Computing, devices and open hardware

A life online · Alejandro Rivero

Recovered experiments from an old server

2008–2012 · Restored September 2026

Six recovered projects add webcam-photo widgets, a pre-launch Ibercivis page, Facebook event graphs, printable tweets, a seasonal-search map and collective-intelligence interface prototypes. The exhibits preserve documentation and selected images, without restarting old camera, upload or social-network services.

The 2008 CV extracts also record Applesoft BASIC in 1983, Macintosh support and database work in the 1980s, and OCCAM/Transputer work around 1990.

Hardware Libre, tecnología y derechos

2003-06-01 · Original

A dialogue on DRM, free processors, fabrication and local workshops, published as arivero on Libertonia. My politics page links the essay and an English translation at OpenCollector. The displayed publication date is 1 June, although the URL contains 29 May.

A webcam mouse, before the device became ordinary

2003–2004 · Surviving copy

Documentation of two student projects using a coloured glove, image moments and Visual Basic to control the Windows pointer. The page retains links to code versions, reports and a presentation, and signs itself with arivero at posta.unizar.es.

Ciclorail: a bicycle on railway tracks

Undated project pages · Surviving copy

A small project site documenting prototypes and trials around El Poyo del Cid, Villar, Peracense and Almohaja, with links to photographs and videos. The introduction connects practical construction with the right to understand technology. The travel section follows the outings and links their individual accounts.

DjVu Reader for the Sony Librie

2006-01-25 · Original discussion

MobileRead announces version 0.1 and credits arivero as its programmer. In the discussion I explain the launch scripts, saving the current page and problems with keyboard input. The announcement also points back to the earlier release message.

What software ships inside the iLiad?

2006-07-02 · Original discussion

A request to inspect the forthcoming reader's documentation for Linux and other free-software components and versions: an early part of the discussion about source availability.

A wiki for iLiad early adopters

2006-07-14 · Original discussion

Organising a MediaWiki table of owners and prospective buyers, alongside the technical work on the reader.

iLiad USB hacking

2006-07-19 · Original

Inspecting the shipped USB modules and the distinction between host and device operation, in pursuit of support for a USB keyboard.

Opening the iLiad to web browsing

2006-07-21 · Contemporary report

A contemporary MobileRead report credits arivero and other contributors with ways to enable network access beyond the vendor's delivery service.

Icons, manifests and keyboard input

2006-08-01 and 2006-08-08 · Original discussions

Two parts of making early electronic-paper devices usable: customising the iLiad interface and revisiting input for the Librie DjVu reader.

The iLiad firmware 2.7 discussion

2006-10-19 · Original discussion

A historical thread about a command-execution flaw, user control of the device, disclosure and anticipated firmware changes.

PDF reflow, source releases and document search

2006-10-26 to 2006-12-01 · Original discussions

Practical follow-up on free PDF-reflow tools, the scope of the iLiad source release, and searching document contents with command-line tools.

Transcript Search: making video text discoverable

2013-07-11 · Original announcements

Announcements on Libertonia and Conjeturas connect the AGPL project to its original transcriptsearch.com.es address. The repository survives even when the former service address is unhelpful.

Mail clients, 1993–2021

Dated from the X-Mailer headers of my own messages and from the modification dates of the profiles left on old machines

A plain mailer on the computing-centre account in December 1993. elm 2.4 from 1994, its Mail/ folder of saved messages still there in 2003 and its elmrc touched for the last time on Christmas Eve 2003. tin for Usenet in April 1997. Netscape 2.0, 3.01 and 4.0x on Solaris workstations at Telefónica I+D, November 1997 to November 1998, the year I also read the Mozilla mail-news group. Netscape over IMAP in 2000. TeamWARE Embla at the Universidad Carlos III and nmh to unpack the course mailbox, June 2001. pine 4.04 from 2001, whose debug log records the last session to the minute, 19 March 2003 at 21:30, when it moved the spool into ~/mbox; Netscape 4.77 on Windows 95 in parallel; Evolution in 2001 and 2002. Then a procmail file in 2005 that filtered arXiv dailies and one journal manuscript number, and a .forward to Gmail on 31 December 2007. After that, every client installed on a new machine was opened and left empty: KMail in 2011, Opera in 2010 and 2011, Claws in 2013, Thunderbird in 2019, Evolution again in 2021. The one exception is Evolution on an eeePC netbook, which sent two messages through the Gmail account on 5 February 2011 and was not used again. The mail had moved to the browser.

The messages themselves, 5,033 of them from 1993 to 2004, stay private; the chronology carries the dated facts they establish.
