The Week in Internet News: ISPs Sue Maine Over New Privacy Law
Protesting privacy: Four ISP trade groups are suing the state of Maine for a privacy law that goes into effect this year, Ars Technica reports. Among other things, the law supposedly violates ISP free speech rights because it limits their ability to advertise to their customers and to offer discounts in exchange for customers’ personal information. The Maine law requires ISPs to get customers’ opt-in consent before using or sharing sensitive data.
DSL over fiber: The California Advanced Services Fund, a program launched in 2008 to connect all Californians to broadband, was an early success, but recent actions in the state legislature have encouraged slow speeds of 6 Mbps and eliminated the fund’s ability to serve public housing already served by slow DSL service, the EFF says in a blog post. “By establishing an abysmally low standard based on DSL technology that made its debut more than a decade ago, the state’s regulator is forced to conclude that basically everyone has useful broadband access today,” the EFF says. “This has kept the state from closing the digital divide.”

Cloudflare’s Gen X: Servers for an Accelerated Future
“Every server can run every service.”
We designed and built Cloudflare’s network to be able to grow capacity quickly and inexpensively; to allow every server, in every city, to run every service; and to allow us to shift customers and traffic across our network efficiently. We deploy standard, commodity hardware, and our product developers and customers do not need to worry about the underlying servers. Our software automatically manages the deployment and execution of our developers’ code and our customers’ code across our network. Since we manage the execution and prioritization of code running across our network, we are both able to optimize the performance of our highest tier customers and effectively leverage idle capacity across our network.
An alternative approach might have been to run several fragmented networks with specialized servers designed to run specific features, such as the Firewall, DDoS protection or Workers. However, we believe that approach would have resulted in wasted idle resources and given us less flexibility to build new software or adopt the newest available hardware. And a single optimization target means we can provide security and performance at the same time.

Automation Story: Add a Web UI
Imagine you followed the steps taken by Anne Baretta and stored network inventory into a database. What could you do with that information (apart from creating reports)? How about adding a web UI to help less-skilled network operators perform automated tasks?
Notes
- While we won’t tell you how to build a web UI in our network automation course, we will tell you how to build a system out of numerous components (and what components you might need).

20 years of maintaining an open source program
It’s been almost 10 years since my previous post about
this. And 20 years since 2000-02-24, which is when arping 0.1
was released. It was a 208 line C file, with a hand made Makefile.
As of today when Arping 2.21 is overdue to be released, the code in
.c and .h files (excluding tests) is 3863 lines, and it uses the
amazing autotools framework for analyzing dependencies.
I’ve recently had the displeasure of working with cmake, which is
just the worst. Why anyone would think cmake is even remotely
acceptable I’ll never understand.
But the Arping story continues. It isn’t getting many new major features. Still, since the last post there’s been 205 commits, and 10 releases.
Things like:
- Change from
gettimeofday()toclock_gettime(), when available. More info about that in this blog post. - Don’t check for
uid=0and stop. Capabilities can come in other ways - Change from
poll()toselect()to work around bug in MacOS X - Use nice and modern
getifaddrs()to resolve interfaces - Update documentation
- Improve error messages
- Update author email address
- Fix warnings and general code cleanup
- Used coverity to find and fix suspicious code
- Add some more stats to output
- Continue reading
