Local Government 2.0

by

Government 2.0 is a big interest of mine – just like at the national level, I think we can make local government more open, participatory and productive by using technology intelligently. Although there’s been talk about this for a while, it’s still early days – e.g. see the new discussion, “What Is Government 2.0?” at the Gov 2.0 ning site.

One example: at Imagination Coast, we’ve formed a Data Visualization group to use graphics to help investors and decision-makers understand the challenges and opportunities in the Central Coast’s sustainable economy.

With the Community Alliance for Safety and Peace, I’m exploring similar ideas for coordinating the many government, law enforcement and non-profit organizations involved in the effort to reduce gang violence in Monterey County. For example, a unified client-centered database of at-risk youth and their families, so that we can devote the same level of attention and customization to helping an at-risk youth stay alive as we would lavish on a customer for a new soda pop. This amounts to adapting the practices of Customer Relationship Management to social services.

Obama: Advancing Civil Liberties in the Face of Difficult Constraints

by

My opening statement for the debate at the ACLU Santa Cruz Annual Dinner, Nov 18, 2009:

Thank you for this opportunity to present the civil liberties record of President Obama. I believe that record is already impressive, and I believe it promises to be historic.

Before I begin, let me emphasize that although I worked for President Obama’s election campaign, I do not work for the Obama administration and I speak only for myself here this evening.

When then-Senator Barack Obama was considering whether to run for president, his advisers asked him the simple question that all candidates must be able to answer: “Why should people vote for you?” Part of his answer was this: that on the day he took the oath of office, there would be children all over America who would think differently about what was possible for them.

Top Drupal Gotchas, #2: White Screen / Not Enough PHP Memory

by

Cross-posted at O’Reilly Broadcast.

Continuing my effort to spare newcomers to Drupal from falling into this powerful content management system’s most common traps, this time I look at a frequent cause of white screens – the sudden and scary devolution of a previously healthy Drupal site into a blank browser window.

This can be caused by coding mistakes, such as neglecting to conclude a line of custom PHP with a semicolon.

But white screens often happen to new Drupal admins who haven’t yet come near any custom PHP. The typical story is that you install a new module and suddenly – poof, there goes the site. You might assume that the new module is buggy or incompatible with your site.

But the cause is often simply that your web server has run out of memory for executing PHP. Since at heart Drupal runs on PHP interacting with an SQL database, your site can’t bootstrap to begin writing any html pages.

Under many web hosting accounts, the default setting for memory allocated to PHP is quite low – on mine, it’s 8 MegaBytes. But it’s not uncommon for a Drupal site with extra modules installed to require 96 MB or more.

In order to increase PHP’s memory allocation, you need access to your web server’s PHP initialization file, which is called php.ini. (You won’t have this access with web hosting plans that restrict you to the site’s home directory, since php.ini is typically found higher up the directory tree, such as in the /etc folder if you’re using Apache.)

When setting up a new Drupal site to which you plan to add extra modules, find your server’s php.ini file, open it and search for this line:

memory_limit = xM

…where “x” is some integer, such as 8. If it’s a small number like that, replace it with something more appropriate. Some Drupal modules will give you guidance on this in their documentation. I’ve found that 96 MB is a good starting point.

Save the newly edited php.ini file, and you should now be safe from memory-related white screens.

But whatever the cause of a particular problem, all of them are arguments for routinely backing up a Drupal site and its database, and/or for trying out significant changes on a test site before deploying them to the public site.

ACLU Debate: Defending Obama’s Civil Liberties Record

by

I’ll be arguing the position “Obama: Advancing Civil Liberties in the Face of Difficult Constraints” at the ACLU Santa Cruz chapter’s annual meeting Wednesday, Nov 18, 2009, starting at 7:00 pm.

From the ACLU: “Each speaker will have opportunities to stake out their positions, to rebut their opponent’s statements, and to offer a final conclusion. Following the debate, the floor will be opened for questions and comments from the audience.”
