Joomla! 1.5: A User's Guide, 2nd Edition Screenshot-sm 69

Posted by samzenpus from the read-all-about-it dept.
Michael J. Ross writes "There are countless content management systems (CMSs) available for building websites, and they offer varying levels of built-in functionality. But once a site developer has successfully installed any given CMS, a critical form of help (or hindrance) is the CMS's documentation, which for some CMSs is quite impressive, and for others absolutely atrocious. Joomla is a powerful and popular choice for Web developers, but can be daunting to newbies confused by its non-intuitive menu structure and restrictive content hierarchy. The documentation for Joomla is frequently criticized, for various reasons, and that may largely account for the popularity of third-party books — such as Barrie M. North's Joomla! 1.5: A User's Guide, now in its second edition." Read on for the rest of Michael and Ethelyn's review.

DOJ Gives Oracle Approval To Buy Sun 162

Posted by Soulskill from the nothin'-but-blue-skies dept.
k33l0r writes "The BBC is reporting that the US Justice Department has approved Oracle's takeover of Sun Microsystems. The acquisition gives Oracle control over (or a leading role in), among other things, Java, MySQL, (Open)Solaris, ZFS, OpenOffice, and the NetBeans IDE. 'The European Commission has still to rule on the deal, a step that will be required before it can close. That body has indicated it will issue an initial opinion on Sept. 3, according to the Wall Street Journal. It may OK the deal at that time or launch a four-month probe of it. ... The Justice Department ruling came earlier than expected, a possible response to Sun's declining revenues and precarious business position in a steep recession, as the required reviews proceeded.' We first discussed the deal back when it was announced in April."

Scala, a Statically Typed, Functional, O-O Language 299

Posted by kdawson from the means-scaleable dept.
inkslinger77 notes a Computerworld interview with Martin Odersky on the Scala language, which is getting a lot of attention from its use on high-profile sites such as Twitter and LinkedIn. The strongly typed language is intended to be a usable melding of functional and object-oriented programming techniques. "My co-workers and I spend a lot of time writing code so we wanted to have something that was a joy to program in. That was a very definite goal. We wanted to remove as many of the incantations of traditional high-protocol languages as possible and give Scala great expressiveness so that developers can model things in the ways they want to. ... You can express Scala programs in several ways. You can make them look very much like Java programs which is nice for programmers who start out coming from Java. ... But you can also express Scala programs in a purely functional way and those programs can end up looking quite different from typical Java programs. Often they are much more concise. ... Twitter has been able to sustain phenomenal growth, and it seems with more stability than what they had before the switch, so I think that's a good testament to Scala. ... [W]e are looking at new ways to program multicore processors and other parallel systems. We already have a head start here because Scala has a popular actor system which gives you a high-level way to express concurrency. ... The interesting thing is that actors in Scala are not a language feature, they have been done purely as a Scala library. So they are a good witness to Scala's flexibility..."

C# and Java Weekday Languages, Python and Ruby For Weekends? 389

Posted by timothy from the like-a-commercial-for-light-beer dept.
Dan Lorenc writes "Using the StackOverflow.com data dump, I measured the activity of various programming languages throughout the week. The results: Ruby and Python saw a rise in questions asked on the weekend while C# and Java saw a dropoff in activity on the weekend. This means that more programmers are using Python and Ruby on the weekend for their personal projects, showing that these languages are more fun to use. Show this experiment to your boss the next time you are selecting a programming language for a project at work."

First Look At Palm's Mojo SDK 128

Posted by timothy from the commodity-bits-making-a-new-whole dept.
snydeq writes "Peter Wayner puts Palm's Mojo SDK through its paces and finds the general outline of the system solid and usable despite 'numerous rough edges and dark, undocumented corners.' The main draw, of course, is the reliance on HTML, CSS, and JavaScript, which lower the barriers to entry, though with Mojo, HTML and JavaScript do at times work against each other, with JavaScript occasionally 'wiping out anything you do with HTML.' But more than anything, Wayner sees the current version of Mojo as 'merely the start of access to a very fertile platform. 'Developers are actively digging into the Linux foundations of the Pre and finding they can build tools that work with the raw guts of the machine. Some are talking about writing Java services underneath,' Wayner writes, pointing to sites such as PalmOpenSource.com and PreCentral.net that are cataloging dozens of apps that come complete with the source code. 'I know people are doing similar things with the iPhone — such as selling the source to people who must install it themselves — but the entire scene emerging around Palm has a much more organic and creative vibe. It's not getting hung up on parsing and reparsing the App Store rules.'"

