Developers, developers, developers song gets covered again

By on May 1, 2008 in Home Page, MySQL, OpenSource, Ruby, Web Development

We all know the answer is “Developers, developers, developers, developers,” but who’s asking the question these days? It seems like Sun has taken up the song, according to Timothy M. O’Brien’s posting over at O’Reilly, “Surprising Contender: NetBeans as a Ruby+MySQL IDE.” Great news for all of us looking for new tools; NetBeans is shaping up to be a pretty sharp IDE.

I saw a blog post recently and neglected to bookmark it that posited the thesis that rich IDEs were bad when learning a language. A simple text editor and console can be all the interface you might need when when starting off and as your skills increased, the need for code completion, cross-referencing, inline debugging, source code control, refactoring and macros all became more valuable. Witness the training videos on http://www.rubyonrails.org where developers use a browser, a console window and the Textmate editor to build sample applications. The simplicity is appealing.

Continuous Learning Curve: Javascript

I’ve avoided spending too much time delving into Javascript. My four-year switch from Windows-uber-alles (including VFP, VSS, SQL Server, Ingres, Oracle, HTML, OLE, ODBC, SCC, COM, XML, MCSE, MCSD, XSLT, DCOM, RSS, MS Office, Exchange, MAPI Bad, SMTP Good, MVP and more acronyms!) to Linux-Apache-MySQL-Postgres-PHP-Python-Ruby, not to mention XHTML, CSS, bash, Smarty, Django, TWiki, dojo, et al had kept me busy enough. But a new client assignment needs a highly-interactive web site and dropping in great big globs of someone else’s Javascript is not going to solve all the problems; at a minimum, I’ve got to be able to read it, debug it and tune it for the client’s particular needs.

Did you know that a limited version of Safari, the O’Reilly online library, is included with a membership to the Association of Computing Machinery? I’ve been an ACM member for years and been meaning to get around to trying this out. My Javascript studies seemed the perfect occasion. I’m reading Shelley Power’s Learning Javascript online and getting quite a bit out of it. I love when you settle down with a book and start going “Oh, is that what that meant?” or “Now I get it!”

Notes from NH Ruby group, 15-April-2008

By on April 16, 2008 in Apple Macintosh OS X, Home Page, LAMP, Linux, OpenSource, Ruby, Technology, Web Development

Eight people attended the April meeting of the Ruby Special Interest Group, http://www.nhruby.org, held as usual on the second Tuesday of the month in the meeting room at RMC Research.

We lead the night off with a brief video on Passenger from Phusion.nl, a new Apache module that host rails, like a mod_rails (not _ruby) module. Nick reported he’s been running it on one of his sites for a while and is pleased with the performance and the marked decrease in load. Having a mod_rails option available is likely to get hosting companies offering fractional horsepower shared virtual machines to be able to host Rails apps, bringing Rails onto the $7-a-month commodity hosting sites. Cool!

I asked for recommendations on the right way of parsing incoming XML and SOAP packets and was referred to Hpricot and soap4r. Another attendee asked for recommendations on Content Management Systems. Nick mentioned Radiant (which we got to see later in the presentation). comatose and railfrog. We got into a couple discussions during the evening on the stability and applicability of Ruby and Rails for many situations, citing high traffic web sites and the several runtime engines/VMs like JRuby in which Ruby code can run.

Finally, we arrived a the Live Hacking session where we got to watch Scott and then Nick show how to add new functionality to an existing app. Actually getting to see another craftsman at work brings out all sorts of good questions. Scott added chronic to his To-Do application. Chronic is a “natural language datetime parser,” according to the web site, and Scott showed how it could easily be integrated into an existing app, and accept values like “Next Tuesday” or “Thursday last week” and return sane datetime values. We also looked at what would be involved and set up a unit test to check our changes.

Nick showed us a little more of the Radiant application, and his work on making the Radiant CMS support multiple sites. The source he’s working on is stored at github.com, and the networking graph is a thing to behold. Nick spent a little time getting us familiar with the different philosophy of git (branching is inexpensive, merging is very smart, branches can interact in many ways including pushing to and pulling from each other) and then grabbed the most recent code and hopped right into to refactor a code snippet that was an inelegant hack using a deprecated technique into one that was more proper, running our unit tests before and after to confirm the refactoring didn’t break anything.

An excellent evening as usual! Thanks to all for their attendance and participation, to Scott and Nick for organizing, announcing and presenting, and to RMC Research for providing the nice facilities.

Notes from MonadLUG, 10-April-2008: Guy Pardoe and Joomla

By on April 12, 2008 in CSS, LAMP, Linux, MySQL, OpenSource, PHP, Web Development

Sixteen people were present for the April Meeting of MonadLUG, the Monadnock Area Linux User Group meeting, held as usual on the second Thursday of the month at the School Administrative Unit #1 main office off Hancock Road in Peterborough.

As is usual with most LUG meetings, we spent the standard ten minutes wrestling with monitor settings for the cool new projector. We couldn’t do better than 640 x 480 so Guy was a trooper and persevered through the presentation at teeny resolution. Ouch. We’ll have to do some research to figure out how to get this new projector system to rock and roll.

Guy reminisced about his last presentation, (February last year) where he had talked about the new version of Joomla, which was due Real Soon Now and how he had promised to be back when it was released. In April of 2008, he was back to report that 1.5 is released, and the wait was worthwhile. In fact, version 1.5.2 is out now.

There was a discussion of the many new content management systems – Drupal is another one that’s received a lot of attention. Guy had also heard another one – ModX (http://modxcms.com/) that he hears all the cool kids are playing with.

