I am a professional programmer and web application tester. I'm sort of a jack of all trades because I work with almost every technology under the sun as a hobby, so most of the questions that appear on StackExchange sites are intensely interesting to me, and many of the answers that I come up with will prove useful to me in my pursuits in the future.

I have professional and serious hobby experience with system administration (client and server), desktop applications and web programming (mostly in higher level languages), audio processing and encoding, functional validation, and application security testing. My degree is in Computer Science but my interests are much broader than most of my peers.

Chances are, if you've got a question related to technology, I'm right there with you -- either I have the same question or have had it at some point in the past. I'll try my best to impart my own personal experience in the hopes that it is useful, but be wary that I sometimes jump the gun and post experiences that may not represent actual fact. I encourage everyone to verify the information they read on the internet before making important decisions based upon it, and my answers are no exception.

comment Validation and Source Tables for T-code MB52 in ECC
SAP itself is completely off-topic for Super User. SU is for "computer enthusiasts and power users". When we use the term "user", we mean regular home users running home software, such as productivity software, web browsers, operating systems, content creation software, entertainment software, and so on. Enterprise finance / management software is so far out of range of acceptable topics for SU that I voted to close it. Please stop asking questions about SAP on SuperUser.

comment Changing partition table, Centos 6.3 on Hetzner Server
I complained to Hetzner about installimage's limitation of not supporting GPT a while ago and they said they were working on adding GPT support but it might be a while. Meanwhile you can edit a local copy and make the needed changes (if you're brave); it's just a perl script.

comment Migrate raw disk image over LAN
It's gonna take a while. Realized I have a gigabit port with a 100 Mbit/s allocation. Crap.

comment Migrate raw disk image over LAN
That would also eliminate the spurious/scary "No space left on device", since it's going to resize /dev/sda3 down to about 1.3 TB and will be copying it into a partition on the destination that's expecting to hold about 2.9 TB.

comment Migrate raw disk image over LAN
Awesome! I'm OK with copying the partition's free space because these instructions meet all of my other criteria. Although, wouldn't just resizing the filesystem and the partition itself on oldserver eliminate the need to copy all the free space? I don't care about /boot because it's so small, but for / at least, I could do that, right? Just set the partition's end sector to equal what sector resize2fs sets the end of the FS sector to. Well, sector, block... probably block. But thanks for this! This is great!

comment Migrate raw disk image over LAN
mdadm? I'm using hardware RAID. And I have no idea what AOE is, and have never used iSCSI. I don't think my servers are in the same broadcast domain, just in the same datacenter. There's at least one or two switches between the servers.

comment Migrate raw disk image over LAN
I think partimage can do raw copies that are filesystem aware, but it doesn't support ext4. So there goes that as an option... rsync is looking nicer as an option, as long as it preserves all discretionary access controls (a la chmod) and can cleanly copy over symlinks and device files...