Making a Game of Hardware Design 60

Posted by Soulskill from the sim-cpu dept.
no-life-guy writes "Researchers at the University of Michigan have developed a web-game to harness the natural human abilities for electronic design automation (EDA). Arguing that people are still much better than computers in games of strategy and visualization, and that we'll do anything as long as it's fun, a group created FunSAT — a game where an average Joe gets to solve a Boolean satisfiability problem. Known as SAT, this problem is an important component in various hardware design tools from formal verification to IC layout to scheduling. The pilot version is a puzzle-like single-player Java app (akin to those addictive web-games), but the researchers envision that it can be extended to a multi-player (and, perhaps, replace WoW as the favorite past-time of the millions), so anybody can be a hardware designer. If anything, this is definitely a great learning tool."

Sun's JRuby Team Jumps Ship To Engine Yard 77

Posted by kdawson from the just-in-case dept.
itwbennett writes "'To be honest, we had no evidence that Oracle wouldn't support JRuby, but we also didn't have any evidence that they would,' said Charles Nutter, explaining why Sun's entire 3-member JRuby team will be leaving the company to work for application hosting company Engine Yard. Nutter called getting hired by Sun about two-and-a-half years ago and being given the chance to work full time on JRuby a 'dream come true.' And said that the decision to leave Sun came down to making sure 'JRuby will get to the next level.'"

Google Open Sources Wave Protocol Implementation 183

Posted by timothy from the this-open-source-stuff-is-a-fad dept.
eldavojohn writes "Certainly one of the most important steps in adopting a protocol is a working open source example of it. Well, google has open sourced an implementation of the wave protocol for those of you curious about Google's new collaboration and conversation platform. It's been reviewed, skewered and called 'Anti-Web' but now's your chance to see a Java implementation of it. The article lists it as still rapidly evolving so it might not be prudent to buy into it yet. Any thumbs up or thumbs down from actual users of the new protocol?"

Best Tools For Network Inventory Management? 251

Posted by kdawson from the IPs-and-users-and-boxes-oh-my dept.
jra writes "Once every month or so, people ask here about backups, network management, and so on, but one topic I don't see come up too often is network inventory management — machines, serial numbers, license keys, user assignments, IP addresses, and the like. This level of tracking is starting to get out of hand in my facility as we approach 100 workstations and 40 servers, and I'm looking for something to automate it. I'm using RT (because I'm not a good enough Web coder to replace it, not because I especially like it) and Nagios 3. I've looked at Asset Tracker, but it seems too much like a toolkit for building things to do the job, and I don't want my ticket tracking users to have to be hackers (having to specify a URL for an asset is too hackish for my crew). I'd prefer something standalone, so I don't have to dump RT or Nagios, but if something sufficiently good looking comes by, I'd consider it. I'd like to be able to hack a bit here and there, if I must. Perl and Python, along with C, are the preferred implementation languages; least favorite is Java. Anyone care to share their firsthand experiences with this topic, and what tools they use (or built) to deal with it? "

Open Source Languages Rumble At OSCON 197

Posted by kdawson from the fairest-of-them-all dept.
blackbearnh writes "Everybody knows what the best programming language is, it's whatever one you like the most. But is there a best language overall? Or even a best language for a given purpose? This question has been debated since the first time there were two languages to choose from. The argument is still going on, of course, but maybe a little light will be shed on the issue this week at OSCON. On Wednesday night at 7PM Pacific, representatives of the 5 major open source languages (perl, PHP, Python, Java and Ruby), as arbitrarily decided by O'Reilly, will meet to debate the merits of their various languages. If you're not going to be at OSCON, you can watch it live on a webcast and pose questions or comments to the participants. The representatives are: Python: Alex Martelli, Google; Ruby: Brian Ford, Engine Yard; PHP: Laura Thomson, Mozilla; Perl: Jim Brandt, Perl Foundation; Java: Rod Johnson, SpringSource."