Guy talked about how the web grew up in a table driven layout just to get positioning right, and that as css came along, that was prefered. Joomla templates are nearly always 100% CSS and valid HTML with few or no tables, and how there’s a lot of advantages from better accessibility, easier localization, better search engine optimization and fewer cavities.

As part of his presentation, Guy downloaded the .zip from the web site www.joomla.org, un-zipped the package, copied to an install directory, ran the installation (a pre-flight check, verified versions, etc.) and he was up and running (Joomla reminded to remove installation). Members noted that Guy showed them things about file management using the GNOME file manager that no one had bothered to try, since they would have all done it from a shell. Guy didn’t apologize for being a Windows refugee. There’s more than one way…

Guy talked about the first presentation of Joomla we saw, from Barrie North on 7 September 2006 at DLSLUG. Barrie has recently published a book, which Guy had with him and praised.

Guy gave us tour of the interface, both the public presentation and the administrative interface. Built-in default templates are pretty slick. The setup wizard was quite graceful. And addons and replacement templates seem to be available in huge quantities (Ted: downloading code off the internet and installing it to run on your computers without inspecting and understanding the code is a Bad Idea. Use only trustworthy sites and review what you get.)

Finally, Guy showed off a site he is developing for a client at Bristol Elder Care and talked about what was involved in getting the site up and running.

Thanks to Guy for a great presentation, to Charlie for organizing the meeting, to Ken and the SAU for the great facilities.

Check out NetVibes!

By on April 9, 2008 in CSS, JavaScript, OpenSource, PHP, Web Development

In searching for Prototype Windows and related JavaScript libraries to let us create portlets for a portal, we’ve run into a couple of pretty impressive contestants. The most recent is NetVibes, which appears to be both the name of the web site (“Build your own portal!” “Share it with your friends!”) and the underlying libraries and Universal Widget API specification. Very slick web site, very slick GUI libraries!

Listening last week to… April 5, 2008

By on April 6, 2008 in Home Page, OpenSource, Python, Technology, Web Development

Backdating this post a bit, as I didn’t get it posted yesterday,…

In Fresh Ubuntu, Harlem and Peter lead off this week with a conversation with Michael Ramm about productivity and GTD in “Michael from Blackbelt Productivity.”

PyCon2007 had a good and a not-so-good set of audio recordings: “Python and wxPython for Experimental Economics” was quite interesting, though there wasn’t as much deep programming insights as an interesting diversion about experimental economics. “Iterators in Action” (slides) was a flop, though. The recording was in the back of an echoing hall, and cut off in a little less that twelve minutes. I’ll ping the organizers to find out if that can be resampled.

Clay Shirky talks to Moira Gunn on Tech Nation “Here Comes Everyone.” Clay did one of my favorite presentations of all times, audio available on IT Conversations and a white paper here. Clay’s got a new book out and he’s marking the rounds of the media. I heard him on “On the Media” last week.

Tim Spaulding talks with Jon Udell about LibraryThing. in Jon’s “Interviews with Innovators” series on IT Conversations. I mention LibraryThing two years ago on this blog, and have been a regular visitor to the site. They continue to come up with intriguing features and make browsing through the stacks a lot of fun.

What I’ve listened to this week, 29-Mar-2008

By on March 30, 2008 in Home Page, OpenSource, Python, Ruby, Technology, Web Development

PUI (Podcasting Under the Influence), Peter Nikolaidis is “drunk with the power” of swapping roles with his co-host Harlem for this week’s podcast of “Fresh Ubuntu,” titled “Peter’s Big Break.” These two guys put on a very good show each week, with high-quality audio, the week’s Linux/Ubuntu news, a “man page minute,” software reviews and more. Worth a listen. (Yes, they read a letter from me in this episode. At least I didn’t write too gushy a fan letter. How embarrassing.)

Over at The Conversations Network, Executive Director, Doug Kaye has a brief posting and audiocast on the new features of The Conversations Network. They are a 501(c)(3) non-profit organization that provides tremendously useful audiocasts for any computer professional. I’m a donor (the fact that I’m a “major” donor is an indication of how underfunded they are!) and encourage you to take a listen and contribute if you find it as valuable as I do.

Jon Udell has a regular “Interviews with Innovators” show on IT Conversations. This week, he talks with Ward Cunningham, famed creator (and co-author of the book of the same name) of “The Wiki Way,” about his latest venture and some of things he’s learned along the way.

Cyndi Mitchell had a sponsored keynote at RailsConf 2007 promoting the RubyWorks stack for the enterprise.

“The Essentials of Stackless Python” from PyCon 2007, NOT from the Conversations Network, but direction from python.org

Tim Bray’s keynote at O’Reilly RailsConf, via IT Conversations

By on March 20, 2008 in LAMP, Linux, OpenSource, Ruby, Technology, Web Development

What I’m listening to this week: IT Conversations | O’Reilly RailsConf | Tim Bray. From the It Conversations website:

In this keynote presentation, Tim Bray, the Director of Web Technologies at Sun Microsystems, covers a broad range of topics such as Sun’s interest in promoting Ruby, the case for JRuby in the enterprise, the areas Ruby needs to improve on, features that may be good extensions to the Rails framework, REST, HTTP Etags, caching in Rails, the Atom publishing feed, Microsoft’s WCF and Sun’s business model of making all its products open source.

Tim’s a great speaker, and has a lot of interesting insight into Ruby and Java and Sun. He makes no bones about the fact that he’s a paid-for speaker, since Sun was a sponsor of RailsConf, gets in his obligatory plug for Sun, but also talks insightfully about the ways that Ruby can scale better on top of Java, and that Sun’s looking forward to selling lots of boxes when it does.
