Dashiva Dan writes "A little Python scripting goes a long way: Turn any song into swing with this script, which modifies the timing of the beats. Plenty of samples, hard to pick a favorite." This is a lot of fun to play with.

The_PHP_Jedi writes "Alternative DNS services, such as OpenDNS and Google Public DNS, are used to bypass the sluggishness often associated with local ISP DNS servers. However, as more websites, particularly smaller ones, use content distribution networks via embedded ads, widgets, and other assets, the effectiveness of non-ISP DNS servers may be undermined. Why? Because CDNs rely on the location of a user's DNS server to determine the closest server with the hosted content. Sajal Kayan published a series of test results which demonstrates the difference, and also provided the Python script used so you can test which is the most effective DNS service for your own Internet connection."

johnmccollum writes "A wealth of tools are available to debug and test Django applications, but knowing when and how to use these resources can intimidate the new user. Django 1.1 Testing and Debugging, by Karen M. Tracey, aims to walk the user through the process of creating a web application from scratch, ensuring that the resulting code is bug-free and ready for production."

eldavojohn writes "Programming Clojure by Stuart Halloway was very near to the perfect book for me. It covers many things common to many Lisp languages while highlighting in moderate detail the things that make Clojure unique and worthy of some attention. The book spends a large amount of time dealing with the intricacies of interfacing fluidly with Java (down to a package rewrite inside a large project). This fits me perfectly as a Java programmer, and I now feel ready to experiment with peppering functional language capabilities into an object oriented language. The book also strives to show how to simplify multithreading through functional programming, which is good because I find multithreading in Java a serious headache that few are good at. Programming Clojure, released in May 2009, is currently the only book out there devoted to Clojure, and the introduction is written by the language's creator, Rich Hickey, who says, 'What is so thrilling about Stuart's book is the extent to which he "gets" Clojure.' The book earns its place on the Pragmatic Bookshelf by guiding the user through rewriting a part of Ant into a new build tool called Lancet — adding to the project what you just learned about Clojure at the end of each chapter."

VitaminB52 writes "A-level computer science students will no longer be taught C, C#, or PHP from next year following a decision to withdraw the languages by the largest UK exam board. Schools teaching the Assessment and Qualifications Alliance's (AQA) COMP1 syllabus have been asked to use one of its other approved languages — Java, Pascal/Delphi, Python 2.6, Python 3.1, Visual Basic 6, and VB.Net 2008. Pascal/Delphi is 'highly recommended' by the exam board because it is stable and was designed to teach programming and problem-solving."

Craig Maloney writes "Ever since there was a collection of numbers, it seems that invariably someone will want a graph of those numbers. There are literally hundreds of different styles of graphs, and almost as many programs and tools to make those graphs. Matplotlib, a library and toolkit for the Python language, provides an easy and effective way to make some impressive graphics with little more than a smattering of Python. Matplotlib for Python Developers is equally impressive at distilling the core set of features of Matplotlib in a way that shows the reader how to get the most out the Matplotlib toolkit."

An anonymous reader writes "After six months of our new accelerated development schedule, MythTV 0.23 is now available. MythTV 0.23 brings a new event system, brand new Python bindings, the beta MythNetvision Internet video plugin, new audio code and surround sound upmixer, several new themes (Arclight and Childish), a greatly improved H.264 decoder, and fixes for analog scanning, among many others. Work towards MythTV 0.24 is in full swing, and has be progressing very well for the last several months. If all goes according to plan, MythTV 0.24 will bring a new MythUI OSD, a nearly rewritten audio subsystem capable of handling 24- and 32-bit audio and up to 8 channels of output, Blu-ray disc and disc structure playback, and various other performance, usability, and flexibility improvements."

briancarper writes "Vim is an open-source text editor with a power and flexibility matched only by the steepness of its learning curve.

An anonymous reader writes "A US federal agency is considering the use of computing languages to specify legal requirements. 'We are proposing that the computer program be filed on EDGAR in the form of downloadable source code in Python. ... Under the proposed requirement, the filed source code, when downloaded and run by an investor, must provide the user with the ability to programmatically input the user's own assumptions regarding the future performance and cash flows from the pool assets, including but not limited to assumptions about future interest rates, default rates, prepayment speeds, loss-given-default rates, and any other necessary assumptions.' Does this move make sense? If the proposed rule is enacted, it certainly will bring attention to Python or other permitted languages. Will that be a good thing?" The above quotes were pulled from pages 205 and 210 of the dense, 667-page proposal document (PDF). Market expert and professor of finance Jayanth R. Varma says it's a good idea.

rmoskal recommends his blog post up at Most Media on finding the right level of abstraction, Grails, and SOFEA. "[Three years ago] I was very excited about Apache Wicket as the way to develop line of business applications with a domain model, CRUD [create-read-update-delete] screens for maintaining the model, and in the most interesting cases, doing something else useful besides. I still like Wicket. It has, as its website says, a small conceptual surface area.' It reminds me of Python in that 'You try something it usually just works.' In many respects, though, Wicket seems to be at the wrong level of abstraction for the for the sorts of line-of-business applications described above. If your team is spending any time at all writing code to produce listing, filtering, and sorting behavior, not to mention creating CRUD screens and the back-end logic for these operations, they are probably working at the wrong level of abstraction. ... Recently I did a small project using Grails and was quite pleased. Grails uses groovy, a dynamic language compatible with Java, and is based on the proven technologies that I know and love well: Spring, Hibernate, SiteMesh, Maven, etc. ... I get all the power of the Java ecosystem without the fustiness and lack of expressivity of the core language (no more getters and setters, ever!)."

