform Speccy, I used cpuz, everst home, etc. Now it is a new product for me. It is a free software for home user.
As Piriform said, you can see the following information:
- Processor brand and model
- Hard drive size and speed
- Amount of memory (RAM)
- Graphics card
- Operating system
XCache is a open-source opcode cacher, which means that it accelerates the performance of PHP on servers. It optimizes performance by removing the compilation time of PHP scripts by caching the compiled state of PHP scripts into the shm (RAM) and uses the compiled version straight from the RAM. This will increase the rate of page generation time by up to 5 times as it also optimizes many other aspects of php scripts and reduce serverload.
The XCache has improved my sites performance. Look at the admin page of XCache below.
The XCache Init Time is 2012-10-28 02:41:05. Until now, 2012-10-30 14:59:00, there are 373,367 hits on cache.
After I upgrade my server from php 5.2 to php 5.3.3, I need XCache to accelerate my phpBB.
I did an installation from source. Then when I run command to check php version, it shew.
I have a forum running by phpBB 3. After upgrading to phpBB 3.0.10, the board notice said, from phpBB 3.1, the next version, it will not support php5.2.
phpBB 3.1 “Ascraeus” to require PHP 5.3.2
My server is running php 5.2.17 on CentOS 5.8. To prevent the future problem I decide to upgrade php version to 5.3 now.
I followed the instruction of Chris Jean to do the upgrade. But still some issue I fixed by myself. So I put the screen shoot below for reference.
Just briefly log the steps I did.
1) Remove php 5.2
2) Install php5.3, including php53, php53-bcmath, php53-cli, php53-common, php53-devel, php53-gd, php53-ldap, php53-mbstring, php53-mysql, php53-pdo
3) Manually install php53-mcrypt module
Check PHP version.
It is the first time, I received the abuse alert form Burst.net, the VPS service provider.
They said there is some malicious content on my VPS. Their backbone providers found it and reported to them and Burst ask me to respond in 24 hours.
I click the like they provided. It is a picture. It is just an image file with jpg extension. I can open it in the browser. But I want to do even more to investigate.
So I download it and use Notepad++, which is a free open source text editor software, to open it. At the end of the file, the harmful content is shown as below:
For testing purpose, I need a CentOS 6.3. So I download CentOS DVD image. Installed it in VirtualBox as web server.
Note: The network of guest system is using bridged, which allow the guest access internet, and also allow the computer in Lan can access the guest system.
The installation is simple, no problem. I would like to share my experience I met later.
1) Prepare the network
Only lo, or loopback is active. I can not access Internet from the CentOS.
eth0 is not showing when I run ifconfig command.
We have wonderful time during past 15 years. Taking care of each other. Raising our three children. My wife, Vivian spend a lot of time with them. She is so busy. Has no time to do regular exercises. Until last month, I saw a great product, Fitbit Ultra.
It is a USB disk size device. My wife put it pocket, waist, or bra, and put on wrist when sleeping.
Fitbit Ultra can log following activities:
- Stairs Climebd
- Sleeping track
Microsoft Hotmail, or live, or outlook has the bug. It only happens when you received the email with an attachment, which has Chinese file name. And also you are using Firefox to open it.
As shown the screen shot below. the attachment has a Chinese file name with a normal extension name .pps. It is a Powerpoint file.
In Firefox, when I click to download, it pop up an download confirmation window, one underscore is added in the front, another underscore is added in the end of the file name. The extension name is changed to .pps_. Then the default program supposed to open the Powerpoint file can not open this file. I have to manually rename the file and let it run.
MovableType has a new release v5.2 on Sep. 26, 2012.
I download the full pack from the official site. Untar it and copy overwrite the old installation. Then enter the url of MovableType.

Then I sign in with the admin username.
I have three routers in house. One is provided by ISP, Telus. It is 2 in 1, including modem and router. The second router is Buffalo WZR-HP-G300NH. It is placed beside Telus device. There two are connected with lan cable. Both are in the living room ground floor. The third router is located at basement. It is Buffalo WZR0HP-G300NH2. It is connected to the second router with wireless connection as client bridged.
I drew a reference layout.
Now, let me describe the network problem. It bothered me for two months.
I have a PC, Windows 7, in the basement, connect the router 3 with wire connection.
Normally I have no problem to working on this PC. Web browsing, online gaming, streaming video.
Until last month, I tried to install a Centos server. The server can not do update, can not wget remote files.
In the server terminal window, I can ping domain and get the IP address of Google.com, but I can not traceroute path to Google.com. It said network is unreachable, something like that.
When I tracert my host from Windows, the error looks like below:
