Single-deckers on KMB 87K

A single-deck Volvo B7RLE (AVC56 RG7354) is seen KMB 87K today.

On another day, another Volvo B7RLE AVC27 (PH381) is also spotted.

How, even Scania K230UB also comes to serve 87K (ASC25 PB7069).

To find the files which appear in both file lists

This problem is always encountered in file processing, but in linux, the solution is really simple.

Firstly, sort the file lists

sort file_list_1 > sorted_list_1
sort file_list_2 > sorted_list_2

Then

comm -12 sorted_list_1 sorted_list_2


According  to the help page of comm, what the operation is doing:

Usage: comm [OPTION]... FILE1 FILE2
Compare sorted files FILE1 and FILE2 line by line.

With no options, produce three-column output.  Column one contains
lines unique to FILE1, column two contains lines unique to FILE2,
and column three contains lines common to both files.

  -1              suppress column 1 (lines unique to FILE1)
  -2              suppress column 2 (lines unique to FILE2)
  -3              suppress column 3 (lines that appear in both files)

...

Wonderful.

On running legacy audio driver (oss) on Fedora 20 (for running wavesurfer with alsa-oss)

wavesurfer  (http://www.speech.kth.se/wavesurfer/) is a popular tool for speech scientists to perform speech analysis. However, it uses the old OSS driver for sound output.

Although there is alsa-oss for compatibility, alsa-oss has been obsoleted since Fedora 20 due to no maintainer.

Therefore, in order to make wavesurfer work again, at least play sound, we need to compile alsa-oss by ourselves.

Firstly install the necessary libraries. Since wavesurfer is 32-bit software, we also install the 32-bit version of the libraries.

sudo yum install  alsa-lib-devel
sudo yum install  alsa-lib-devel.i686

sudo yum install alsa-plugin-pulseaudio.i686

sudo yum install alsa-plugin-pulseaudio

Download alsa-oss from
http://www.alsa-project.org/main/index.php/Download

and compiles

sudo ./configure
sudo make
sudo make install

And runs wavesurfer like this
aoss wavesurfer

More on electric buses in CUHK

Finally, I took photos of  all the two buses and took a ride on them. Honest speaking, in such a short ride (less than 5 minutes), it is hard to distinguish any performance difference between electric buses and conventional buses.

往太平山的途上

我來到了羅東的竹林車站，登上了往林場的火車。

那是一輛蒸汽機車，後面還有綠色的車箱。

旁邊的機車還拉著木材。

火車開動了，

經過了一片片的蔥田，

經過了一個平交道，

終於來到了天送埤站。

遙望著背後的太平山。

 車站還是六十年代的樣子，
