Files with spaces on its name are a bad thing, they will not work correctly with some Linux commands and will test your patience.
Fortunately there is a simple command to remove it:
$ find . -depth -name "* *" -execdir rename 's/ /_/g' "{}" \;

I was looking for a way to converting audio (WAV file) to MIDI files then I discovered the “waon” project:
http://sourceforge.net/projects/waon/
Using it I can convert wave files to mid files. First I convert MP3 to wav files this way:
$ mpg123 -w file.wav file_original.mp3
Then finally I convert the wav to mid using this command:
$ ./waon -i file.wav -n 2048 -b 60 -t 120 -o file.mid
After converting many music files to mid I decided to convert an audio voice (postcast) and try to understand it (I suggest you to start with a slow audio like these at http://learningenglish.voanews.com).
Initially you cannot understand nothing, but after few minutes your brain adapts to it and will understand everything.
Now see the postcast file size comparison:
$ ls -l file.wav -rw-r--r-- 1 alan alan 228920876 Feb 28 13:06 file.wav $ ls -l file.mp3 -rw-r--r-- 1 alan alan 20764946 Feb 26 15:59 file.mp3 $ ls -l file.mid -rw------- 1 alan alan 580111 Feb 28 13:08 file.mid

I bought an IP Camera (to use inside a product we are developing) similar to this one:
http://www.alibaba.com/product-detail/H-264-960H-the-smallest-38x38mm_1389016530.html
Unfortunately it arrived with no documentation. Even the IP I should figure out myself, it was not a big issue because normally IP Cameras use the 192.168.1.x range.
Using the ping command it was easy to figure out it was in the address 192.168.1.168.
Now let me see which ports are opened:
$ sudo nmap -sS -P0 192.168.1.168 Starting Nmap 6.47 ( http://nmap.org ) at 2015-02-08 20:47 EST Nmap scan report for 192.168.1.168 Host is up (0.099s latency). Not shown: 996 closed ports PORT STATE SERVICE 23/tcp open telnet 80/tcp open http 3001/tcp open nessus 8080/tcp open http-proxy MAC Address: 00:A7:21:63:A7:7F (Unknown) Nmap done: 1 IP address (1 host up) scanned in 27.41 seconds
Wow, telnet port is open, let try it:
$ telnet 192.168.1.168 Trying 192.168.1.168... Connected to 192.168.1.168. Escape character is '^]'. A320D login: root Welcome!Baby! [~]#
CRAZY!!! It allows me to log in as root with not password and printed a funny “Welcome!Baby!” msg!
Well, it is funny to me, but for people using these cameras connected to Internet to protect their property it is very dangerous.
UPDATE: More info about the camera hw/processor:

UPDATE 2: I didn’t find a serial connector in the board, then I searched in the datasheet and discovered UART1 RX is pin 87 and TX is pin 88. Then I connected a small wire from my USB/serial dongle to pins 87 and 88, then after testing many serial configuration I discovered that they are using an unusual baudrate 38400 8n1 and finally got the boot log:

Está dica é muito antiga e só estou postando aqui porque frequentemente recebo emails pedindo instruções de como compilar.
Infelizmente você precisará de uma versão de Linux antigo, i.e. Debian Potato, pois o Festival + software OGI precisam ser corrigidos p/ funcionar com uma versão diferente do GCC 2.95.
Instruções para instalar o diphone em Portugues para o Festival
PASSO 1 – DOWNLOAD
Baixe os seguintes arquivos do site do Festival e do OGI:
*festival-1.4.1.tar.gz
*speech_tools-1.2.1.tar.gz
*festlex_OALD.tar.gz
*festlex_POSLEX.tar.gz
*festvox_rablpc16k.tar.gz
*OGIresLPC-2.0.7.tar.gz
Consiga com o arquivo que adiciona suporte ao portugues do Brasil:
*festival_portuguese.tar.gz
PASSO 2 – DESCOMPACTAÇÃO
Crie um diretório para instalar o Festival(ex. /TTS)
Extrai todos os arquivos acima para o diretório que você criou.
PASSO 3 – CONFIGURAÇÃO
Renomei o arquivo /TTS/speech_tools/config/config-dist para:
/TTS/speech_tools/config/config
Renomei o arquivo /TTS/festival/config/config-dist para:
/TTS/festival/config/config, vá até as ultimas linhas deste
arquivo e inclua as seguintes linhas:
ALSO_INCLUDE += OGIcommon
ALSO_INCLUDE += OGIdbase
ALSO_INCLUDE += OGIresLPC
ALSO_INCLUDE += OGIinsert
PASSO 4 – INSTALAÇÃO
Entre no diretório /TTS/speech_tools e execute o comando “make”, agrade o
termino da instalação, ok, deu certo!!!?
Em seguida vá para /TTS/festival e execute o comando “make” novamente, agrade
o termino da instalação, pronto, Festival instalado com sucesso!
PASSO 5 – EXECUTANDO
Entre no diretório /TTS/festival/bin e execute o comando “./festival”.
Aparecerá o prompt , então digite: “(voice_aga_diphone)”
Pronto agora é digitar: (SayText “Obrigado Mauricio!”)
Alan Carvalho de Assis
P.S. – Quando eu tentei instalar a primeira vez, ocorreu um erro, mas foi
porque eu tentei compilar /TTS/festival antes de ter compilado /TTS/speech_tools
This is the way I’m flashing NuttX on my board (called “GreenBone”) using the current (as of 20150129) OpenOCD:
This is my openocd.cfg :

Then I execute OpenOCD this way:
$ sudo openocd -f openocd.cfg Open On-Chip Debugger 0.9.0-dev-00251-g1fa4c72 (2015-01-28-20:08) Licensed under GNU GPL v2 For bug reports, read http://openocd.sourceforge.net/doc/doxygen/bugs.html Info : The selected transport took over low-level target control.

Finally I connect to its telnet server and flash nuttx.bin:
