Swap Alt and Windows keys with xmodmap?

The problem: I have a Mac keyboard where the Alt/Win (i.e. Option/Command) keys are inverted compared to a regular PC keyboard, and I'd like to swap them.

The answer:

[codesyntax lang="bash"]

# clear all options
setxkbmap -model "pc105" -layout "us,se" -option ""  

# set the Apple keyboard
setxkbmap -rules "evdev" -model "pc105" -layout "us,se" -option "terminate:ctrl_alt_bksp,lv3:rwin_switch,grp:shifts_toggle,altwin:swap_lalt_lwin"



And another one which I call when I'm back on a normal keyboard:

[codesyntax lang="bash"]

# clear settings
setxkbmap -model "pc105" -layout "us,se" -option ""

# pc keyobard
setxkbmap -rules "evdev" -model "pc105" -layout "us,se" -option "terminate:ctrl_alt_bksp,lv3:rwin_switch,grp:shifts_toggle"


How to enable syntax highlighting in less

I wanted to have syntax highlighting for a php file I was debugging. Source-highlight given a source file, produces a document with syntax highlighting.

These are the output formats already supported:

  • HTML
  • MediaWiki (new)
  • ODF (new)
  • ANSI color escape sequences (you can use this feature with less)
  • DocBook

These are the input languages (or input formats) already supported (in alphabetical order):

  • Ada

  • Applescript
  • Awk
  • Autoconf files
  • Bat
  • Bib
  • Bison
  • C/C++
  • C#
  • CakePhp templates

Exactly what I needed!

[codesyntax lang="bash"]

apt-get install source-highlight
echo "" >> ~/.bashrc
echo "export LESSOPEN=\"| /usr/share/source-highlight/src-hilite-lesspipe.sh %s\"" >> ~/.bashrc
echo "export LESS=' -R '" >> ~/.bashrc


Note: Be sure this line isn't present in your .bashrc because it will interfere with source-highlight:
[codesyntax lang="bash"]

 [ -x /usr/bin/lesspipe ] && eval "$(lesspipe)"



Prozilla - Linux Download Accelerator

Prozilla Download Accelerator is a multi-threaded download accelerator for Linux which supports both HTTP and FTP protocols and because it makes multiple connections to the server and downloads the file in portions, thus giving a much better speed rate than the conventional download programs which use a single connection, increases download speeds with up to 200-300%.

Resuming connections is fully supported and customizable.

Because it based on ncurses, Prozilla is also a lightweight download accelerator.

1. Get prozilla 2.0.4.

[codesyntax lang="bash"]

git clone https://github.com/totosugito/prozilla-2.0.4.git


2. Install required packages

[codesyntax lang="bash"]

apt-get install autoconf build-essential libncurses5-dev


3. Installing from source code

[codesyntax lang="bash"]

cd prozilla-2.0.4
make install


4. Troubleshouting. If an error occurs:

make[4]: Leaving directory `/home/user/prozilla-2.0.4/libprozilla/src’
make[4]: Entering directory `/home/user/prozilla-2.0.4/libprozilla’
make[4]: Nothing to be done for `all-am’.
make[4]: Leaving directory `/home/user/prozilla-2.0.4/libprozilla’
make[3]: Leaving directory `/home/user/prozilla-2.0.4/libprozilla’
make[2]: Leaving directory `/home/user/prozilla-2.0.4/libprozilla’
Making all in src

-c -o main.o `test -f ‘main.cpp’ || echo ‘./’`main.cpp; \
then mv -f “.deps/main.Tpo” “.deps/main.Po”; \
else rm -f “.deps/main.Tpo”; exit 1; \
In file included from main.cpp:39:
download_win.h:55: error: extra qualification ‘DL_Window::’ on member âprint_status’
make[2]: *** [main.o] Error 1
make[2]: Leaving directory `/home/user/prozilla-2.0.4/src’
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/user/prozilla-2.0.4′
make: *** [all] Error 2

And the solutions...

Looks like the problem of error occurs because the compatibility of the compiler the GNU C/C+ + latest version, to avoid this error edit the file src/download_win.h and replace:

void DL_Window::print_status(download_t * download, int quiet_mode);


void print_status(download_t * download, int quiet_mode);

5. Do you want to make this a deb package?

[codesyntax lang="bash"]

apt-get install build-essential automake autoconf libtool pkg-config libcurl4-openssl-dev intltool libxml2-dev libgtk2.0-dev libnotify-dev libglib2.0-dev libevent-dev checkinstall
./configure && make && sudo checkinstall
