Are we DevOps, or SRE?

SRE Vs. DevOps has been a ranging battle for quite sometime now. Ask any operations or infra team in today's bubbling tech shops and, they will tell you, without a flutter, that they are SRE. Scratch them a bit more and, they will tell you how they follow the SRE principles with stories from their daily grind and link them to Google's SRE handbooks. Then drop the big question, "But isn't the same thing DevOps too?" and see them getting confused and incoherent a bit. Now, if you ask, "Or maybe, yours is more of a hybrid model than pure DevOps/SRE?". Now, you might have turned a few heads and even made some ponder further away. Managing "Operations" as a disciplined practice has always been an arduous task. Many companies today have dedicated operations departments engaged in planning and executions, but more often than not, they fail badly. The tech operations landscape is no different. There are always, generally unsolved questions about how t

Does Linux Need a Defragmentor?

In computing terminology, file system fragmentation sometimes also called file system aging, is the inability of a file system to lay out related data pieces sequentially or contiguously on the disk storage media. This is an inherent problem in storage-backed file systems that allow in-place or live modification of their contents. This is one of the primary use cases of data fragmentation.  File system fragmentation increases disk head movement or seeks required for fetching the whole file, which are known to hinder throughput and performance of disk reads and writes. As a remedial action, the motive is to reorganize files and free space back into contiguous areas or blocks so as to keep all pieces of a file data together at one place, a process called defragmentation. Ok, give me an example please? let's attempt at explaining in a simple, non-technical manner as to why some file systems suffer more from fragmentation than others. Rather than simply stumble through lots of dry te
