  • Schneier on Security: Interview with a Nigerian Internet Scammer – "We had something called the recovery approach. A few months after the original scam, we would approach the victim again, this time pretending to be from the FBI, or the Nigerian Authorities. The email would tell the victim that we had caught a scammer and had found all of the details of the original scam, and that the money could be recovered. Of course there would be fees involved as well. Victims would often pay up again to try and get their money back."
  • xkcd – Frequency of Strip Versions of Various Games – n = Google hits for "strip <game name>" / Google hits for "<game name>"
  • PeteSearch: How to split up the US – Visualization of social network clusters in the US. "information by location, with connections drawn between places that share friends. For example, a lot of people in LA have friends in San Francisco, so there's a line between them.

    Looking at the network of US cities, it's been remarkable to see how groups of them form clusters, with strong connections locally but few contacts outside the cluster. For example Columbus, OH and Charleston WV are nearby as the crow flies, but share few connections, with Columbus clearly part of the North, and Charleston tied to the South."

  • Redis: Lightweight key/value Store That Goes the Extra Mile | Linux Magazine – Sort of like memcache. "Calling redis a key/value store doesn’t quite due it justice. It’s better thought of as a “data structures” server that supports several native data types and operations on them. That’s pretty much how creator Salvatore Sanfilippo (known as antirez) describes it in the documentation. Let’s dig in and see how it works."
  • Op-Ed Contributor – Microsoft’s Creative Destruction – NYTimes.com – Unlike other companies, Microsoft never developed a true system for innovation. Some of my former colleagues argue that it actually developed a system to thwart innovation. Despite having one of the largest and best corporate laboratories in the world, and the luxury of not one but three chief technology officers, the company routinely manages to frustrate the efforts of its visionary thinkers.

  • Leonardo da Vinci’s Resume Explains Why He’s The Renaissance Man For the Job – Davinci – Gizmodo – At one time in history, even da Vinci himself had to pen a resume to explain why he was a qualified applicant. Here's a translation of his letter to the Duke of Milan, delineating his many talents and abilities. "Most Illustrious Lord, Having now sufficiently considered the specimens of all those who proclaim themselves skilled contrivers of instruments of war, and that the invention and operation of the said instruments are nothing different from those in common use: I shall endeavor, without prejudice to any one else, to explain myself to your Excellency, showing your Lordship my secret, and then offering them to your best pleasure and approbation to work with effect at opportune moments on all those things which, in part, shall be briefly noted below..The document, written when da Vinci was 30, is actually more of a cover letter than a resume; he leaves out many of his artistic achievements and instead focuses on what he can provide for the Duke in technologies of war.
  • jsMath: jsMath Home Page – The jsMath package provides a method of including mathematics in HTML pages that works across multiple browsers under Windows, Macintosh OS X, Linux and other flavors of unix. It overcomes a number of the shortcomings of the traditional method of using images to represent mathematics: jsMath uses native fonts, so they resize when you change the size of the text in your browser, they print at the full resolution of your printer, and you don't have to wait for dozens of images to be downloaded in order to see the mathematics in a web page. There are also advantages for web-page authors, as there is no need to preprocess your web pages to generate any images, and the mathematics is entered in TeX form, so it is easy to create and maintain your web pages. Although it works best with the TeX fonts installed, jsMath will fall back on a collection of image-based fonts (which can still be scaled or printed at high resolution) or unicode fonts when the TeX fonts are not available.
  • Josh on the Web » Blog Archive » Abusing the Cache: Tracking Users without Cookies – To track a user I make use of three URLs: the container, which can be any website; a shim file, which contains a unique code; and a tracking page, which stores (and in this case displays) requests. The trick lies in making the browser cache the shim file indefinitely. When the file is requested for the first – and only – time a unique identifier is embedded in the page. The shim embeds the tracking page, passing it the unique ID every time it is loaded. See the source code.

    One neat thing about this method is that JavaScript is not strictly required. It is only used to pass the message and referrer to the tracker. It would probably be possible to replace the iframes with CSS and images to gain JS-free HTTP referrer logging but would lose the ability to store messages so easily.

  • Panopticlick – Your browser fingerprint appears to be unique among the 342,943 tested so far.

    Pydroid is a simple toolkit for automating and scripting repetitive tasks, especially those involving a GUI, with Python. It includes functions for controlling the mouse and keyboard, finding colors and bitmaps on-screen, as well as displaying cross-platform alerts.
    Why use Pydroid?

    * Testing a GUI application for bugs and edge cases
    o You might think your app is stable, but what happens if you press that button 5000 times?
    * Automating games
    o Writing a script to beat that crappy flash game can be so much more gratifying than spending hours playing it yourself.
    * Freaking out friends and family
    o Well maybe this isn't really a practical use, but…

  • How informative is Twitter? » SemanticHacker Blog – "We undertook a small study to characterize the different types of messages that can be found on Twitter. We downloaded a sample of tweets over a two-week period using the Twitter streaming API. This resulted in a corpus of 8.9 million messages (”tweets”) posted by 2.6 million unique users. About 2.7 million of these tweets, or 31%, were replies to a tweet posted by another user, while half a million (6%) were retweets. Almost 2 million (22%) of the messages contained a URL."

