double122on Ask HN: What do you use to backup your data?

For Linux backups, you might be interested in this article, if you haven't already read it:

http://www.mikerubel.org/computers/rsync_snapshots/

The combination of cron, rsync and hardlinks, makes for incremental backups with versioning and minimal storage space, all over ssh.

double122on Ask HN: Online presence: pseudonym or real name?

a pesudonym is somewhat unprofessional

Thanks, I think this is what is swaying me more towards just putting things under my own name.

double122on FBI wants public help solving encrypted notes from murder mystery

I love python (I did this in python):

https://github.com/d122/Murder-Mystery

But you are both correct, the indentation, circling etc. may be important, but I just wanted to get the letters down initially. Start with the basics and work up!

Ahh great, thanks for sharing.

I've added a few bits to a git repo:

https://github.com/d122/Murder-Mystery

Just some basic python code in there for now.

I'll have a look at the differences in our transcriptions when I get back from work tomorrow, and maybe try and think of some more angles to approach this.

That's a valid point. I appreciate that it may be nothing, but that won't discourage me from having a little play with it.

Here's a CSV containing the frequency of all words from 2 upto 10 letters http://d122.com/murdermystery/words.csv if anyone's interested.

"rcbrnse" five times?!

It's just a frequency count of the letters in the transcriptions I did. Obviously my transcript may not be perfect, but I was pretty confident with most of the letters.

This was just my first observation and I thought it was interesting enough to post.

I thought this could be a fun 'challenge'...

I'm inclined to believe that this is potentially ciphered in English, due to, what look to be stiking similarities between the alphabetic character frequencies of the notes:

and the frequencies of characters in English:

If anyone else wants to have a play here is my (rough) transcripts and an ODS with some frequencies:

I'll update here if I find anything interesting. Lots of patterns repeated in this text!

NP. Is there "beer for bug reports" too?

double122on How ~75% of PirateBay traffic is seeded by 100 people driven by profit

Articles like these make me wish HN had a TL;DR option. Something like:

How ~75% of PirateBay traffic is seeded by 100 people driven by profit

"Seeders put links in their content requesting that you visit their Adsense driven site" Click to read more...

Nice idea for my next hacking project maybe.

double122on A Standard for the Transmission of IP Datagrams on Avian Carriers

There was a question about this in a formal exam, in my first year at uni:

"RFC 1149 was release on 01/04/90, but what was it about?"

Some lecturers do have a sense of humour!

double122on I always forget the argument order of the `ln -s` command

Could you maybe add:

alias ln='ln -s'

to your .bashrc? A quick test of this in my terminal and the alias takes precedent over the ln command. Although, I guess it'd be worth doing a few tests to make certain!

double122on Why I feel like a fraud

I sympathise entirely with this post. I too didn't realise that it was a common way of thinking until I saw this a while back:
