Recently I switched jobs to a startup that Allows me to explore all the essential tasks within (any) company and make a PHP webbased application to administer it all. This places me in the position to define and explore all Business processes and manage it into a (single) database.

With just 3 servers to administer a 25+ person network. No this is not like the Data Centres (EPO & EU) I managed before, but it allows me to spend time aligning IT with Business.

After 3 months I setup a basic database with any needed tables.
With a MSSQL to PHP tool I quickly and without any effort I built all table administration pages. spend a month on optimising query effort like external index files and if needed data can be split among several database servers.

As there is current data, it will be needed to import it and distribute it into the new tables. a single script does this for me. and I expect all personnel to be fully working with the new application within 6 months for which I still have to develop +- 36 modules.

A rather quick development effort with results in a year.

Disk Backup

2008-04-26T19:07:00.002+02:00

Day before yesterday we had a disk crash on one of our internal mailservers.
The metadb failed on a raid 1 mirroring disk, problems should not have been so big.
However the synchronisation worked not so well. Solaris keeps a record of each disk and in which scsi slot it is located. Therefore both disks synced with eachother making the filled disk sync with the empty one, moving all data to Lost+Found. No way everything would fit in there be easily restored.

2 weeks before I had to restore a mailbox of one of our users, resulting in a 2 day tape restore.
The old LTO drives are slow. I did not want to spend another 2 days restoring mail for users in the future. So I wrote a little script that makes by default a UFS level 1 dump to harddisk, unless it does not see a level 0 dump. Making level 1 backups is quick and is done twice a day outside office hours.

It was this disk backup that saved us on the second day, ufs restoring all users email in just 2 hours (level 0 and 1). There only remained a small issue with the mail service. This isn't your typical sendmail but a special mail service used by some of the larger ISPs. Some users where left with broken mails FETCH issues with imap and a broken POP2 fetch rfc822 implementation remnant from netscape, which microsoft Outlook implemented as well.

The internet made the world a lot smaller. Communcations to any remote place are possible. and with web applications like Google earth really shows how small our world has become. Since communication has been made so easy, we receive much more information on all sorts of topics, but most of all people tend to communicate without saying anything. I have been online since 1988 and to me it has not changed much at all over time. Any network with people tends to become social. Sure we have improved things like graphics and higher connection speeds..

Here I mostly would be talking about my social things, Automation and Virtualisation, Data Centre Management. And projectamin, the socialable devices of the future.
