So this is just going to be a total rant. IPv6 is, in theory, a solution to many things, including the dwindling IPv4 address space.

2020-09-04 9 min read Tech explained Version control Teknikal_Domain Unable to load comment count

So here’s a fun one. Have you ever noticed that even for huge changes to a repository, a git push only sends over a few kilobytes, maybe a few megabytes at most? If you’re familiar with the internals of git , you know that git stores an entire copy of the new file on commit. So how are these changes so small?

Or, how I learned to stop worrying and love the BPDUs.

Spanning Tree Protocol, as mentioned previously , is a protocol used by switches to build out a loop-free logical topology of an Ethernet network. The protocol itself is built off of a concept called, well, a spanning tree.

BorgBackup: (TODO: Insert Borg Joke Here)

2020-08-09 5 min read Cool stuff Tech explained Teknikal_Domain Unable to load comment count

I was really fighting with my inner self to have a straight-forward title for this one, but alas, resistance is futile.

BorgBackup, or, for short, just “Borg”, is a relatively fast (more on that later), efficient, secure, and authenticated way of backing up multiple devices either on a single network, or even across networks (you’ll see, again, later). This is currently what I use for backing up my stuff, and, well, it’s just cool, and definitely something you should take a look at.

And for the record: this is something that I’ve struggled with for about 8 months, and I think it’s getting close to the point where I really should just give up… but I won’t.
