    To Jimena and her little brothers Anita and Fidel.

    Jimena liked to play Ceed Universe, but some times it stop working... so... for months I was trying to install it on my computer using Debian 10, and I couldn't make it work emulated or with a chroot. Searching in Internet, I found 4 similar games: Colobot, Minetest, Code Combat, Liberation Circuit.


    It work out of box!

    apt-get install colobot


    I install it from debian backports, because the package in the normal repository use python 2.

    echo "deb http://deb.debian.org/debian buster-backports main" >> /etc/apt/sources.list
    apt-get update
    apt-get -t buster-backports install minetest

     Code Combat

    Need to be updated... but with these commands works...

    curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash
    nvm ls-remote
    nvm install 8.15.1
    node -v
    curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add -
    echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list
    apt-get update && apt-get install yarn
    git clone https://github.com/codecombat/codecombat.git
    cd codecombat
    git remote add -f upstream https://github.com/codecombat/codecombat.git
    echo '{ "allow_root": true }' > /root/.bowerrc
    yarn install --ignore-engines
    yarn run webpack -- --watch
    yarn run proxy

    Liberation Circuit 

    It seems to be a awesome game!!!

    apt-get install liballegro5-dev liballegro-image5-dev liballegro-dialog5-dev \
                    liballegro-audio5-dev liballegro-acodec5-dev
    git clone https://github.com/linleyh/liberation-circuit.git
    cd liberation-circuit

    Don't forget the excelent programs to learn: scratch and python3-tk.


  • My Parabola gnu/linux laptop

    05/10/2016 at 16:52 3 comments

    For many months I was looking upgrade my old laptop. I was using Debian but the free nvidia video driver died frequently, so I install Parabola trying to fix that problem.

    When I use Parabola I loved it. It is a better and easier alternative for develop.

    Parabola and their newer versions of the packages didn't fix my video problem, and also I can't install the private driver of my wifi card or change that card.

    So I buy a Razer Blade Stealth with intel video, and change the wifi card. I buy a wifi card from: https://www.thinkpenguin.com/catalog/wireless-networking-gnulinux

    I read the Parabola beginners guide, but next are what I exactly did.

    I first make a bootable usb with the dd utility and disable bios usb secure boot on the Razer laptop.


    parted /dev/nvme0n1p
        mklabel gpt
        mkpart ESP fat32 1MiB 513MiB
        set 1 boot on
        mkpart primary ext4 513MiB 15.5GiB
        mkpart primary linux-swap 15.5GiB 19GiB
        mkpart primary ext4 19GiB 100%
    mkfs.vfat -F32 /dev/nvme0n1p1
    mkfs.ext4 /dev/nvme0n1p2
    mkswap /dev/nvme0n1p3
    mkfs.ext4 /dev/nvme0n1p4
    Install base:
    swapon /dev/nvme0n1p3
    mount /dev/nvme0n1p2 /mnt
    mkdir /mnt/home
    mount /dev/nvme0n1p4 /mnt/home
    pacstrap -i /mnt base
    genfstab -U -p /mnt >> /mnt/etc/fstab
    arch-chroot /mnt /bin/bash
    pacman -S grub efibootmgr
    nano /etc/default/grub
    mkdir /boot/efi
    mount -t vfat /dev/nvme0n1p1 /boot/efi
    grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=parabola --recheck
    cp /usr/share/locale/en\@quot/LC_MESSAGES/grub.mo /boot/grub/locale/en.mo
    grub-mkconfig -o /boot/grub/grub.cfg
    efibootmgr -c -d /dev/nvme0n1p1 -l /EFI/parabola/grubx64.efi -L "parabola"