  • How to convert email addresses into name, age, ethnicity, sexual orientation – This is so Meta – "Save your email list as a CSV file (just comma separate those email addresses). Upload this file to your facebook account as if you wanted to add them as friends. Voila, facebook will give you all the profiles of all those users (in my test, about 80% of my email lists have facebook profiles). Now, click through each profile, and because of the new default facebook settings, which makes all information public, about 95% of the user info is available for you to harvest."

  • PeteSearch: How to find user information from an email address – FindByEmail code released as open-source. You pass it an email address, and it queries 11 different public APIs to discover what information those services have on the user with that email address.
  • Measuring Measures: Beyond PageRank: Learning with Content and Networks – Conclusion: learning based on content and network data is the current state of the art There is a great paper and talk about personalization in Google News they use content for this purpose, and then user click streams to provide personalization, i.e. recommend specific articles within each topical cluster. The issue is content filtering is typically (as we say in research) "way harder." Suppose you have a social graph, a bunch of documents, and you know that some users in the social graph like some documents, and you want to recommend other documents that you think they will like. Using approaches based on Networks, you might consider clustering users based on co-visitaion (they have co-liked some of the documents). This scales great, and it internationalizes great. If you start extracting features from the documents themselves, then what you build for English may not work as well for the Chinese market. In addition, there is far more data in the text than there is in the social graph
  • mikemaccana’s python-docx at master – GitHub – MIT-licensed Python library to read/write Microsoft Word docx format files. "The docx module reads and writes Microsoft Office Word 2007 docx files. These are referred to as 'WordML', 'Office Open XML' and 'Open XML' by Microsoft. They can be opened in Microsoft Office 2007, Microsoft Mac Office 2008, OpenOffice.org 2.2, and Apple iWork 08. The module was created when I was looking for a Python support for MS Word .doc files, but could only find various hacks involving COM automation, calling .net or Java, or automating OpenOffice or MS Office."

  • New Twitter Research: Men Follow Men and Nobody Tweets – Conversation Starter – HarvardBusiness.org – "Although men and women follow a similar number of Twitter users, men have 15% more followers than women. Men also have more reciprocated relationships, in which two users follow each other. This "follower split" suggests that women are driven less by followers than men, or have more stringent thresholds for reciprocating relationships. This is intriguing, especially given that females hold a slight majority on Twitter: we found that men comprise 45% of Twitter users, while women represent 55%."
  • Shirky: Power Laws, Weblogs, and Inequality – 2003 article on popularity / traffic on blogs, which was then the latest emerging social media format. "Once a power law distribution exists, it can take on a certain amount of homeostasis, the tendency of a system to retain its form even against external pressures. Is the weblog world such a system? Are there people who are as talented or deserving as the current stars, but who are not getting anything like the traffic? Doubtless. Will this problem get worse in the future? Yes. "

"These new large datacenters are quite different from traditional hosting facilities of earlier times and cannot be viewed simply as a collection of co-located servers. Large portions of the hardware and software resources in these facilities must work in concert to efficiently deliver good levels of Internet service performance, something that can only be achieved by a holistic approach to their design and deployment. In other words, we must treat the datacenter itself as one massive warehouse-scale computer (WSC). We describe the architecture of WSCs, the main factors influencing their design, operation, and cost structure, and the characteristics of their software base."

  • When Korean Culture Flourished – WSJ.com – In the geography of the Metropolitan Museum of Art, the gallery devoted to Korea acts as a sort of land bridge between China and South Asia that all too often serves as passage rather than destination. The first in a series of shows to be held over the next 10 to 15 years, "Art of the Korean Renaissance, 1400-1600" may change this. With only 47 objects(!), the exhibition explores a fertile 200-year period in Korea's cultural history, revealing as much through its choice of works as it does through the order in which it displays them. The show's modest size makes the point that, sadly, little has survived from this period, when the Joseon — or Fresh Dawn — dynasty (1392-1910) united the Korean peninsula militarily, established Confucianism as the national ideology and introduced a phonetic alphabet.

  • Skew, The Frontend Engineer’s Misery @ Irrational Exuberance – For mashups and the like, the distinction between a FE engineer and web dev is rather small in terms of technical skills; they are both using the same skillset, they are both interacting with APIs, and so on. However, there are important distinctions between the two: 1. web developers tend to move in small groups or as individuals, whereas fe engineers work in larger groups, 2. web developers tend to design a product on top of an existing backend service (api, etc), while fe engineers are usually working in parallel with the backend being developed.