Collaborative Software For Pair Programming? 302

DavidMatuszek writes "I will be teaching Java again this Fall. Students work in pairs, but unfortunately (after the first hour) typically not physically together. I would like to find collaborative software that is (1) dead simple to use, because that's not what the course is about, and (2) free. Google Docs would do, but students will be sharing code — plain text — not RTF or HTML or Word files. Is there such software for plain text?"

Spyware In BlackBerry Updates For Users in the UAE 116

Posted by timothy from the this-could-happen-in-$yourcountry-too dept.
mulaz writes with this excerpt from The Register: "An update pushed out to BlackBerry users on the Etisalat network in the United Arab Emirates appears to contain remotely-triggered spyware that allows the interception of messages and emails, as well as crippling battery life. Sent out as a WAP Push message, the update installs a Java file that one curious customer decided to take a closer look at, only to discover an application intended to intercept both email and text messages, sending a copy to an Etisalat server without the user being aware of anything beyond a slightly excessive battery drain."

The Amazing World of Software Version Numbers 321

Posted by timothy from the remember-the-slackware-incident dept.
Harry writes "In theory, software version numbers should be incredibly mundane. In reality, companies have long twisted them for marketing purposes, avoided ones they didn't like, and even replaced them with things other than numbers. I've prepared a tribute to them with some facts and ruminations, but there's a lot I don't know, and I'd appreciate help on the historical side of things. (Anyone know when the standard decimal point-based system came into use?)"

Which Language Approach For a Computer Science Degree? 537

Posted by timothy from the do-both-and-compare dept.
wikid_one writes "I recently went back to college to finish my CS degree, however this time I moved to a new school. My previous school taught only C++, except for a few higher level electives (OpenGL). The school I am now attending teaches what seems like every language in the book. The first two semesters are Java, and then you move to Python, C, Bash, Oracle, and Assembly. While I feel that it would be nice to get a well-rounded introduction to the programming world, I also feel that I am going to come out of school not having the expertise required in a single language to land a good job. After reading the syllabi, all the higher level classes appear to teach concepts rather than work to develop advanced techniques in a specific language. Which method of teaching is going to better provide me with the experience I need, as well as the experience an employer wants to see in a college graduate?"

CJKV Information Processing 2nd ed. Screenshot-sm 52

Posted by samzenpus from the read-all-about-it dept.
stoolpigeon writes "At the end of last year, I made a move from an IT shop focused on supporting the US side of our business to a department that provides support to our operations outside the US. This was the first time I've worked in an international context and found myself, on a regular basis, running into long-time assumptions that were no longer true. My first project was implementing a third-party, web-based HR system for medium-sized offices. I found myself constantly missing important issues because I had such a narrow approach to the problem space. Sure, I've built applications and databases that supported Unicode, but I've never actually implemented anything with them but the same types of systems I'd built in the past with ASCII. But a large portion of the world's population is in Asia, and ASCII is certainly not going to cut it there. Fortunately, a new edition of Ken Lunde's classic CJKV Information Processing has become available, and it has really opened my eyes." Keep reading for the rest of JR's review.

Volunteer Programming For Dummies? 195

Posted by Soulskill from the learning-the-ropes dept.
Tios writes "I've been studying programming languages (C++, Java, C, Visual Basic) on my own with the self-guided, basic textbooks and tutorials, and I'm starting to get tired of working with examples that are not put into real use. I'm motivated to utilize my programming potential, but I've not had any experience programming in a team environment with lead developers, mentors, or collaborators. If finding a programming job isn't an option, I wonder if I could volunteer for programming in an open-source community. If this is a good idea, how do I start? What resources are out there that could get me oriented in volunteering? What kind of basic projects are out there, with a supportive team/mentor for me to develop, practice, learn, and contribute?"

First Fully Programmable Gesture-Recognition Glove, Cheap 77

Posted by timothy from the classroom-clickers-don't-capture-gestures-correctly dept.
Al writes "The AcceleGlove from AnthroTronix, is the first fully programmable glove that records hand and finger movements. Other gloves — like 5DT's Data Glove, which is used primarily in virtual reality — normally cost $1,000 to $5,000, but the AcceleGlove costs just $499. The AcceleGlove comes with software that lets developers use Java to program it for any application they wish. AnthroTronix initially developed the glove with the US Department of Defense for robotic control but it could also be used in video games, sports training, or physical rehabilitation."
