[OT] Hitler, Apple, Gates and Godwin’s Law

Perhaps there is a corollary (if not, let’s coin Roche’s Rule) to Godwin’s Law — briefly, that any discussion is practically over when it degenerates to metaphors of Naziism — that those who call off Godwin are in turn berated as thread police, censors, infringers on some divine human right to drag threads off topic and, yes, with all the irony involved, Nazis. In this response, I make the foolish mistake of not ignoring the troll bait. I am as guilty of overreacting as the hyperbole used by the original poster to compare Apple with Hitler.

Hitler burned, gassed, tortured, shot seven million Jews in concentration camps. Millions more, of all faiths, died defeating him.

The late Steve Jobs charged premium dollars (and sometimes outrageous fees!) to keep his company out there and competing in the tough markets of computers and software. Apple makes beautiful industrial design, often as impractical as Lamborghinis. They sell DRM-crippled music. They have pushed the envelope of consumer computing, much as Microsoft “innovated” back in the days when they had competition. Apple has sold a billion songs. I admire and respect Jobs, as an empire builder, like Gates and Olsen and Carnegie before him, but I don’t spend the money to buy many of his products, as I’m cheap. I have philosophical differences with Apple, too, but I’d probably buy an iPhone if I hit the lottery. They’re shiny. But, unlike some, I’m not betting my business on them.

Microsoft’s behavior has often been as outrageous as Apples, having been pulled into court a few times, regularly making their large corporate customers buy computers with Windows pre-installed and then pay again and again for licenses to run their OS, access their machines remotely, or run software on them, switching their license fees and terms and dropping products that are near and dear to all of our hearts. I’m not ABM as much as preferring what works best. Windows DirectX is supposed to be a good gaming platform. I hear XBoxes are great for Netflix. I use a Microsoft keyboard and mouse. I happen to think that Microsoft Windows on the desktop is here to stay, even with the incredible drag it puts on businesses with malware problems, poor performance and high cost. I do not, however, think that “the desktop” is here to stay, as a metaphor for people to do their business, and I look forward to Microsoft’s stranglehold on their clients breaking with some Next Big Thing. Off the desktop, I really don’t see Microsoft having contributed that much to the state of computing through their many (many, many) acquisitions. I prefer other brands for networking, server OSes, database servers, programming languages and technologies, not through some blind hatred as much as hard-earned experience. But that’s off-topic…

[The poster who tripped Godwin's Law...] ‘s post doesn’t have much to do with the topic of the thread, Linux, and is a really offensive comparison to some of us. Hitler and Naziism was one of the most horrific incidents of modern history and to minimize it by comparing it to shiny overpriced phones dehumanizes us all. Gates is not Idi Amin. The cellphone landscape does not resemble Dafur. Let’s get some perspective here, people.

There’s a difference between policing a thread, trying to manage to stay on topic, and censorship. I invoked Godwin’s Law to point out that the thread has likely run its course. You’re free to say what you want. I’m free to point out you’re off-topic.

So, if you want to keep on-topic on the “Linux Desktop Thread” I have some insight and informed opinions on the matter, having run Linux as my desktop for six years now, supporting a half-dozen clients with LAMP boxes in their offices, and developed some dozen or more LAMP applications. If you want to go off-kilter onto iPhones and Google as “liars and thieves,” why don’t you go start your own thread?

(Full disclosure: as I’ve mentioned before [blog.tedroche.com/disclaimers], I purchased a tiny bit of Apple stock a long time ago. It’s now worth a lot more than I paid for it, through no fault nor skill of mine. I also own tiny bits of Red Hat, HP and Microsoft. They’re still tiny. I don’t think this influences my opinion all that much, but I let my possible biases be known.)

Keeping up: theme changes

Astute readers (and I know who you two are!) will notice a change to a newer theme. I’ve switched over to the WordPress Twenty-Eleven base theme, with a few of my own tucks, nips and tweaks. I wanted to check out the new theme and test out the new functionality and keep up with the latest stuff.

