The Internet Jigsaw

Internet and internet systems are like one big jigsaw. Every piece has to be on the right place. If just one piece isn't right than you won't get the result you hoped for.

E-commerce specialist

I am a E-commerce specialist and can help you with many questions about this fantastic way of selling you products or services. In the late '90 I started a web shop for selling white-goods over the Internet on the Dutch marked. I was the first one who did that and there was no software like Drupal of OS-Commerce. I had to invent it all by myself. It was a great time!.
The shop was very successful and some day a big company made me an offer that I couldn't refuse. So I sold my e-commerce business.

Now I use my knowledge to advice and help other e-commerce companies to get better, grow and make more profit. My strength is the combination between technique and commerce.

Drupal D7 Ellfinder elfinder-7.x-2.x-dev error "Invalid backend response.Data is empty"

I have a very strange situation with Elfinder. I developed a Drupal D7 website on a development (Ubunt 12.04) server. Everything, including CKEditor and Elfinder works perfect. I migrated the website (file system and mysql database) to a Zpanel Linux Ubuntu 12.4 server and I didn't get elfinder working any more.

How-To Resize mailbox size in Zpanel on Ubuntn 12.04

Running a Zpanel on a Linux server and you want to resize the users mailboxes? This is how to do that.

The standard size of mailboxes in Zpanel is 200Mb

You can change the size of new mailboxes in:
Admin -> module admin -> Mail Config -> Max Mailbox Size
Remember that only new created mailboxes will have this size!

Create test files of specific size

Sometimes you need file of an exact site for testing purpose like an email attachment.

Here is how you make them in Linux command line:

dd if=/dev/zero of=file_5Mb.txt bs=1k count=5120
dd if=/dev/zero of=file_7Mb.txt bs=1k count=7168
dd if=/dev/zero of=file_8Mb.txt bs=1k count=8192
dd if=/dev/zero of=file_8.8Mb.txt bs=1k count=9011

Create test files of specific size

dd if=/dev/zero of=file_5Mb.txt bs=1k count=5120
dd if=/dev/zero of=file_7Mb.txt bs=1k count=7168
dd if=/dev/zero of=file_8Mb.txt bs=1k count=8192
dd if=/dev/zero of=file_8.8Mb.txt bs=1k count=9011
dd if=/dev/zero of=file_9Mb.txt bs=1k count=9216

Fotografie

Fotografie is al sinds mijn jeugd een hobby. In de jaren '70 fotografeerde ik met een 2-hands grootbeeld spiegelreflex camera. Echt een oudje en ondanks zijn leeftijd een prima camera. Dat was in die tijd normaal dat je naast je camera ook een aparte, losse belichtingsmeter bij je had. Immers met de camera kon je niets ander dan scherpstellen, de sluitertijd en het diafragma instellen.
