出自 G.E.M. 鄧紫棋 2014 年的 喜歡你
細雨帶風濕透黃昏的街道
抹去雨水雙眼無故地仰望
望向孤單的晚燈 是那傷感的記憶再次泛起心裡無數的思念
以往片刻歡笑仍掛在臉上
願你此刻可會知 是我衷心的說聲喜歡你 那雙眼動人 笑聲更迷人
願再可 輕撫你那可愛面容 挽手說夢話
像昨天 你共我滿帶理想的我曾經多衝動
屢怨與她相愛難有自由
願你此刻可會知 是我衷心的說聲喜歡你 那雙眼動人 笑聲更迷人
願再可 輕撫你那可愛面容 挽手說夢話
像昨天 你共我每晚夜裡自我獨行
隨處蕩 多冰冷
以往為了自我掙扎
從不知 她的痛苦

I have the basic benckmarks for Raspberry Pi version 1, 2 and 3, and here is the comparison, all the benchmarks on different Pis are using the same operating system / package, so there won’t be a difference from the version of software.
The testing platform:
RASPBIAN JESSIE
Version: February 2016
Release date: 2016-02-26
Kernel version: 4.1
Since I just did these benchmarks on Raspberry Pi 3:
https://www.peterdavehello.org/2016/03/raspberry-pi-3-model-b-basic-benchmarks/
The Raspbian and all the softwares are up to date, so the benchmark results of Raspberry Pi 3 are just copied from that post, they are the same result. The results from Pi 1/2 are whole new tested, in fact they are very close to the test results I did before, I would say they are all in the tolerance scope, so I’ll just ignore the detail of the benchmarks, only focus on the final results, the performance.
PHP benchmark Script using PHP 5.6.17-0+deb8u1: (in secs, the lower the better)
Raspberry Pi model B+ – 141.145
Raspberry Pi 2 model B – 48.113, 293% faster than Pi 1
Raspberry Pi 3 model B – 26.984, 523% faster than Pi 1, 178% faster than Pi 2
PHP benchmark Script using PHP 7.0.3-5: (in secs, the lower the better)
Raspberry Pi model B+ – 48.153
Raspberry Pi 2 model B – 17.27, 279% faster than Pi 1
Raspberry Pi 3 model B – 10.239, 470% faster than Pi 1, 169% faster than Pi 2
sysbench v0.4.12 single thread: (cpu–max–prime=20000,in secs, the lower the better)
Raspberry Pi model B+ – 1332.0115
Raspberry Pi 2 model B – 765.2441, 174% faster than Pi 1
Raspberry Pi 3 model B – 478.0941, 748% faster than Pi 1, 160% faster than Pi 2
As the benchmarks I ran on Raspberry Pi B+ and Raspberry Pi 2 model B, let’s do some basic benchmarks on the latest Raspberry Pi 3.
Let’s have some photos first:
My Raspberry Pi 3 crashed during the benchmarking … so I just added a heat sink on it …
See:
@Raspberry_Pi 3 is so hot, it should have a cooler, or it may crash when running #benchmarks #RaspberryPi #pi pic.twitter.com/xTU5nvvvIF

ReactOS is a free and open source operating system for x86/AMD64 PSs, based on the best design principles found in the Windows NT architecture, development started in 1996 as Windows 95 clone project, continued as ReactOS in 1998, the goal of ReactOS is “binary compatible with Windows”, that’s awesome, the latest major release – v0.4.0 was announced last month(Feb 2016), it’s about ten years from the previous major release, okay, let’s take a look at the latest ReactOS.
The features of ReactOS:
What’s the difference between ReactOS v0.3.x and v0.4.0? The highlights from the official news – ReactOS 0.4.0 Released:
From: http://community.reactos.org/index.php/features/reactos-0-4
Looks not so cool if you compare it with some popular operating systems like Windows, FreeBSD, Mac OS X or Ubuntu GNU/Linux, but it’s a huge step of ReactOS, if you would like to take a look at it, ReactOS provides live CD iso image, you can also install it by yourself, or download pre-installed VirtualBox/VMware image, I’ll use live CD in VirtualBox virtual machine to demonstrate ReactOS as below.
ReactOS download: https://reactos.org/download / https://sourceforge.net/projects/reactos/files/latest/download
The size of zipped file(ReactOS-0.4.0-live.zip) is about 66MB, the size of the extract iso file(ReactOS-0.4.0-Live.iso) is about 198MB, compare to currently popular operating systems, it’s really tiny!
This is the first screen of ReactOS, the boot menu, there are 4 options here, but there isn’t significant difference for end-users, the most different thing may be the booting progress will be shown during the process:
Press F8 to advanced boot menu: ReactOS advanced boot menu
Booting, looks like the classic Windows XP:
Hardware detecting and installing:
Booting finished, took me only few seconds, very fast, here’s the Desktop screenshot:
My computer:
