TODO what does this Chinese forum track? New registrations? Their focus seems to be domain name speculation
Some of the threads contain domain dumps. We haven't yet seen a scrapable URL pattern, but their data goes way back and did have various hits. The forum seems to have started in 2006: club.domain.cn/forum.php?mod=forumdisplay&fid=41&page=10127
club.domain.cn/forum.php?mod=viewthread&tid=241704 "【国际域名拟删除列表】2007年06月16日" is the earliest list we could find. It is an expired domain list.
Some hits:
pastebin.com/CTXnhjeS dated mega early on Sep 30th, 2012 by CYBERTAZIEX.
This source was found by Oleg Shakirov.
Holy fuck the type of data source that we get in this area of work!
This pastebin contained a few new hits, in addition to some pre-existing ones. Most of the hits them seem to be linked to the IP 72.34.53.174, which presumably is a major part of the fingerprint found by CYBERTAZIEX, though unsurprisingly methodology is unclear. As documented, the domains appear to be linked to a "Condor hosting" provider, but it is hard to find any information about it online.
From the title, it would seem that someone hacked into Condor and defaced all of its sites, including unknowingly some CIA ones which is LOL.
Ciro Santilli checked every single non-subdomain domain in the list.
Other files under the same account: pastebin.com/u/cybertaziex did not seem of interest.
The author's real name appears to be Deni Suwandi: twitter.com/denz_999 from Indonesia, but all accounts appear to be inactive, otherwise we'd ping him to ask for more info about the list.
www.zone-h.com lists some of the domains. They also seem to have intended to have snapshots of the defaces but we can't see them which is sad:
alljohnny.com had a hit: ipinf.ru/domains/alljohnny.com/, and so Ciro started looking around... and a good number of other things have hits.
Not all of them, definitely less data than viewdns.info.
But they do reverse IP, and they show which nearby reverse IPs have hits on the same page, for free, which is great!
Shame their ordering is purely alphabetical, doesn't properly order the IPs so it is a bit of a pain, but we can handle it.
OMG, Russians!!!
The data here had a little bit of non-overlap from other sources. 4 new confirmed hits were found, plus 4 possible others that were left as candidates.
In this section we document the outcomes of more detailed inspection of both the communication mechanisms (JavaScript, JAR, swf) and HTML that might help to better fingerprint the websites.
There are four main types of communication mechanisms found:
  • There is also one known instance where a .zip extension was used! web.archive.org/web/20131101104829*/http://plugged-into-news.net/weatherbug.zip as:
    <applet codebase="/web/20101229222144oe_/http://plugged-into-news.net/" archive="/web/20101229222144oe_/http://plugged-into-news.net/weatherbug.zip"
    JAR is the most common comms, and one of the most distinctive, making it a great fingerprint.
    Several of the JAR files are named something like either:
    as if to pose as Internet speed testing tools? The wonderful subtleties of the late 2000s Internet are a bit over our heads.
    All JARs are directly under root, not in subdirectories, and the basename usually consist of one word, though sometimes two camel cased.
  • JavaScript file. There are two subtypes:
    • JavaScript with SHAs. Rare. Likely older. Way more fingerprintable.
    • JavaScript without SHAs. They have all been obfuscated slightly different and compressed. But the file sizes are all very similar from 8kB to 10kB, and they all look similar, so visually it is very easy to detect a match with good likelyhood.
  • Adobe Flash swf file. In all instances found so far, the name of the SWF matches the name of the second level domain exactly, e.g.:
    http://tee-shot.net/tee-shot.swf
    While this is somewhat of a fingerprint, it is worth noting that is was a relatively commonly used pattern. But it is also the rarest of the mechanisms. This is a at a dissonance with the rest of the web, which circa 2010 already had way more SWF than JAR apparently.
    Some of the SWF websites have archives for empty /servlet pages:
    ./bailsnboots.com/20110201234509/servlet/teammate/index.html
    ./currentcommunique.com/20110130162713/servlet/summer/index.html
    ./mynepalnews.com/20110204095758/servlet/SnoopServlet/index.html
    ./mynepalnews.com/20110204095403/servlet/release/index.html
    ./www.hassannews.net/20101230175421/servlet/jordan/index.html
    ./zerosandonesnews.com/20110209084339/servlet/technews/index.html
    which makes us think that it is a part of the SWF system.
  • CGI comms
These have short single word names with some meaning linked to their website.
Because the communication mechanisms are so crucial, they tend to be less varied, and serve as very good fingerprints. It is not ludicrous, e.g. identical files, but one look at a few and you will know the others.
The Quadratic Integrate-and-Fire (QIF) model is a mathematical representation used to describe the behavior of a neuron. It builds upon the simpler Integrate-and-Fire (IF) model by incorporating quadratic nonlinearity to more accurately represent the dynamics of action potentials (spikes) in neurons.
The term "small control property" is often discussed in the context of functional analysis and operator theory. It pertains to a specific characteristic of certain types of Banach spaces or functional spaces. A space is said to have the small control property if, roughly speaking, every bounded linear operator from this space into a Hilbert space can be approximated by finite-rank operators in a certain way.
Stephen Childress is likely a reference to a specific individual, but without more context, it's difficult to determine exactly who you are referring to as there are multiple individuals with that name.
Streamline diffusion is a concept often used in fluid dynamics and related fields to describe the movement of particles or substances within a fluid flow. It refers to the process by which particles or molecules distribute themselves along the streamlines of a flow. In more specific terms, streamline diffusion is typically associated with the way substances diffuse within a moving fluid, influenced by the flow's velocity and direction.
Distributed data processing refers to the practice of managing and analyzing large volumes of data across multiple machines or nodes in a network. This approach divides the data and processing tasks among several computing units, which can work concurrently, improving efficiency and speeding up processing times compared to traditional, centralized data processing methods. Key features of distributed data processing include: 1. **Scalability**: Systems can easily scale horizontally by adding more nodes to handle larger datasets or increased workloads.
The International Symposium on Symbolic and Algebraic Computation (ISSAC) is a prestigious academic conference that focuses on research and developments in the fields of symbolic and algebraic computation. The symposium serves as a platform for researchers and practitioners to present their work, share ideas, and discuss advancements in algorithms, software, and applications related to symbolic computation, algebraic mathematics, and related areas.
Transversality conditions are mathematical constraints used primarily in the field of optimal control theory and calculus of variations. They ensure that solutions to optimization problems—particularly those involving differential equations—are well-defined and meet certain criteria at the endpoints of the optimization interval. In a typical setting, when optimizing a functional that involves a continuous state variable over a specified interval, the transversality condition helps to determine the behavior of the control (or path) at the boundary points.

Pinned article: Introduction to the OurBigBook Project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 2.
    You can publish local OurBigBook lightweight markup files to either https://OurBigBook.com or as a static website
