In-depth support for all distributions of Linux is provided - we run SuSE/OpenSuSE, Slackware, Red Hat/Fedora/CentOS, Debian and Ubuntu Linux desktop systems and servers in our own office and anything from a simple configuration tweak to full installation, desktop workstations to file, mail and large web server clusters can be undertaken.

We can integrate your Linux systems into existing Microsoft Windows, Novell and AppleTalk environments, providing all network, Internet and server facilities. In fact, we can even set up your Linux server to provide all of these server functions, replacing 'real' Windows, Novell and Macintosh servers with a single low-cost PC-based solution.

But why merely integrate Linux into legacy IT environments? Why not replace that old environment completely? Linux, and UNIX systems generally, have often been regarded as being unsuitable for mainstream desktop use, being associated more with server and network applications. This is a myth and we feel strongly that modern UNIX-like systems can take their place on the office desk - or in the home - completely replacing standard Windows and Macintosh systems, with a range of office & technical productivity suites to match as well as a large and rapidly-growing catalogue of applications, including truly awesome games for leisure time.

As well as Linux, we support UNIX - in particular, Solaris, OpenSolaris, Digital/Compaq/HP Tru64 UNIX and FreeBSD but we also have experience of IRIX and AIX; Sun servers running Solaris play a major role in our network, firewall and off-site backup services while we have helped set up a PC-based parallel computing cluster of some 80 machines running FreeBSD UNIX.

Web coding of all types, from single pages through to complete multi-level sites, we specialise in fully interactive pages using advanced embedded scripting languages such as PHP and JavaScript to provide lively visual content, access to on-line databases and dynamic page control. We also have experience of Macromedia/Adobe Cold Fusion programming and are expert at integrating web scripts with server shell scripts to implement complex web functions.

A large part of our business is in supporting web hosting - we set up, configure and maintain web servers for both public Internet and private intranet use along with the associated database, file and network services and infrastructure; we recommend and use Apache httpd software on UNIX or Linux platforms, compiling customised versions to support special requirements such as secure E-commerce transactions, script language support, databases and embedded graphics functions. We build new servers to order and can repair and upgrade most servers irrespective of manufacturer.

Backed up by a very comprehensive and reliable remote monitoring/alerting service written & developed by ourselves, remote systems administration is our speciality and we will look after your UNIX and Linux systems wherever in the world they may be and whenever you want - at any time of day or night, 365 days a year - and in complete confidence. For optimum security, all of our work is backed up by off-site archives, allowing us to restore system configurations rapidly in the event of a system problem.

On-site support and out of hours site visits are a normal part of our work and and being based in north London, we have rapid access to data centres in the City, Docklands and other parts of London at any time of day or night, making full use of mobile Internet data facilities when we are away from base or out of the UK to maintain continuity of service.

Today we are responsible for an increasing number of servers and associated infrastructure co-located at data centres in the London area including Telehouse Europe, Sovereign House, Canary Wharf and Harbour Exchange in the Docklands and in central and east London, hosting a total of over 3300 web sites, some of which are well-known household names serving up to 5 million hits/day.

We are well versed in MySQL database programming & administration but we haven't forgotten our many years of xBase (dBase, FoxBase and FoxPro) programming experience. This list is by no means exhaustive and we'll consider database projects using other DBMS depending on the task in hand and the environment - try us!

We can undertake a variety of other projects in addition to our core activities so if you have something unusual in mind, why not contact us to discuss your requirements? We are sometimes asked if we support Windows; the short answer is no, we do not provide support for any kind of Microsoft Windows on desktop PCs or laptops. However we are currently running and maintaining a large Windows server farm on behalf of a client and we would be prepared to support Windows Server 2000, 2003 and 2008 on server hardware although it is important to realise that Windows is 'high maintenance' compared with Linux or UNIX, which has obvious implications for costs; we certainly would not recommend the use of this operating system. And we do of course support the X Window System (not to be confused with Microsoft Windows).

Established in 1985 for the small-scale manufacture of solid state high voltage DC power supplies for incorporation into instrumentation used for solid state physics research, Time Domain Systems borrowed its name from one of the main projects - research into the dielectric properties of insulating materials in the time domain. Funded by US President Reagan's Star Wars project, our involvement gradually broadened into designing & building specialist computer interfaces for North Star Horizon and other S-100 bus-based computers running CP/M-80 and then writing the data acquisition software to make them useful.

Since then, we have evolved from being a purely electronics R&D facility to our present day status as an independent UNIX/Linux systems consultancy. Along the way, we have made good use of a decade of prior experience in acoustics research, having been commissioned to design & build amplifiers and speaker systems for the music and cinema industries, written bespoke assembly language software for acoustics, solid-state physics and biochemical research projects, developed hardware and software for commercial enterprises in the educational market sector and more recently, created custom hardware interfaces and software for bio-medical and physiology research, as well as a hydrogen-producing cyano-bioreactor plant. But from about 1994, our focus switched to the rapidly expanding Internet network arena and we were soon involved in implementing & running dial-up computer services, large-scale network installation projects and the use of first Linux and then UNIX servers to support these operations.

With a wealth of past experience in a number of distinct yet broadly-related areas encompassing electronics, acoustics, physics and computing-related disciplines, we are well placed to undertake the more unusual projects.
