- Reality Bytes — We make things because that’s how we understand. We make things because that’s how we pass them on, and because everything we have was passed on to us as a made object. We make things in digital humanities because that’s how we interpret and conserve our inheritance. Because that’s how we can make it all anew. Librarians, preservation, digital humanities, and the relationship between digital and physical. Existential threats don’t scare us. We’re librarians.
- Kickstarter Stats — as Andy Baio said, it’s the one Kickstarter feature that competitors won’t be rushing to emulate. Clever way to emphasize their early lead.
- ICANN is Wrong (Dave Winer) — Dave is right to ask why nobody’s questioning the lack of public registration in the new domains. You can understand why, say, the Australia-New Zealand bank wouldn’t let Joe Random register in .anz, but Amazon are proposing to keep domains like .shop, .music, .app for their own products. See all the bidders for the new gTLDs on the ICANN web site.
- The Art of GPS (Daily Mail) — beautiful visualizations of uncommon things, such as the flights that dead bodies make when they’re being repatriated to their home states. Personally, I think they tend too much to the “pretty” and insufficient to the “informative” or “revealing”, but then I’m notorious for being too revealing and insufficiently informative.

Spin up Python-friendly services with 0 lines of code
Twisted is a framework for writing, testing, and deploying event-driven clients and servers in Python. In my previous Twisted blog post, we explored an architectural overview of Twisted and examples of simple TCP, UDP, SSL, and HTTP echo servers.
While Twisted makes it easy to build servers in just a few lines of Python, you can actually use Twisted to spin up servers with 0 lines of code!
We can accomplish this with
twistd (pronounced twist-dee), a command line utility that ships with Twisted for deploying your Twisted applications. In addition to providing a standardized deployment interface for common production features like daemonization, logging, and authentication,
twistd can use Twisted’s plugin architecture to run flexible servers for a variety of protocols. Here are some examples:
twistd web --port 8000 --path .
Run an HTTP server on port 8000, serving both static and dynamic content out of
the current working directory. Visit
http://localhost:8000 to see the directory listing:
Learn to build event-driven client and server applications
I want to build a web server, a mail server, a BitTorrent client, a DNS server, or an IRC bot—clients and servers for a custom protocol in Python. And I want them to be cross-platform, RFC-compliant, testable, and deployable in a standardized fashion. What library should I use?
Twisted is a “batteries included” networking engine for writing, testing, and deploying event-driven clients and servers in Python. It comes with off-the-shelf support for popular networking protocols like HTTP, IMAP, IRC, SMTP, POP3, IMAP, DNS, FTP, and more.
To see just how easy it is to write networking services using Twisted, let’s run and discuss a simple Twisted TCP echo server:
from twisted.internet import protocol, reactor
def dataReceived(self, data):
def buildProtocol(self, addr):
With Twisted installed, if we save this code to echoserver.py and run it with python echoserver.py, clients can now connect to the service on port 8000, send it data, and get back their echoed results. Read more…

A look back at "Unix Power Tools," "DNS and Bind," and other O'Reilly titles.
Tim O'Reilly: "It's amazing to me how books I first published more than 20 years ago are still creating value for readers."
- Mozilla’s Secure Coding Guidelines — the Mozilla recommendations for web application security. See also OWASP, Google’s Browser Security Handbook and Google’s course.
- How Fast-Flux Service Networks Operate — explanation of a technique used by botnets and other malware hordes to make it hard to figure out on which machines the services are actually running. For an example, see The Inside Story of the Kelihos Botnet Takedown.

China Snaffling Facebook Stock, DNS Douchebaggery, Corporate Whores, and Comic Relief
- China Wants to Buy Facebook (Forbes) — Beijing approached a fund that buys stock from former Facebook employees to see if it could assemble a stake large enough “to matter.” This has implications for Facebook entering China. Chief Operating Officer Sheryl Sandberg is reportedly “wary about the compromises Facebook would have to make to do business there.” If she loses her argument with Zuckerberg and Facebook enters China, the company will eventually be subject to demands to censor its sites, those both inside and outside China. That’s apparently why the Chinese want to own a big stake in Facebook. They are, in short, looking for control in the long run. No other explanation is consistent with the Party’s other media and “educational” initiatives. Again the world’s most desirable emerging market is fraught for those who would enter it.
- Cisco Helping China Build Surveillance (WSJ, subscription probably needed) — Western companies including Cisco Systems Inc. are poised to help build an ambitious new surveillance project in China—a citywide network of as many as 500,000 cameras that officials say will prevent crime but that human-rights advocates warn could target political dissent. Check out the mealy-mouthed weasel from HP: “We take them at their word as to the usage.” He added, “It’s not my job to really understand what they’re going to use it for. Our job is to respond to the bid that they’ve made.” (a) buyers don’t bid, vendors bid; (b) you’re a piss-poor vendor if you don’t understand what the client hopes to achieve; (c) really, maintaining plausible denial is the best way to preserve your brand’s integrity? Hewlett and Packard are turning in their graves, the heat given off from which could be detected by sensors, routed through Cisco boxes and displayed on HP terminals.
- US Claims .net and .com In Their Jurisdiction — The US Immigration and Customs Enforcement agency (ICE) wants to take down web sites that use the .com and .net top level domains (TLD) regardless of whether their servers are based in the US. Not only do DNS interventions like this not stop the copying, they’re the thin end of the political wedge into yet another piece of critical Internet infrastructure. Who woke up this morning and thought, “I want a copyright rentacop to decide which websites I can see”? The generative power of the Internet is eroded with every misguided meddling such as this.
- SVK Launches — BERG London finally launch their excellent comic. “Comic?” you ask. Noted science future awesome Warren Ellis wrote it, and it features some clever augmented reality hardware. I have one, and I am happy. You can be too, for only ten pounds plus shipping.

Search Tips, Web Parsing, DNS Blacklists, Complex Machines
- Hidden Features of Google (StackExchange) — rather than Google’s list of search features, here are the features that real (sophisticated) users find useful. My new favourite: the ~ operator for approximate searching. (via Hacker News)
- Natural Language Parsing for the Web — JSON API to the Stanford Natural Language Parser. I wonder why the API to the library isn’t an open source library, given the Stanford parser is GPLv2. It’d be super-cool to have this as an EC2 instance, Ubuntu package, or Chef recipe so it’s trivial to add to an existing hosted project.
- Taking Back the DNS (Paul Vixie) — defining a spec whereby you can subscribe to blacklists for DNS, as Most new domain names are malicious.

The U.S. Department of Commerce, which is
ICANN’s publicly accountable overseer, announced the most important
decision affecting ICANN since its founding: the U.S. government will
give up its role as overseer
and make ICANN independent.
