- Mar 08CIRT.net | Suspicion Breeds Confidence
Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items, including over 6100 potentially dangerous files/CGIs, checks for outdated versions of over 950 servers, and version specific problems on over 260 servers. It also checks for server configuration items such as the presence of multiple index files, HTTP server options, and will attempt to identify installed web servers and software. Scan items and plugins are frequently updated and can be automatically updated.
Nikto is not designed as an overly stealthy tool. It will test a web server in the quickest time possible, and is fairly obvious in log files. However, there is support for LibWhisker's anti-IDS methods in case you want to give it a try (or test your IDS system). - Mar 04The Three Giants of Linux | Linux Magazine
According to DistroWatch, sixty-six distributions have been created from Slackware. Red Hat Linux has spawned around forty directly (with another eighty or so coming from Fedora), while grand daddy Debian makes it two hundred and fifty! At the end of the day, the majority of Linux distributions which exist today are at some point a derivative of one of these three.
These three distributions really couldn’t get much more different. Of course the core is the same in each; a Linux kernel, GNU user-land as well as various desktops and applications. Aside from the required similarities, how do these distributions differ? As you’ll see, each one encompasses a unique perspective, which shows just how important diversity is!
- Mar 04The eye of the beholder: Wavelet JPEG 2000 vs. DCT MPEG-2 | The JPEG 2000 compression format offers more bang for less bucks
Conclusion
JPEG 2000 is a clear winner over MPEG-2 for many mastering uses, but there are other high-quality compression alternatives that are not wavelet-based, which can also outperform MPEG-2. AVC-Intra is an example. The current debate between JPEG 2000 and AVC-Intra is complex.Broadly speaking, both easily outperform MPEG-2, but each has its own characteristics. There are arguments about the subjective perception of which performs better depending on the compression levels used and the kind of subject material. For example, at medium bit rates, do you prefer less detail with no blocks (JPEG 2000), or more detail with some blocking (AVC-Intra) as bit rates drop further?
Whatever your viewpoint, as mezzanine intermediate formats, supporters of both JPEG 2000 and AVC-Intra have argued that there are quality benefits, especially if your final delivery format is also DCT-based. In mastering applications, there are clear benefits of using JPEG 2000 compared with DCT-based MPEG-2. If quality is your business driver, JPEG 2000 offers more bang for less bucks because of less bits and less blocks.
- Mar 02VIVO: Cornell Research & Scholarship
VIVO (not an acronym) brings together in one site publicly available information on the people, departments, graduate fields, facilities, and other resources that collectively make up the research and scholarship environment in all disciplines at Cornell.
Search VIVO for information about faculty, departments and research units, undergraduate majors, graduate fields, courses, research services and facilities --- anything related to academic and research pursuits at Cornell.
The VIVO project was initiated and resides in the Cornell University Library, with support from the Office of the Provost. Technology development and disciplinary content entry are directed by appropriate subject experts in the Library, who are also part of the VIVO project team.

- Feb 28Textbook Publishers Win Court Ruling Against File-Sharing Web Site - Technology - The Chronicle of Higher Education
Ms. Scheid, of RapidShare, said that installing filters that would check work for copyright violations before it is posted would violate strict German privacy laws. "So basically, this boils down to a discussion about how society wants to balance the need for protection of copyright versus the protection of data privacy," she said. "As long as this conflict has not been resolved in Germany, there will be more trials regarding this matter."

Students with disabilities are at significantly high risk of not completing their degrees. Campus staff can smooth the road for them by using universal design principles and fostering a climate of inclusiveness.
- Feb 26Better PDF File Size Reduction in OS X (Eric Meyer's blog)
I Googled around a bit and found “Quality reduced file size in Mac OS X Preview from early 2006. There I discovered that anyone can create their own Quartz filters, which was the key I needed. Thus armed with knowledge, I set about creating a filter that struck, in my estimation, a reasonable balance between image quality and file size reduction. And I think I’ve found it. That 175MB PDF gets taken down to 34MB with what I created.

- Feb 24Bringing test tools to Nagios monitoring :: semicomplete.com - Jordan Sissel
With all the TDD (test-driven design) and BDD (behavior-driven design) going around these days, it'd be a shame not to use these tools on monitoring applications.
You might have a boatload of tests that test your application before you roll a new version, but do you use those tests while the application is in production? Can you? Yes!
Let's take an important example of monitoring some complex interaction, like searching google and checking the results. Simple with a mouse, but perhaps complex in code. Even if you wrote a script to do it, using an existing testing framework gets you pass/fail testing automatically.
For this example, I'll use the following ruby tools: rspec and webrat. This fairly easy, though it took me a bit to find all the right documentation bits to clue me in to the right way.

HIVE is an automatic metadata generation approach that dynamically integrates discipline-specific controlled vocabularies encoded with the Simple Knowledge Organisation System (SKOS), a World Wide Web Consortium (W3C) standard. HIVE will assist content creators and information professionals with subject cataloging and will provide a solution to the traditional controlled vocabulary problems of cost, interoperability, and usability.
- Feb 23MarcXimiL - bibliographic similarity analysis
MarcXimiL is a free, flexible, fully standards-compliant and efficient bibliographic similarity analysis framework.
Similarity analyses may be set up at all levels of the process, run in batch or through the API. Options include:
* the order of comparisons between and within collections
* for each field, the selection of a parsing function
* for each field, the selection of a comparison function amongst a wide selection: vectorial (Dice, Jaccard, Salton's cosine), probabilistic (OKAPI BM25), Levenshtein based, Shingling, Authors, Date, and others.
* the global record similarity strategy (integration of fields similarities)
* the output format (XML, spreadsheet)
* thresholds at different levels - Feb 23Matching Dirty Data
A description of a method for matching bibliographic records when the only common identifiers are strings that are not exact matches.

- Feb 20LED series parallel array wizard
The LED series/parallel array wizard is a calculator that will help you design large arrays of LEDs. The LED calculator was great for single LEDs--but when you have several, the wizard will help you arrange them in a series or combined series/parallel configuration. The wizard determines the current limiting resistor value for each portion of the array and calculates power consumed. All you need to know are the specs of your LEDs and how many you'd like to use.
- Feb 18Welcome! » Tagalus
Ever find yourself looking at Twitter and wondering what all this talk about #motrinmoms means? Searching Flickr and not understanding why someone would tag their photo #ip4?
Tagalus lets users define tags so that others can understand what they're talking about. Other users can vote on definitions and decide which best describes the given tag.
You don't need to log in to browse the tags and definitions, but if you would like to contribute a tag, vote on a definition's authority, comment, etc. you have to use an OpenID to log in.
- Feb 12North Carolina State U. Gives Students Free Access to Physics Textbook Online - Wired Campus - The Chronicle of Higher Education
Physics students at North Carolina State University can get their introductory-level textbooks for free thanks to a new program by the college.
Each year about 1,300 students at North Carolina State take Physics 211 and Physics 212. Beginning this semester, the university's libraries and physics department have offered the courses' textbook online for free. Students can also print pages of the text or buy a printed copy at the university's bookstore for about $45.