Child themes are a piece of cake to create, and a child theme lets me override the original without messing with the original source, so updates will not erase the changes. While they are not so difficult to do manually if you are familiar with the command-line, they are even easier with the plugin One-Click Child Theme.

With the child theme in place, I was able to shorten the gap between the site description (the motto) and the header picture, just by adding CSS to the style.css in the child theme (that’s the cascading part of CSS). I added a paper-curl edge effect based on the work of Craig Buckler, published on Sitepoint.

I was disappointed that my site was not valid HTML5, according to the W3C’s validator site. Category tags used in REL links aren’t standard, so I deleted those. The Creative Commons plugins want to use Dublin Core XML namespaces, and there are issues there I’ve got to clean up. And the “generator” REL tag on the bottom of the page isn’t too standard, either. Overall, though, the pages are relatively clean of excessive markup or poorly-formed structures. Stay tuned as I tweak the last few elements into line.

NH Ruby September 2011: Backbone.js Jason Morrison

Twelve folks attended the September meeting of the New Hampshire Ruby Rails Group. Due to some logistical issues, we moved the meeting from NH-ICC to AlphaLoft, thanks to AlphaLoft member Nick Plante. Jason Morrison of thoughtbot was the featured speaker, talking about backbone.js.

Organizer Brian Turnbull got the meeting started with brief introductions.

Clients want the improved client-side experience of rich-client apps within the browser.

But which framework? Different patterns: MVC2 is what we’re used to seeing in Ruby/Rails. MVC and MVVM (Model-View-View-Model or Presenter).

Choice fatigue (http://www.nytimes.com/2011/08/21/magazine/do-you-suffer-from-decision-fatigue.html) : there seem to be more JavaScript frameworks than JS developers.

  • Capuccino – PowerPoint in the browsers, 270North
  • SproutCore (1,x,m 2.z) ricu Ui widget framework,.0 from the ground up rewrite, less widgets
  • Knockout.js: useds the HTML5 Data- elements
  • Batman.js – from Shopify, ActiveMerchant, using Node.js server-side component
  • JavaScriptMVC – mature, uses jQuery, filterable grids, lots of power
  • Spine.js – CoffeeScript, asynchronous front end, does full validation on client-side
  • Backbone.js – tonight’s featured framework, well-documented (in Doc-O)
  • Angular, Coherent, PureMVC-js, AFrameJS, TrimPath Junction,

Moving parts:

  • History
  • Router
  • View
  • Model
  • Collection
  • Sync
  • Underscore
  • $

Jason wowed the crowd with an excellent demo of an app under development and spoke eloquently of the power, and the dangers, of deploying MVC (or MV-something-else) into the client. His slides contained a great many good references. My laptop gave out at this point, so I didn’t take additional notes, but you can find his slides at http://jayunit.net/backbone-js-on-rails-talk and source for the slides at https://github.com/jasonm/backbone-js-on-rails-talk/blob/gh-pages/slides/index.md

One of the little things that got the crowd all excited was the line numbering on Jason’s Vim session: the current line was numbered 0, and line numbers incremented both up and down the screen. “Oh, that” Jason said. ‘set rnu’ is the command (see :help rnu within vim for details.)

Michael Tomer talked a little bit about his project, rocket.io, which is an interesting project trying to solve similar problems: “real-time” (no http lag) page updating, background sync between client and remote server. You can find his work at http://actsasbuffoon.com/rocket-io/

Thanks to Jason for an awesome presentation, to Nick Plante for hosting us at AlphaLoft, to Brian Turnbull for organizing the meeting, announcements and logistics, and to all the attendees for their participation.

NH Ruby meeting, 15 August 2011: Brian Turnbull, Rails 3

Brian Turnbull ran and presented to the August meeting of the New Hampshire Ruby Users Group meeting, held at the New Hampshire Innovation Commercialization Center. Over a dozen attendees turned out for the meeting, despite the inclement weather.

