What is RoHS?

Working in partnership with the policy lead at BERR (The Department for Business, Enterprise & Regulatory Reform), NWML is the UK Enforcement Authority for the Restriction of the Use of Certain Hazardous Substances in Electrical and Ellectronic Equipment Regulations 2008 (the “RoHS Regulations”). These Regulations implement EU Directive 2002/95 which bans the placing on the EU market of new electrical and electronic equipment containing more than agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants.

Manufacturers need to understand the requirements of the RoHS Directive to ensure that their products, and their components, comply.

List of TCP and UDP port numbers

...info de la wikipedia...

In computer networking, the protocols of the Transport Layer of the Internet Protocol Suite, most notably the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP), but also other protocols, use a numerical identifier for the data structures of the endpoints for host-to-host communications. Such an endpoint is known as a port and the identifier is the port number. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.^[1]

The Slackware Linux Project

What is Slackware Linux?

The Official Release of Slackware Linux by Patrick Volkerding is an advanced Linux operating system, designed with the twin goals of ease of use and stability as top priorities. Including the latest popular software while retaining a sense of tradition, providing simplicity and ease of use alongside flexibility and power, Slackware brings the best of all worlds to the table.

Originally developed by Linus Torvalds in 1991, the UNIX®-like Linux operating system now benefits from the contributions of millions of users and developers around the world. Slackware Linux provides new and experienced users alike with a fully-featured system, equipped to serve in any capacity from desktop workstation to machine-room server. Web, ftp, and email servers are ready to go out of the box, as are a wide selection of popular desktop environments. A full range of development tools, editors, and current libraries is included for users who wish to develop or compile additional software.

The Slackware Philosophy Since its first beta release in April of 1993, the Slackware Linux Project has aimed at producing the most "UNIX-like" Linux distribution out there. Slackware complies with the published Linux standards, such as the Linux File System Standard. We have always considered simplicity and stability paramount, and as a result Slackware has become one of the most popular, stable, and friendly distributions available.

Slackware Overview

Slackware Linux is a complete 32-bit multitasking "UNIX-like" system. It's currently based around the 2.6 Linux kernel series and the GNU C Library version 2.7 (libc6). It contains an easy to use installation program, extensive online documentation, and a menu-driven package system. A full installation gives you the X Window System, C/C++ development environments, Perl, networking utilities, a mail server, a news server, a web server, an ftp server, the GNU Image Manipulation Program, Mozilla Firefox, plus many more programs. Slackware Linux can run on 486 systems all the way up to the latest x86 machines (but uses -mcpu=i686 optimization for best performance on i686-class machines like the P3, P4, Duron/Athlon, and the latest multi-core x86 CPUs).

ExpressPCB- printed circuit boards easy, fast, inexpensive and fun.

ExpressPCB The concept of ExpressPCB is to make designing electronics with printed circuit boards easy, fast, inexpensive and fun. Before now, this has not been the case for several reasons. Es un sitio que te permite bajar un software (cad) para fabricar placas (pcb) para electrónica. Después puedes subir tu diseño a la web y, previo pago de un buen dinero, recibir en tu casa las placas ya fabricadas. Interesante.
