determining the ‘legitimacy’/’reliability’ of a domain

I’ve recently been asked by several people to investigate websites (especially e-commerce ones) for reliability/legitimateness. Thought someone else may find my process useful, and/or have some ideas on how to improve it ? So here goes: Pop a terminal window (I’m on a Mac, so I open Terminal – feel free to use your terminal …

My original search had been along the lines of: | inputlookup mylookup| stats count by type| fields – count| transpose| fields – column Which was great … until my list grew …

a poor user’s guide to accelerating data models in splunk

Data Models are one of the major underpinnings of Splunk’s power and flexibility. They’re the only way to benefit from the powerful pivot command, for example. They underlie Splunk Enterprise Security (probably the biggest “non-core” use of Splunk amongst all their customers). Key to achieving peak performance from Splunk Data Models, though, is that they …

libraries should be print-on-demand centers – especially for old/unusual works

Want to reinvigorate old texts and library patronage? Turn libraries into print-on-demand book “publishers” for works in the public domain and/or which aren’t under copyright in the current country and/or some kind of library version of CCLI churches use for music! This idea came to me after reading this blog post from the Internet Archive …

comparing unique anagrams?

How useful would determining similarity of words by their unique anagrams be? For example: “ROBERT” uniquely anagrams to “BEORT”; “BOBBY” and “BOOBY” both uniquely anagram to “BOY”. Is there already a comparison algorithm that uses something like this? What potentially “interesting” discoveries might be made about vocabularical choices if you analyzed text corpora with this …

splunk: match a field’s value in another field

Had a Splunk use-case present itself today on needing to determine if the value of a field was found in another – specifically, it’s about deciding if a lookup table’s category name for a network endpoint is “the same” as the dest_category assigned by a Forescout CounterACT appliance. We have “customer validated” (and we all …