Brian presented an introduction to Rails 3 using a small application he had built for  work. He gave us an overview of the problem to be solved, skipping the irrelevant details, and explained how that fit into basic MVC concepts. We touched on the idea of design patterns. We examined or discussed many facets of Rails development, including rake tasks, migrations, fat models – thin controllers, using HAML for view templating, creating your own custom validators, deployment using Capistrano and more.

Brian mentioned several useful resources, such as Google, the Rails Guides, the API reference,  and more. He mentioned that he’d read Metaprogramming Ruby and thought that it changed his perspective on using Ruby.

As always, there was time for folks to get their questions answered. There were questions on stack dumps in rake, unobtrusive JavaScript, new features of Rails 3, Capistrano deploys to non-git-clients, and more.

Thanks to Brian for a information-packed presentation, and to all for attending and participating. Brian is always looking for ideas for future meetings and volunteer help in organizing.

 

Seacoast WordPress Developers Group, April Notes

On April 6th, the Seacoast WordPress Developer’s Group met at the New Hampshire Innovation Commercialization Center to talk WordPress. Networking and casual conversation started around 6:30, with the meeting formally starting at 7 PM with a round of introductions:

Dave – former Cold Fusion, ETL, new to WordPress,
Carl Eric Johnson – web developer, WordPress instructor and eveloper, fan of Thesis framework.
Amanda – BIL doing Joomla, Drupal, and WordPress
Sharon, Rye Public Library, Technology Coordinator, just launched a freshened site on April 1st using WordPress and Atahualpa theme/framework.
Will, a graphic designer in a print shop who’d been encouraged to learn web design and now WordPress.

Book recommendations:
Amanda praised the Wrox Professional WordPress book.
Eric has enjoyed WordPress: Visual QuickStart Guide to get up and running, and WordPress Bible(Aaron Barzell) from Wiley as a reference.

Main Presentation: Carl Eric Johnson: talk about themes and frameworks
Sitepoint.com Wicked WordPress Themes book has free sample download chapter. Table of contents points out the choices of custom themes, child themes, building a framework.
Child themes: load with parent’s theme files, in your child file, you import the parent, then override what’s different.
In WordPress 3.0, theme TwentyTen has a lot of options built in. Thesis and Atahualpa have a number of pages of options: sizing, features, colors, styles, etc.

Amanda talked about file structures and “the loop” – directories of wp-admin and wp-install are pretty much off-limits, containing the installed WordPress files and overwritten up updates; wp-content contains most everything else, including the stuff you customize. Add your own functions.php and copy the functions you want to override. A theme consists of index.php and style.css as a minimum; you can add as much as you want from there. See the Codex for the hierarchy of theme files WordPress looks for in order to render your content. Consider starting with a “blank” theme if you’re building your own, such as Starkers or Boilerplate themes – essentially stripped-down skeletal themes with all of the style removed.

See http://codex.wordpress.org/Template_Hierarchy for a description of how WordPress selects the correct template(s).

See http://codex.wordpress.org/The_Loop_in_Action for an overview of the loop.

Seacoast WordPress Developers meeting, 2-March-2011

Five people attended the March meeting of the Seacoast WordPress Developer‘s meetup, held at the New Hampshire innovation Commercialization Center near Pease in Portsmouth. We did a round of introductions and welcomed two new members and discussed what the group could focus on. We discussed the boundaries of CMS and Blogging and Wikis and how they overlap (A professional in education provided us with some great insights on how we think about some of these items), the challenge in finding consultants and clients, and how we can build up a network. We talked about potential agenda items: what should we schedule, what should we have in free-form.
I think an FAQ we ought to be prepared to answer is “What is it that WordPress is?” It’s less than obvious. “A blog” is the wrong answer, as that is a form of document, and not an application. “A CMS” is such a vaguely defined answer that it’s not much more useful than “an application.”

Other questions we started to explore, and possible future topics:

  • What is it that others are looking for on the web?
  • Good resources for learning WordPress: Codex, FAQ, books, etc.
  • WordPress SEO
  • WordPress Security
  • Loop/structure of databases tables, templates
  • Popular plugins
  • WordPress Backup tips: data and files
  • WordPress Community

Finally, Amanda presented her talk on building a plugin. She’d done some excellent research and used clear examples and explained them well. Here are the notes and slides posted to the new Seacoast WordPress Developer’s website, running WordPress, of course, and BuddyPress.

