From How to improve disk I/O performances with VMware Workstation 5:

Memory trimming
Workstation checks which part of the guest OS virtual memory is not used and allocates it back to the host OS. This permits to have more concurrent virtual machines running but everytime the guest OS asks back for its memory it suffers a performance [...]

I have had problems trying to compile ssldump-0.9b3 against OpenSSL 0.9.7.
To fix it, I made the following patch:

Scenario
This article describes how to create a secure network-level transport between two hosts. All traffic sent between both hosts will be encrypted automatically as in enters the TCP/IP stack at the network (IP) level by using IPSec Encapsulating Security Payload (ESP) protocol.
For more details about IPSec, read IPSec pilot between glass and teapot.

Interesante traducción de un artículo de Bruce Schneier realizada por la gente de Kriptópolis.
Resumiéndolo en pocas palabras, si la industria de seguridad no es capaz de protegernos contra ella misma, ¿qué podemos esperar? Los fabricantes de software anti-virus, anti-spyware y anti-todo han sido, a día de hoy, incapaces de evitar que un CD de música [...]

From the stunnel manual page:
The stunnel program is designed to work as SSL encryption wrapper between remote clients and local (inetd-startable) or remote servers. The concept is that by having non-SSL aware daemons running on your system you can easily set them up to communicate with clients over secure SSL channels.
stunnel can be used to [...]

OpenSSL command-line tools offer a lot of functionality. OpenSSL can generate private keys and their corresponding public key certificate requests, can sign those certificate requests, publish certificate revocation lists (CRLs), convert between several encoding formats like DER, PEM, PKCS#12, etc.
In this article I will describe how to use OpenSSL to set up a Certificate Authority [...]

Acabo de recibir en mi cuenta de correo un correo basura. Otro más, solo que este es diferente de los demás.
Este correo, en lugar de utilizar el típico mensaje de texto — que dice aumentar la longitud de alguna parte de mi cuerpo, venderme algo que no necesito (como una pastilla azul) o solicitarme que [...]

I have found a very interesting post on integrating both Mac OS X, Linux and Windows under a Windows Active Directory infraestructure: Mac OS/Linux/Windows Single Sign-On.

SSLTunnel is a beautiful piece of software used to create an SSL/TLS VPN between two hosts, usually a client host and a VPN concentrator or server. Inside this tunnel, the traffic between the client and the server gets encapsulated inside PPP frames which are encapsulated inside the SSL/TLS tunnel. The tunnel itself is built using [...]

Ayer conocí a una Fiscal y no pude evitar la curiosidad de preguntarle cuál era su opinión al respecto del Derecho de Copia Privada y las acusaciones de ilegalidad que ciertas Entidades de Gestión hacen contínuamente.
Me dijo que, tal y como otras personas han reiterado una y otra vez en sus bitácoras, en entrevistas en [...]
