I joined twitter today and there is already 9 people following me – thank you – within the same day. I have noticed that many people tend to follow those who follow them… This is a perfect ground for fraud, fishing and scam chains which I am sure it is being used already!.

I am going to do a little weekend experiment. To start with, I need subscribers, lets see how many I can gather within the weekend.

Here is my twitter

This trick becomes is very handy when transferring large files over the CLI and suddenly the connection is lost.

HOW-TO-RESUME-SCP-TRANSFER

scp does not support any kind of transfer recovery, so what can you use instead? rsync over ssh!

$ export RSYNC_RSH=’ssh [OPTIONS]‘
$ rsync –partial –progress <source> <destination>

Done! That’s it for today.
Cheers

No package ‘openssl’ found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables OPENSSL_CFLAGS
and OPENSSL_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

rtorrent depende de libssl-dev, así que primero asegúrate que lo tienes correctamente instalado

# dpkg -l |grep libssl-dev

En caso de que no lo tengas, apt es tu amigo (también puedes bajarte los fuentes y compilarlos tu mismo). Parece ser, que en algunas ocasiones esto resuelve el problema. Como en mi caso no lo hizo, os recomiendo que hagáis caso al error y apuntéis la variable PKG_CONFIG_PATH a donde tengáis instalado el pkgconfig. En Debian:

# export PKG_CONFIG_PATH=”/usr/lib/pkgconfig”

Ahora el ./configure, make y make install deberian ir sin problemas

# ./autogen.sh
aclocal…
configure.ac:22: warning: macro `AM_DISABLE_STATIC’ not found in library
configure.ac:23: warning: macro `AM_PROG_LIBTOOL’ not found in library
autoheader…
libtoolize… using libtoolize
automake…
src/Makefile.am:11: Libtool library used but `LIBTOOL’ is undefined
src/Makefile.am:11:   The usual way to define `LIBTOOL’ is to add `AC_PROG_LIBTOOL’
src/Makefile.am:11:   to `configure.ac’ and run `aclocal’ and `autoconf’ again.
src/Makefile.am:11:   If `AC_PROG_LIBTOOL’ is in `configure.ac’, make sure
src/Makefile.am:11:   its definition is in aclocal’s search path.

[......]

autoconf…
configure.ac:20: error: possibly undefined macro: AC_DISABLE_STATIC
If this token and others are legitimate, please use m4_pattern_allow.
See the Autoconf documentation.
configure.ac:22: error: possibly undefined macro: AM_DISABLE_STATIC
configure.ac:23: error: possibly undefined macro: AM_PROG_LIBTOOL
ready to configure

Para arreglarlo asegúrate de tener instalado aclocal y exportar la siguiente variable de entorno

# export ACLOCAL_FLAGS=”-I /usr/share/aclocal”

USO

Muy sencillo, lo de siempre

$ setxkbmap us # Cambia al layout de US.
$ setxkbmap es # Cambia al layout Español.

Recuerda al reiniciar sesión los cambios se perderán. Si quieres cambiarlo permanentemente, edita el xorg.conf

Instalacion

Muy sencillo, lo de siempre

$ wget ftp://mirrors.kernel.org/gnu/findutils/findutils-4.4.0.tar.gz
$ tar -xvvf findutils-4.4.0.tar.gz
$ cd findutils-4.4.0
$ sudo ./configure
$ sudo make
$ sudo make install
# Por ultimo
$ sudo updatedb

Ya podréis utilizar el locate como habéis echo siempre.

# awk -F. ‘{…}’