QuaveringGrape writes "After a few years of Python I've recently been trying to expand my programming knowledge into the realm of compiled languages. I started with C, then switched over to C++. A friend and longtime OpenGL programmer told me about NeHe's tutorials as a good step after the command-line programs started to get old, but there's a problem: all the tutorials are very Windows-based, and I've been using Linux as my single platform for a while now. I'm looking for suggestions for tutorials that are easy to learn, without being dumbed down or geared towards non-programmers."

An anonymous reader writes "The Australian Informatics Olympiad programming test is being run in a couple of months. I'm an experienced programmer and I'm thinking of volunteering to tutor interested kids at my children's school to get them ready. There will be children of all levels in the group, from those that can't write 'hello world' in any language, to somewhat experienced programmers. For those starting from scratch, I'm wondering what language to teach them to code in. Accepted languages are C, C++, Pascal, Java, PHP, Python and Visual Basic. I'm leaning towards Python, because it is a powerful language with a simple syntax. However, the test has a run-time CPU seconds limit, so using an interpreted language like Python could put the students at a disadvantage compared to using C. Is it better to teach them something in 2 months that they're likely to be able to code in but possibly run foul of the CPU time limit, or struggle to teach them to code in a more complicated syntax like C/C++ which would however give them the best chance of having a fast solution?"

jafo writes "There's been a lot of teeth gnashing going on recently about broken wireless at conferences. We just wrapped up PyCon 2010, with around 600 (out of 1,000) attendees simultaneously accessing the volunteer-run network, and response has been fairly positive. 2.4GHz (802.11b/g) continues to be problematic, but most users were on 5.2GHz (using 802.11n) and associating at 130mbps, with a 100mbps link to the net (though after the fact we found that 35mbps would have sufficed). My PyCon 2010 wrap-up reveals all the secrets of how we did it, including pretty bandwidth and user graphs."

jonverve writes "In May of 2009, the White House launched an Ideascale site to gather ideas from citizens to identify ways to 'strengthen our democracy and promote efficiency and effectiveness by making government more transparent, participatory, and collaborative.' The digital letdown was when many of the top ideas generated by the process were to legalize marijuana, solve tax issues and to reinvestigate Obama's birth origins. Fast forward to February 6 and the same process has been repeated with individual federal agencies as the subject. This time the idea generation has been much more productive, with ideas such as establishing clear benchmarks on humanitarian progress in Sudan to the State Department, funding for open source text books and materials to the Department of Education, making it easier to access previously FOIAed documents to the Department of Justice, and creating a Wiki for NASA to share its data and to engage the public. Hackers from NASA's Nebula cloud computing platform have created a site that aggregates 23 of these idea sites to give a quick peek into the best rated contributions in each category. Programmed in Python and using the MongoDB and Tornado web server, the Open Gov Tracker was highlighted by the open government blog Govfresh this past week as well. Jessy Cowan-Sharp, one of the creators, explained their motivation: 'We thought that a single access point would give a sense of the participation on all the different sites, a window into the discussions happening, build some excitement, and inspire people to participate.' The process closes on March 19th, so go and visit the site to contribute your ideas and vote!"

Instead of lining up a fabulous type of gorilla that thrives on snake meat, Florida officials have decided to open a season for hunting pythons. Anyone who has a hunting license and gets a $26 permit can kill the snakes from March 8 to April 17 on state-managed lands around the Everglades in South Florida. In addition to the non-native pythons, hunters are encouraged to kill any green anacondas and Nile monitor lizards they might find.

thatpythonguy writes "Learning Python is a well-written book by an experienced Python trainer that has served the Python community well since the first edition was published in 1999.

BeardedChimp writes "I, like many others here, have learned to program by myself. Starting at a young age and learning through fiddling I have taught myself C++, Java, python, PHP, etc., but what I want to know is what I haven't learned that is important when taught in a traditional computer science curriculum. I have a degree in physics, so I'm not averse to math. What books, websites, or resources would you recommend to fill in the gaps?"

Jack Spine writes "With nearly a billion users dependent on smart banking credit and debit cards, banks have refused liability for losses where an idenification number has been provided. But now, the process behind the majority of European credit and debit card transactions is fundamentally broken, according to researchers from Cambridge University. The researchers have demonstrated a man-in-the-middle attack which fooled a card reader into accepting a number of point-of-sale transactions, even though the cards were not properly authenticated. The researchers used off-the-shelf components (PDF), and a laptop running a Python script, to undermine the two-factor authentication process on European credit and debit cards, which is called Chip and PIN."

coondoggie writes "Computer users with rudimentary skills will be able to program via screen shots rather than lines of code with a new graphical scripting language called Sikuli that was devised at the Massachusetts Institute of Technology. With a basic understanding of Python, people can write programs that incorporate screen shots of graphical user interface (GUI) elements to automate computer work. One example given by the authors of a paper about Sikuli is a script that notifies a person when his bus is rounding the corner so he can leave in time to catch it." Here's a video demo of the technology, and a paper explaining the concept (PDF).

stoolpigeon writes "It has been ten years since David Beazley wrote the first edition of Python Essential Reference. The book has proven itself as a valuable resource to Python developers and has been kept current over those ten years, with the fourth edition coming at an interesting time for Python. Python 3 was a major release that broke backwards compatibility. Python 3 has been around for a year now. That said, the current download page at the official Python site states, 'If you don't know which version to use, start with Python 2.6.4; more existing third party software is compatible with Python 2 than Python 3 right now.' Beazley, in keeping with the pragmatic roots of a reference that sticks to what is 'essential,' has removed the coverage on features from 2 that were removed from 3. At the same time, the primary focus for new features that came with 3 is limited to those that have been back-ported to 2. This approach, born out of a desire to keep the reference relevant, provides a blended approach that is above all else practical." Read on for the rest of JR's review.
