hfs+ on linux

I got a new MacBook from work and need to migrate files from my old Dell notebook running Xubuntu Linux.  Luckily, I had recovered a drive from a bricked machine that was donated to pages that I could use to transfer the files.

I don’t like the Fat32 file system, so I formatted the external drive as hfs+.  My workstation, running Debian, mounted the drive fine, but I couldn’t write.  I found that I had to disable journaling on the drive before I could write it in Linux:

$ diskutil disableJournal /Volumes/ghingexternal

Note: that command has to be run on the Mac.

Once I did this, I could write to the disk, but only as root.  Permissions of hfsplus partition, a thread on the Ubuntu message boards, provides this insight which is likely the case:

I have to preface my entry with the warning that I am a complete newbie. I was having the same problem with accessing my files on my hfs+ partition. What I discovered is that by default OSX doesn’t allow any access for the gid for files and folders in your User’s folders. I don’t know if this is the wisest thing, but I went into the Finder, did a “Get Info” on all the files/folders I wanted to access in Ubuntu, I then went under permissions and switched the Group ID to something I could use in Ubuntu. I then made sure that the line in the fstab that mounts my hfs+ partition had a “gid=XXX” statement that matched what I set in OSX. I also made sure that the user I was using in Ubuntu was part of the group mentioned above. If this doesn’t make sense, let me know and I will clarify. Also, if you need help with OSX permissions, here is a link to an Apple KB article: http://docs.info.apple.com/article.html?artnum=107039

Mailman Subscription Form with Drupal’s Webform

I’m trying to use Drupal’s webform module to make a subscription form to a Mailman mailing list.  Tracking thoughts and problems here.

I like webform because it stores form responses which might be useful.

Webform also lets you send e-mail on form submission and specify the sender/subject.  I was going to use this to send an e-mail from the address that user enters in the form to the -request address of the mailman list.

The problem is that the module lets you set the From: header but not the Sender: header and mailman uses the Sender: header to detect the requestor.

Options

  • Find a way to use tokens to set the subject to be ‘subscribe address=<form_submitted_address>’
  • Try to send my own e-mail with PHP code specified in the Additional Processing textarea of the Webform advanced settings fieldset when editing my form.

Core technologies/concepts for community organizing

Last summer at the AMC, I presented a session about Web 2.0 and social movements.  Because I inherited the session from someone else, I kept the session proposer’s rubric of introducing technologies/services by name  (Twitter, Jott, del.icio.us) so that people would be able to link the name/buzz with an idea of what it could do.  If I had it to do all over again, I would start with core concepts and technologies that I see as being really helpful with my own use of tech. in organizing.   These would be things that underly a lot of Web 2.0 services and also make technology more fluid for users of all levels of technological familiarity. I’m starting a list here.  What core concepts/technologies do you all use?

RSS Feeds/Aggregation

One of the biggest frustrations that I (and other users I would suspect) have with the multitude of useful sites is having to have a bunch logins and remember which information lives where.  One has to choose between using the right tool for the job and making it easy to locate and access information.  E-mail is one convergence point, but that doesn’t neccessarily mesh with every service that people might use.  Services from del.icio.us to Twitter to Google Calendar to most blogging platforms all allow you to publish RSS feeds.  I would explain what a feed does, show what a feed looks like in various services, and then show how to aggregate and organize feeds with a web-based aggregator and a desktop app.

Feeds are so important because understanding them is crucial for mashing up services or making them easier for collaborations.  Examples:

  • Blog to twitter using Twitterfeed
  • Twitter “mailing” list using #hashtags and RSS Feed for http://search.twitter.com/

Email Filters

People are often overwhelmed by mailing lists, but few know that you can pretty easily filter out all the different kinds of e-mails that you get to do the inbox triage that everyone is familiar with for you.  I think having imapfilter or Thunderbird sort my mail into folders is super-useful, if only to evaluate the actual importance of data.  If I never click on a partcular folder where some of my mail is auto-sorted, do I really need to be on that mailing list anyway?

Human URLs (TinyURL or similar services)

Things like Google Docs often generate long, difficult to remember addresses for important information.  If people have to first dig through an e-mail with a link to a shared resource (and do this every time they want to access it), they’re going to be less likely to use it.  If they can just remember it (or enough of it that it is found in their browser’s location history) I think these online resources will get more use.

Mailing Lists

I think we all take these for granted, but there are ways to use these that make them more or less effective.  What strategies do you use to handle list management and message moderation.  How do you not flood people’s mailboxes?  How do you make it easy for people to (un) subscribe to lists?  This is more a discussion of usage than particular technologies.

Chat

Electronically mediated communication can often be ambiguous.  I find that I often spend extra time trying to disambiguate something in e-mail when it would have been way, way faster to call and let someone as questions.  Still, a lot of collaboration that I do involves looking at text or files together.  Chat is really crucial for these kinds of tasks.  I use it every day at work.

SMS

I don’t have a texting plan and I share my mobile phone, so I’m not the hugest txter but I like that it’s more purvasive than e-mail but less intrusive than a phone call because it lets people get the information first before deciding their timeline or content for response.  It’s also better than a call or voicemail for infromation that you might have to lookup again (a phone number or address for instance).

