The Coming War Over the Future of Java 583

snydeq writes "Fatal Exception's Neil McAllister writes about what could be the end of the Java Community Process as we know it. With the Apache Software Foundation declaring war on Oracle over Java, the next likely step would be a vote of no confidence in the JCP, which, if the ASF can convince enough members to follow suit, 'could effectively unravel the Java community as a whole,' McAllister writes, with educators, academics, and researchers having little incentive to remain loyal to an Oracle-controlled platform. 'Independent developers could face the toughest decisions of all. Even if the JCP dissolves, many developers will be left with few alternatives,' with .Net offering little advantage, and Perl, Python, and Ruby unable to match Java's performance. The dark horse? Google Go — a language Google might just fast-track in light of its patent suit with Oracle over Android." Reader Revorm adds related news that Oracle and Apple have announced the OpenJDK project for OS X.

Tesla Roadster Data Logging Format Reverse Engineered 141

s1axter writes with word that "the data log format for the Tesla Roadster has been reverse engineered and documented, now available in Python. (Python script linked in the post.)" From the linked blog entry: "Not only was I given a $110k car unrestricted I was requested to see what ECU information is available, collect and parse the data from it. Tesla Motors periodically collects information from their vehicles presumably to see what real-world driving the cars see. On original Roadster models there is no method to collect this information remotely thus someone must go out to the vehicle and collect it. The owner of the vehicle saw this and wanted to know what information was collected on these service calls ... Because I am a big fan of freedom to modify a program to fit ones needs, I have uploaded the ... python script to parse Tesla logs."

How Cornell Plans To Purge Campus Computers of Personal Data 164

and so forth writes "Cornell lost a laptop last year with SSNs. Now, they've mandated scanning every computer at the University for the following items: social security numbers; credit card numbers; driver's license numbers; bank account numbers; and protected health information, as defined by HIPAA. The main tools are Identityfinder (commercial software for Windows and Mac), spider (Cornell software for Windows from 2008) and Find_SSN (python script from Virginia Tech). The effort raises both technical questions (false positives, anyone?) and practical issues (should I trust closed source software to do this?). Have other Universities succeeded at removing confidential data? Success, here, should probably be gauged in terms of diminished legal liability after the attempted clean up has been completed." Note: this program affects the computers of university employees and offices, rather than students' personal machines.

Building the Realtime User Experience 102

rheotaxis writes "Many professional web developers have spent years building dynamic, database-driven web applications, but some of us, like myself, want to make the user experience more interactive and instantaneous. The book Building the Realtime User Experience, by Ted Roden, is an introduction to some new techniques making that happen now. New web servers like Cometd and Tornado power solutions that keep HTTP connections open until data is available for the clients requesting it, a technique called 'long-polling.' This means web developers can provide a real-time user experience using HTTP for all sorts of client devices now connecting to the Internet, not just web browsers, but mobile devices as well."

Archbishop Bans Pop Music At Funerals Screenshot-sm 38

pickens writes "The NY Times reports that the Roman Catholic Archbishop of Melbourne has announced a ban on the playing of pop music at funerals, which, he said, are not to be described as 'a celebration of the life of' the deceased. According to new guidelines published on Archbishop Denis Hart's Web site: 'Secular items are never to be sung or played at a Catholic funeral, such as romantic ballads, pop or rock music, political songs, football club songs.' According to a cemetery contacted by Melbourne's Herald Sun, a list of more unusual songs played at Australian funerals includes: 'Always Look on the Bright Side of Life' by Monty Python, 'Another One Bites the Dust' by Queen, 'Highway to Hell,' by AC/DC and 'Ding Dong the Witch is Dead' from The Wizard of Oz."