So, it was a great second meeting of the Seacoast WordPress Developer’s group. Stay tuned for more news. Thanks to Amanda for organizing the event, and to the New Hampshire Innovation Commercialization Center for providing the great facilities!

Color vim on CygWin

I’ve had to do some admin work on a Windows 2008 R2 server and found it handy to have a POSIX environment installed on Windows so I have ssh, grep, rsync, git, bash, vim and other functionality available all working within the same shell.

While vim was functional, the terminal was one that vim didn’t recognize as color, and hence the editor was only black and white and a few shades of gray. A little Googling returned this page: http://infrablue.tripod.com/cygwin.html with instructions on using rxvt as the terminal and configuring bash to run within it. A few tweaks, and I’m running vim and editing in color!

[UPDATE] @mintty_cygwin on twitter was kind enough to point out that rxvt development is pretty much stopped, but that the project http://code.google.com/p/mintty/ offered yet another TTY to run on Windows. This one has some pretty cool options, and is easy to install. I’m up and running with it now!

Notes from NH Ruby/Rails, 21-Feb-2011

Eight attendees made it to the February meeting of the New Hampshire Ruby Rails group at the New Hampshire Innovation Commercialization Center. A round of introductions included the usual suspects and several new people with interesting backgrounds and interests.

Brian Turnbull talked about Ruby debugging. He had a sample he created on Github Ruby comes with it’s own debugging library, but you can add a good one with a gem: ruby-debug.
Commands:
list – lists the code currently load
next – steps through the code listed, but skips over subroutines.
step – steps into the code
where – dumps the stack
finish – finishes the current subroutine call
display – dumps a value
(commonly use display value.inspect to make a cleaner display)
pp – pretty print, evaluates any Ruby code you want
edit – launches the EDITOR variable in our shell
catch – catch exceptions
cont – continue
break – set a breakpoint

,,, and so forth. Use the help, it is your friend.

The second example is far more complex, with a Sinatra app using OmniAuth and an LDAP provider. Following the supplied documentation, the app crashes on startup. (That’s what you get for reading the docs!) Debug and another tool – rbtrace to the rescue! Excellent demo of the problem and how the tools can debug them.

Seacoast WordPress Developers Group announce March meeting

Notes from NH Ruby/Rails, 17-Jan-2011: Brian Turnbull, OmniAuth, Nick Plante, Mirah

Seven members attended the New Hampshire Ruby / Rails group meeting held on 17-January-2011 at the New Hampshire Innovation Commercialization Center (NH-ICC). We had two presentations: Brian Turnbull talked about OmniAuth and Nick Plante showed a project he’s doing with Mirah on the Android platform.
Brian Turnbull is an engineer working for ARRIS and injects Ruby into his build tools whenever he gets the chance. A recent project required authentication against multiple providers and he did some research on OmniAuth. Brian presented a slideshow explaining the basic concepts of authentication and how they’re implemented in OmniAuth. Apparently, OmniAuth was the authentication method of choice during the most recent RailsRumble, used by most of the contestants. Brian outlined the process needed for working with an existing provider and demonstrated it with clear and simple code. He followed that up by showing how to build your own custom provider and authentication strategy. Brian’s sample code can be found on his github account.
Nick Plante has been working on an Android rich client app as part of a web-based social application that’s soon to launch. Nick told us that working on Java for Android has reinforced his love of Ruby. There’s not yet a good port of Ruby to the Android platform, but he has been impressed with the Mirah language, a hybrid solution that compiles to bytecode and runs natively on the JVM. He has developed a Ruby generator called protoform to construct the skeletons of a Mirah app. He gave us a tour of the components and built a simple “Hello, World” app, deployed and ran it on his Android VM.
Thanks to Brian for organizing the meeting and for the OmniAuth presentation, to Nick for talking about his Mirah project and to the NH-ICC for providing the fine facilities.
