Ich bin MMT

After 6 years at my job working as a web developer I decided to take a break and go back to university. To the University of Applied Science in Salzburg to be precise. I’ll get a master’s degree in Multimedia Technology and solidify what I learned in practice while working in that field and go way outside my comfort zone by getting deeper into computer science, machine learning, project management, etc.

I guess that's it

After six years of service my Macbook Pro (2006) is broken. It was in a shoddy state for a while, but now it’s time for retirement.

Hello iPhone 4S

This new iPhone 4S will relieve my iPhone 3G of its duty. When helping a friend move into his new place it started raining and somehow water got between the actual screen and the covering glass resulting in a lot of pixel errors. The new iOS versions make it slower and more frustrating to use.

How to split and join large files

Sometimes it might be necessary to chop up a large file into several parts (e.g. to place it on drives that are to small for the whole file). Keep in mind that corruption to any of the parts will result in a corrupt file once it is stiched back together.

To split a large file:

split -b 1m /path/to/large/file /path/to/output/file/prefix

-b defines the size of the chunks (1m stands for 1 megabyte). Please refer to man split for all the options the tool offers.

This will give you a bunch of files whose names start with the defined prefix and a incremental suffix (starting with aa depending how many parts need to be created).

To join the parts back into one file:

cat prefix* > new_filename

Writing and reading harddrive images

Be careful with these commands, you can lose a lot of data quickly! Be mindful of the required disk space for any of those operations!

With Unix tools its pretty straight forward to create and play back images of hard drives.

Create an image of a harddrive:

dd if=/dev/hda of=/mnt/hdb1/myimage.img

Write the image back onto the harddrive:

dd if=/mnt/hdb1/myimage.img of=/dev/hda
