Quem é o verdadeiro animal?

O animal era um dos personagens mais queridos do campus da UFRGS

No colo do médico e professor de genética Renato Zamora Flores, um cão vira-lata ajudava dezenas de crianças a superarem o trauma da violência. Fascinadas pelo animal, usado em um programa de extensão da Universidade Federal do Rio Grande do Sul (UFRGS) para ajudar na terapia, elas não viam a hora de reencontrá-lo nas consultas. No sábado, o cachorro foi morto, aparentemente, com uma paulada no Campus do Vale, no bairro Agronomia, na Capital.

– Ele era tão querido que o treinei para ajudar na terapia das crianças, uma técnica muito usada pela capacidade dos animais cativarem os pequenos. Elas não contavam o problema para mim, mas para o doutor Alegria. E ele ficava quietinho no meu colo, ouvindo por mais de uma hora – lembra Flores, o primeiro a receber a notícia.

Adotado há cerca de três anos, o animal era um dos personagens mais queridos do campus. Além de auxiliar os atendimentos do Projeto Proteger – Saúde e Comportamento Violento, era parceiro durante as aulas. Alegria acompanhava o professor e, segundo ele, conquistava as alunas. Era comum o cachorro terminar as aulas no colo de alguma moça, ganhando fama de paquerador.

Funcionários suspeitam que cães estão sendo exterminados

A maior parte do dia, Alegria ficava na sala do professor. À noite, eventualmente, dormia na rua. No começo da noite de sábado, um segurança da universidade ligou para ele dizendo que o cão havia morrido. Ao voltar ao campus, o professor encontrou o cachorro com a marca de um golpe na cabeça. Com isso, tornou-se o 10º animal morto no campus em dois meses, indicando a possibilidade de um ou mais exterminadores de cães.

Os casos foram registrados na 15ª Delegacia da Polícia Civil, que encaminhou o caso para a Polícia Federal por se tratar de uma área da UFRGS.

– Estamos preocupados com isso. Sempre existiram animais no campus, soltos, e isso dificulta um pouco descobrir como estão sendo mortos. Vamos instalar 39 câmeras para monitorar a área, uma medida que deverá ajudar a reprimir esses e outros crimes – diz o coordenador de segurança da UFRGS, Daniel Augusto Pereira.

Estudantes e funcionários choraram a morte de Alegria. Após a veiculação da notícia no Jornal do Almoço, da RBS TV, Flores recebeu dezenas de telefonemas e mensagens eletrônicas de solidariedade.

– As crianças perguntavam se ele era doutor de verdade. Eu dizia que sim, que era um cãozinho doutor para quem elas podiam contar tudo – lembra o professor Flores.

Olá,

Saiu uma nota no site Br-Linux sobre os vídeos que o grupo Tchelinux vem disponibilizando na internet. Gostaria de agradecer a todos os palestrantes que colaboraram p/ este acontecimento... :)

"E a persistente turma do Tchelinux continua dando o exemplo de não apenas realizar seus eventos descentralizados e sem aquele foco em pregar para os já convertidos, como ainda se esforçar para que o conteúdo apresentado chegue a todos os interessados que não têm como estar presentes aos seus eventos nas terras gaúchas."

0)  Close the Virtual Machine Manager or any instance of VM

1) Edit the xml config file from your VM

Example:

shell> vi /etc/libvirt/qemu/NAME_OF_YOUR_VIRTUAL_MACHINE_HERE.xml

Add the following lines:

Example:

<devices> (do not include this line)
    <emulator>/usr/bin/qemu-kvm</emulator> (do not include this line)
   <hostdev mode='subsystem' type='usb'>
     <source>
            <vendor id='0x04b4'/>
            <product id='0x1002'/>
     </source>
     </hostdev>

3) Save and restart libvirt
shell> /etc/init.d/libvirtd restart

4) Now just start your VM and test if your usb was detectd:

shell from VM> lsusb

5 ) shell> yum install kradio gnomeradio -y

kvm rocks!

2) shell> yum install kvm qemu virt-manager

3) Applications -> System Tools -> Virtual Machine Manager


Enjoy!

0)  Close the Virtual Machine Manager or any instance of VM

1) Locate vendor/product id from your device

Example:

shell> lsusb
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 004: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 003: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 002: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 002: ID eb1b:3212 "blah Technology, Inc. "
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Once you know your vendor and product id:

Vendor id:   0xeb1b
Product id: 0x3212

2) Edit the xml config file from your VM

Example:

shell> vi /etc/libvirt/qemu/NAME_OF_YOUR_VIRTUAL_MACHINE_HERE.xml

Add the following lines:

Example:

<devices> (do not include this line)
    <emulator>/usr/bin/qemu-kvm</emulator> (do not include this line)
     <hostdev mode='subsystem' type='usb'>
     <source>
            <vendor id='0xeb1b'/>
            <product id='0x3212'/>
    </source>
    </hostdev>

3) Save and restart libvirt
shell> /etc/init.d/libvirtd restart

4) Now just start your VM and test if your usb was detectd:

shell from VM> lsusb
Bus 001 Device 002: ID eb1b:3212 "blah Technology, Inc. "
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Done!

LD_DEBUG:

Useful environment variable in the GNU C loader is LD_DEBUG. This triggers the dl* functions so that they give quite verbose information on what they are doing.

Valid Options:

libs display library search paths
reloc display relocation processing
files display progress for input file
symbols display symbol table processing
bindings display information about symbol binding
versions display version dependencies
all all previous options combined
statistics display relocation statistics
unused determined unused DSOs
help display this help message and exit

To direct the debugging output into a file instead of standard output
a filename can be specified using the LD_DEBUG_OUTPUT environment variable.

Example:

shell> LD_DEBUG=all ls

Embedded GLIBC (EGLIBC) is a variant of the GNU C Library (GLIBC) that is designed to work well on embedded systems. EGLIBC strives to be source and binary compatible with GLIBC. EGLIBC's goals include reduced footprint, configurable components, better support for cross-compilation and cross-testing.

Perl Composer is a two-way visual tool used to design graphical interfaces for X-windows using Perl/GTK. The goal of it is to design a Visual Basic like tool for UNIX systems. Perl is a powerful language which can be used to replace the shell to control the execution of tasks on a Unix system. With Perl/GTK, we can design GUI front-ends for command line oriented utilities. However, a visual tool can save programmer's time in designing look-and-feel of programs and organizing the source code.
