I listen to @NPR throughout the day (on most days) and a story on Ohmconnect piqued my interest (it aired 5 days prior to this post). The TLDR on Ohmconnect is that it ostensibly helps you save energy by making you more aware of consumption and can be enabled to control various bits of IoT… Continue reading

This is not cool.
First it was OpenDNS selling their souls (and, [y]our data) to Cisco (whom I don’t trust at all with my data). Now, it’s Dyn — — doing something even worse (purely my own opinion). I’m currently evaluating offerings by [FoolDNS](http://www.fooldns.com/fooldns-community/english-version/) & [GreenTeam](http://members.greentm.co.uk/) as alternatives and I’ll post updates as I review & test them. I’m… Continue reading
Slaying CIDR Orcs with Triebeard (a.k.a. fast trie-based ‘IPv4-in-CIDR’ lookups in R)
The insanely productive elf-lord, @quominus put together a small package ([`triebeard`](https://github.com/ironholds/triebeard)) that exposes an API for [radix/prefix tries](https://en.wikipedia.org/wiki/Trie) at both the R and Rcpp levels. I know he had some personal needs for this and we both kinda need these to augment some functions in our `iptools` package. Despite `triebeard` having both a vignette and… Continue reading
Clandestine DNS lookups with gdns
Google recently [announced](https://developers.google.com/speed/public-dns/docs/dns-over-https) their DNS-over-HTTPS API, which _”enhances privacy and security between a client and a recursive resolver, and complements DNSSEC to provide end-to-end authenticated DNS lookups”_. The REST API they provided was pretty simple to [wrap into a package](https://github.com/hrbrmstr/gdns) and I tossed in some [SPF](http://www.openspf.org/SPF_Record_Syntax) functions that I had lying around to bulk it… Continue reading
iptools 0.4.0 released into the wild (i.e. is hitting the CRAN mirrors today)
The [`iptools` package](https://github.com/hrbrmstr/iptools)—a toolkit for manipulating, validating and testing IP addresses and ranges, along with datasets relating to IP addresses—is flying through the internets and hitting a CRAN mirror near you, soon. ### What’s fixed? [Tim Smith](https://github.com/tdsmith) fixed [a bug](https://github.com/hrbrmstr/iptools/issues/26) in `ip_in_range()` that occurred when the netmask was `/32` (thanks, Tim!). ### What’s new? The… Continue reading
iptools 0.3.0 (“Violet Packet”) Now on CRAN with Windows Support!
`iptools` is a set of tools for working with IP addresses. Not just work, but work _fast_. It’s backed by `Rcpp` and now uses the [AsioHeaders](http://dirk.eddelbuettel.com/blog/2016/01/07/#asioheaders_1.11.0-1) package by Dirk Eddelbuettel, which means it no longer needs to _link_ against the monolithic Boost libraries and *works on Windows*! What can you do with it? One thing… Continue reading
Paths To Discovery: Mapping Your Home Network
Gone are the days when one had a single computer plugged directly into a modem (cable, DSL or good ol’ Hayes). Even the days when there were just one or two computers connected via wires or invisible multi-gigahertz waves passing through the air are in the long gone by. Today (as you’ll see in the… Continue reading
Beware of sideloading f.lux for iOS from files obtained on sharing/torrent sites
Apple made the @justgetflux folks remove their [iOS sideloaded app](https://justgetflux.com/sideload/) due to the use of private APIs (which are a violation of the Apple Developer agreement). The ZIP archive has been pulled from their site (and it really has, too). This “sideloading”—i.e. installing directly to your device after compiling it from source—_was_ an interesting way… Continue reading