Skype/Conferencing

For the times when you want to be more personal than chat, voice/video conferencing is perfect.  We have a fancy system at work for having meetings that span Indy and Bton but I think folks can achieve much of the same functionality with Skype, cheap webcams, and projectors.

Paypal

Cash rules everything around me … There are probably better alternatives, especially if the organization seeking cash is a 501(c)3, but Paypal is definitely the easiest to use.  The awesome Pledgie service helps you use Paypal to organize campaigns.

Institutional Clash

Comments on web sites often make me sad, but it’s good to see how complicated and often conflicting the experiences and perspectives of people are, like this exchange between 2 Wisconsin DOC employees from a pretty one-sided article about contraband in WI prisons.:

It is Taycheedah Correctional INSTITUTION, not CENTER. The State Journal needs to fact check. THIS IS YOUR JOB!

This is a poorly written, overly biased article. Being locked in a cage all day, for months or years does breed violence. And many of our inmates do sell drugs and weapons. But where is the mention of the black-market sale of athletic shoes for use in the gym? Or the manufacture of small toys to be sent home for a child’s birthday? Wisconsin’s inmates are people too and upon release they DO deserve the chance to prove themselves and rejoin society. ARTICLES like this simply perpetuate and foster more hate and discrimination for ex-cons. Not all of our prisoners are murders and rapists…some are children who have made mistakes or adults who want to change their ways. Let them return to society and restart their lives in peace, without making it more difficult for them by encouraging prejudice.

You know, DocEmployee, people like you are what’s wrong with the Department these days. I’ve been in this business for a long time now, I honestly didn’t think there was one thing in this article that was out of place or inaccurate. By your logic and remarks it appears that you are the type of officer, that when my two brothers in blue got their heads smashed in 2 months ago by an inmate with a hammer, you’d be quick to blame us for giving him the hammer! Or maybe it was an error on clinical services for allowing the inmate to have the job in the first place? If you are going to speak like that, do us all a favor and do so under your own name and keep the rest of your BROTHERS and SISTERS out of it.

Sundown Towns past and present

I’m in the process of reading the book Sundown Towns and I just started the chapter about “triggers”, or events that Whites used to rationalize running all the Black residents out of town.

I was just watching PBS’ Independent Lens when I saw this documentary about Tulia, Texas.  The story sounded all too familiar …

Single gender classrooms

This article came across my feed reader.  From the article: “The practice of separating girls from boys in the classroom was the norm decades ago. Now, it seems to be something of a new trend.”

A few thoughts … I read a book on gender and computing that said that while girls do better in single gender classrooms (I think this was specifically wrt math/science) boys do better in mixed-gender classrooms.  This article mentions that in one school, classes are multi-gender for things like gym and computer lab time which seems strange since the aforemetioned book identifies computer education as one of the areas where learning is most gender-mediated (and gym just intuitively seems terribly gender-mediated).  Finally, I would really like to know if anyone has tried to have single gender sessions a few times a week, then merging for classes.  Would this allow different learning strategies to emerge and solidify in the gender-specific classes and then, when shared in the mixed-gender session, students of all genders could pick the strategy that worked best.  Would this not work because students would judge strategies as “girl” or “boy” strategies rather than evaluatng them on their effectiveness or creativity?  Would the confidence in the strategies that might be built from the single-gender classrooms allow people to advocate for their approaches in a way that would convince their classmates despite gender prejudice?

“Oh, Susquehanna” and the geography of race

In the Defiance, Ohio song Oh, Susquehanna, I always envisioned rivers and the Susquehanna, familiar to me from where I grew up, as a metaphor for organic connectedness and aknowledgement that our lives have implications on our neighbors.  The metaphor is imperfect since, when used for our means, rivers become not only connectors but barriers.  As I recently read in James W. Lowe’s Sundown Towns:

Unfortunately, open housing came too late, after suburbia was largely built.  Across the United States, whites had kept African Americans out of most suburbs throughout most of the twentieth century.  By 1968, suburbs were labeled racially.  Once in place, these reputations were self-sustaining.  Desegregating them was an uphill struggle, a mount that we are still climbing.  Like anyone else, African Americans don’t want to live in a place where they aren’t wanted, and one way to deduce that they aren’t wanted is to note that no African Americans live there.  Today, just a little steering by realtors suffices to keep sundown suburbs nearly all-white.  Here is an example from Pennsylvania.  Whites and blacks refer to the suburbs across the Susquehanna River from Harrisburg as “the white shore.”  A man who grew up there wrote me:

I can tell you that there were (are?) sundown towns in Central Pennsylvania.  You were right about the “white shore.”  I have no objective proof at all.  However my mother grew up in Enola, and my uncle live in Camp Hill.  It was common knowledge that African-Americans would not be sold a house in those towns and those that surrounded them.  It was indeed a “white shore.”

By August 2002, when a new black employee moved to Harrisburg to take up her new job with the State of Pennsylvania, the pattern was in place.  “The realtor told me I could live on the west shore, but it’s really called ‘the white shore,’ so I’d probably be happier somewhere else.”  She bought in Harrisburg.  Such steering is illegal, but it goes on every day.
