I’m happy to see that more users are starting to use NAS devices (Network Attached Storage) to store and share their data, music, photos and videos within a household. Many people choose for a setup with a RAID 1 configuration which means that they have installed 2 harddisks that hold a copy of each others data (mirroring). Within a RAID 1 configuration, one harddisk can fail while the other still holds the data. You replace the faulty drive and your system / NAS is up and running again without any dataloss (usually you can still use it while one drive is faulty).

This RAID 1 protection is one step in safeguarding your data but, depending on your needs, you might want to think about additional protection. Now you are asking, why should I? Because think about what will happen when lightning strikes ruining you electrical devices, your house catches fire or a virus on your computer that starts deleting all data on your NAS. When you delete data, it is also removed from a Raid 1 configuration.

DO NOT UNDERESTIMATE THE RISKS !

Randy Halverson has created a nice timelapse video. Shot in RAW format, most shots were 20 seconds exposure F2.8 with 1 second interval between shots, for about 300 frames or so (several hours).

Photography Backgrounds DIY

Sometimes you need a nice colorfull background for your photography assignments. Especially with product or waterdrop photography, you might be in search for some background.

Create a new blank image in the size of your paper in photoshop and go to filters, render and render yourself some clouds (assign a fore- and background color) or in CS5 you can also find a fiber rendering option.  Print the image using your color inkjet or color laserprinter. I think you can best not use glossy paper and just cheap regular paper because glossy will give a glare when using flash.

This is a start, find out all kinds of filters yourself!

Het DNS (Domain Name System) is het systeem wat de internet adressen zoals www.vdsar.net vertaalt naar het bijbehorende IP adres zodat de website op onze computer getoond kan worden. Elke internet aanbieder heeft zijn eigen DNS server die je automatisch gebruikt als je van je internet aansluiting gebruik maakt. Dit is over het algemeen een vrij eenvoudige dienst zonder extra mogelijkheden voor beveiliging, blokkeringen, bewaking of logging.

OpenDNS is een aanbieder van een DNS systeem met veel meer mogelijkheden.
