Computer Hardware and Solutions

We still supply custom PC's to client order specific requirements.


We still repair client PC\'s that have obscure faults or just mystify their users.


In summer here in SA, I generally have to replace the power supply that has blown due to a lightning surge that came down the mains wire.


Quite often these days, I am asked to do data recovery for clients.
This usually means leaving the offending unit with me for assessment and quotation.
Fortunately the modern PC is quite resilient and reliable, so the recovery of data is reasonably economic.
However a badly damaged disk or hard disk will take a lot of time to analyse and recover data.
This can quite often put the data beyond the reach of the client. Remember to backup regularly.

Of course if this is HR or Payroll data that SARS has asked the company for, I am your man.  Confidential data will be kept confidential.
Recovery and restoration of payroll data has been done recently for a large corporate client that had backups on 3.5" disks!

The 'Web Checker' database.

[Updated at 07 and 37 minutes past the hour.] The data shown on pages here is collected by a computer at JBCS, purely as a technical exercise and shows no favour or economic tie to that web site. The data is stored in a MySQL database on another computer for distribution to others.

Over the last six months or so (2009), it has become obvious that those sites using the 'mtnbusiness' (Neotel/MTN) network are appreciably quicker than the others using the Telkom network. If you 'Traceroute/Tracert' the lower sites on the graph, you will see that your route to the site is via the 'mtnbusiness' network. *** Your web site can be added to the list for future study.*** *** Your links can also be checked for 'breakages' automatically.*** If you wish to add your site, please email the 'chief penguin/budgie' - John Brock.

The Planner/Calendar

Screenshot of Planner/Calendar:

This is a screenshot of the Planner/Calendar input application, which uses a MySQL database to store events. The table on the MySQL database uses identical fields to an Outlook export to allow export/import to Outlook. The application shown here uses ODBC to communicate with the event calendar table for the West Rand Amateur Radio Club. The calendar is then rendered on their home page using PHP and an interface to MySQL.
