Rforecastio Package Update (1.1.0)

I’ve bumped up the version number of `Rforecastio` ([github](https://github.com/hrbrmstr/Rforecastio)) to `1.1.0`. The new features are: – removing the SSL certificate bypass check (it doesn’t need it anymore) – using `plyr` for easier conversion of JSON-\>data frame – adding in a new `daily` forecast data frame – roxygen2 inline documentation library(Rforecastio) library(ggplot2) library(plyr)   # NEVER… Continue reading →

Moving From system() calls to Rcpp Interfaces

Over on the [Data Driven Security Blog](http://datadrivensecurity.info/blog/posts/2014/Apr/making-better-dns-txt-record-lookups-with-rcpp/) there’s a post on how to use `Rcpp` to interface with an external library (in this case `ldns` for DNS lookups). It builds on [another post](http://datadrivensecurity.info/blog/posts/2014/Apr/firewall-busting-asn-lookups/) which uses `system()` to make a call to `dig` to lookup DNS `TXT` records. The core code is below and at both… Continue reading →

The original Python code is crufty and a mess mostly due to the intermittent attention to it, wanting to reduce dependencies and hacking vs programming. I’ve been wanting to do… Continue reading →

nizdos – Nest Thermometer Notifications And Data Logging In Python

I’ve had a Nest thermometer for a while now and it’s been an overall positive experience. It’s given me more visibility into our heating/cooling system usage, patterns and preferences; plus, it actually saved us money last winter. We try to avoid running the A/C during the summer, and it would have been really helpful if… Continue reading →

Reverse IP Address Lookups With R (From Simple To Bulk/Asynchronous)

R lacks some of the more “utilitarian” features found in other scripting languages that were/are more geared—at least initially—towards systems administration. One of the most frustrating missing pieces for security data scientists is the lack of ability to perform basic IP address manipulations, including reverse DNS resolution (even though it has nsl() which is just… Continue reading →
