Bufferbloat and the Ski Shop

Bufferbloat is undesirable latency caused by a router buffering too much data. It makes your kids say, “The Internet is slow today, Daddy”. It’s caused by routers and other network equipment buffering (accepting for delivery) more data than can be delivered in a timely way. Bufferbloat causes much of the poor performance and human pain

More magma…

We have been planning a trip to Iceland (mostly to see the aurora) next year. I am now looking into tours that go near the volcano at Bárðarbunga and Holuhraun as well. I think that land tours (I would love to stand next to the lava front) are out of the question, since the authorities

A Memorization Tip

I have given out this tip in past years to people in Revels North who’re preparing for the Christmas Revels show… I found this trick for memorization in a wonderful book, Don’t Shoot the Dog, The new art of teaching and training, by Karen Pryor. It talks about modifying behavior — yours and others. (One

Gettin’ my magma jollies!

I’ve been following Rei, a blogger from Iceland, who is reporting on the Bárðarbunga/Holuhraun volcano as it continues to erupt. It’s way more impressive/scary than I originally thought. It’s huge, with fresh lava covering 37 square km, or about 2/3 the size of Manhattan, and the magma fountains are shooting 300 feet or more in

CeroWrt 3.10.50-1 Field Report

Comments on the CeroWrt 3.10.50-1 build that I installed on my WNDR3700v2 primary router: Seemed to install and configure properly (I retrieved the updated version with the lighthttpd fix) I used a local copy of config-cerowrt.sh (from https://github.com/richb-hanover/CeroWrtScripts#config-cerowrtsh) to configure the router to have my own DSL user/pw, SSID names, etc. mDNS seems to work

speedof.me

Doc Searls mentioned in passing that he uses a new speed test website. I checked it out, and it was very cool… www.speedof.me is an all-HTML5 website that seems to make accurate measurements of the up and download speeds of your internet connection. It’s also very attractive, and the real-time plots of the speed show

New CeroWrt Router scripts

I posted a set of scripts that people can use to test, configure and debug their CeroWrt router installations. CeroWrt router firmware is a test bed for learning about and eliminating bufferbloat. The scripts are available on Github at https://github.com/richb-hanover/CeroWrtScripts. They include: betterspeedtest.sh – a script that emulates the famous (but limited) speedtest.net. This script

Net Neutrality & Whitehouse.gov petition

There’s a Whitehouse.gov petition posted about Net Neutrality. It’s a little bit of a rant, but I agree with its punchline: No bandwidth modifications of information based on content or its source. This relates to a comment from Philip Greenspun’s blog (How many times do we have to pay for the same internet service?) If

LibreSSL fork of OpenSSL

A small team of well-known developers from the OpenBSD team is working on a fork of OpenSSL, to be named LibreSSL. This group is going through the OpenSSL source code base and removing old/ancient distributions, reformatting the code to KNF (Kernel Normal Format), removing dead code, fixing bugs and improving the package documentation. They’re aided