KDE 4.5 Released 302

An anonymous reader writes "KDE 4.5.0 has been released to the world. See the release announcement for details. Highlights include a Webkit browser rendering option for Konqueror, a new caching mechanism for a faster experience and a re-worked notification system. Another new feature is Perl bindings, in addition to Python, Ruby and JavaScript support. The Phonon multimedia library now integrates with PulseAudio. See this interview with KDE developer and spokesperson Sebastian Kugler on how KDE can continue to be innovative in the KDE4 age. Packages should be available for most Linux distributions in the coming days. More than 16000 bug fixes were committed since 4.4."

How Should a Non-Techie Learn Programming? 346

CurtMonash writes "Nontechnical people — for example marketers or small business owners — increasingly get the feeling they should know more about technology. And they're right. If you can throw up a small website or do some real number-crunching, chances are those skills will help you feed your family. But how should they get started? I started a thread with the question on DBMS2, and some consistent themes emerged, including: Learn HTML + CSS early on; Learn a bit of SQL, but you needn't make that your focus; Have your first real programming language be one of the modern ones, such as PHP or Python; MySQL is a good vehicle to learn SQL; It's a great idea to start with a project you actually want to accomplish, and that can be done by modifying a starter set of sample code (e.g., a WordPress blog); Microsoft's technology stack is an interesting alternative to some of the other technology ideas. A variety of books and websites were suggested, most notably MIT's Scratch. But, frankly, it would really help to get more suggestions for sites and books that help one get started with HTML/CSS, or with MySQL, or with PHP. And so, techie studs and studdettes, I ask you — how should a non-techie go about learning some basic technological skills?"

Plone 3 Multimedia Screenshot-sm 31

Trevor James writes "Plone 3 Multimedia is an excellent book focusing on adding multimedia including images, audio and video files to a Web site built using the Plone 3 CMS. Overall this book has a nice balance and mix of text, screenshots and code. I recommend the book for Plone power users including Plone developers and users who want to enhance and expand their core Plone multimedia arsenal. You'll get more out of this book if you already have a Plone site running but want to add more multimedia based capabilities to it." Read on for the rest of Trevor's review.

Plone 3 Products Development Cookbook Screenshot-sm 52

RickJWagner writes "This book takes an interesting path to teaching Plone 3 development. Unlike most software instructional books, it starts way back in the often-unread Preface by listing 10 requirements a mythical customer is asking the reader to implement in Plone 3. The requirements are realistic and I think would probably be quite a stretch for an inexperienced Plone developer. The rest of the book is dedicated to implementing those 10 features, and coaching the reader on Plone 3 development along the way." Read on for the rest of Rick's review.

Finance, Scientific Users Get ActivePython Updates 131

jcasman sends along this clip from PCWorld: "ActiveState has added three open source mathematics libraries to its ActivePython Python distribution that might interest financial and scientific computing markets, the company announced Thursday. The packages are being added, in part, to anticipate the demand that may arise from new proposed rules for the US financial community brought about by the US Securities and Exchange Commission. ... In April, the government agency posted a set of proposed rules for handling asset-backed securities that called for financial firms to disclose, along with their prospectus filings, the source code of the programs that generated the filings, as rendered in Python. The government agency will be accepting input about the proposed rule until August 2. The three libraries that are being added to the ActivePython package are NumPy, SciPy, and matplotlib."

Blender 2.49 Scripting Screenshot-sm 51

terrywallwork writes "A few days ago I received an email from Packt Publishing informing me of their new Blender 2.49 Scripting book. I was very interested in reading this book as there are very few Blender books that cover the scripting aspect of Blender 2.49 and Python. So I navigated my way to the packt publishing website and ordered myself the ebook version. They were having a special at the time and I ended up getting a full color ebook for less than £9. If nothing else the price is extremely impressive." Read on for the rest of terrywallwork's review.

How CDNs and Alternative DNS Services Combine For Higher Latency 187

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."

Programming Clojure Screenshot-sm 109

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."

Exam Board Deletes C and PHP From CompSci A-Levels 663

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."

Matplotlib For Python Developers Screenshot-sm 119

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."
