cdnjs git repositories visualization using gource

Gource is a famous version control visualization tool, supports git, svn, hgbzr and cvs2cl, I tried to use gource to visualize the CDNJS development history, and here are the videos I uploaded to youtube.

Raspberry Pi (1) Model B+ basic benchmarks

hmmmm … I’ve made some simple and basic benchmarks on Roseapple Pi and Raspberry Pi 2, so here come the very late benchmarks(HardinfosysbenchPHP benchmark Script) on the first generation Raspberry Pi. Actually, I bought the Raspberry Pi Model B very early, and the experience about the performance of it is not so good, to do some benchmarks is just for understanding the performance difference.

I’m using Model B+ here, which has the same chip Broadcom BCM2835 as Model be does, although it has larger main memory than Model A+, due to the benchmarks are very simple, and focus on CPU, so I don’t expect a notable performance difference between model A+ and B+(or model B).

In this post, the platform is Raspberry Pi (1st gen) model B+ using Raspbian Jessie.

The info of the Raspbian image I used:

Version: February 2016
Release date: 2016-02-09
Kernel version: 4.1

Here are the test results:

Raspberry Pi 2 model B basic benchmarks

Just want to compare Raspberry Pi 2’s performance with Roseapple Pi’s, not only which one is faster, but also how faster, so I just did the same basic benchmarks on Raspberry Pi 2, and maybe will also do the same benchmarks (Hardinfo 、sysbench、PHP benchmark Script) on the 1st generation of Raspberry Pi.

Roseapple Pi benchmark:

https://www.peterdavehello.org/2016/02/roseapple-pi-%e8%93%ae%e9%9c%a7%e6%b4%be-%e6%95%88%e8%83%bd%e7%b0%a1%e6%b8%ac-benchmark/

The platform is Raspberry Pi 2 model B using Raspbian Jessie, no Android this time.
Full desktop image based on Debian Jessie

Version: February 2016
