Why I Need an iPad

I’m one of those who feel the iPad is the right tool for the job.

This is mostly meant as a reply to this blogthread. But it’s also more generally about my personal reaction to Apple’s iPad announcement.

Some background.

I’m an ethnographer and a teacher. I read a fair deal, write a lot of notes, and work in a variety of contexts. These days, I tend to spend a good amount of time in cafés and other public places where I like to work without being too isolated. I also commute using public transit, listen to lots of podcast, and create my own. I’m also very aural.

I’ve used a number of PDAs, over the years, from a Newton MessagePad 130 (1997) to a variety of PalmOS devices (until 2008). In fact, some people readily associated me with PDA use.

As soon as I learnt about the iPod touch, I needed one. As soon as I’ve heard about the SafariPad, I wanted one. I’ve been an intense ‘touch user since the iPhone OS 2.0 release and I’m a happy camper.

(A major reason I never bought an iPhone, apart from price, is that it requires a contract.)

In my experience, the ‘touch is the most appropriate device for all sorts of activities which are either part of an other activity (reading during a commute) or are simply too short in duration to constitute an actual “computer session.” You don’t “sit down to work at your ‘touch” the way you might sit in front of a laptop or desktop screen. This works great for “looking up stufff” or “checking email.” It also makes a lot of sense during commutes in crowded buses or metros.

In those cases, the iPod touch is almost ideal. Ubiquitous access to Internet would be nice, but that’s not a deal-breaker. Alternative text-input methods would help in some cases, but I do end up being about as fast on my ‘touch as I was with Graffiti on PalmOS.

For other tasks, I have a Mac mini. Sure, it’s limited. But it does the job. In fact, I have no intention of switching for another desktop and I even have an eMachines collecting dust (it’s too noisy to make a good server).

What I miss, though, is a laptop. I used an iBook G3 for several years and loved it. For a little while later, I was able to share a MacBook with somebody else and it was a wonderful experience. I even got to play with the OLPC XO for a few weeks. That one was not so pleasant an experience but it did give me a taste for netbooks. And it made me think about other types of iPhone-like devices. Especially in educational contexts. (As I mentioned, I’m a teacher)

I’ve been laptop-less for a while, now. And though my ‘touch replaces it in many contexts, there are still times when I’d really need a laptop. And these have to do with what I might call “mobile sessions.”

For instance: liveblogging a conference or meeting. I’ve used my ‘touch for this very purpose on a good number of occasions. But it gets rather uncomfortable, after a while, and it’s not very fast. A laptop is better for this, with a keyboard and a larger form factor. But the iPad will be even better because of lower risks of RSI. A related example: just imagine TweetDeck on iPad.

Possibly my favourite example of a context in which the iPad will be ideal: presentations. Even before learning about the prospect of getting iWork on a tablet, presentations were a context in which I really missed a laptop.

Sure, in most cases, these days, there’s a computer (usually a desktop running XP) hooked to a projector. You just need to download your presentation file from Slideshare, show it from Prezi, or transfer it through USB. No biggie.

But it’s not the extra steps which change everything. It’s the uncertainty. Even if it’s often unfounded, I usually get worried that something might just not work, along the way. The slides might not show the same way as you see it because something is missing on that computer or that computer is simply using a different version of the presentation software. In fact, that software is typically Microsoft PowerPoint which, while convenient, fits much less in my workflow than does Apple Keynote.

The other big thing about presentations is the “presenter mode,” allowing you to get more content than (or different content from) what the audience sees. In most contexts where I’ve used someone else’s computer to do a presentation, the projector was mirroring the computer’s screen, not using it as a different space. PowerPoint has this convenient “presenter view” but very rarely did I see it as an available option on “the computer in the room.” I wish I could use my ‘touch to drive presentations, which I could do if I installed software on that “computer in the room.” But it’s not something that is likely to happen, in most cases.

A MacBook solves all of these problems. and it’s an obvious use for laptops. But how, then, is the iPad better? Basically because of interface. Switching slides on a laptop isn’t hard, but it’s more awkward than we realize. Even before watching the demo of Keynote on the iPad, I could simply imagine the actual pleasure of flipping through slides using a touch interface. The fit is “natural.”

I sincerely think that Keynote on the iPad will change a number of things, for me. Including the way I teach.

Then, there’s reading.

Now, I’m not one of those people who just can’t read on a computer screen. In fact, I even grade assignments directly from the screen. But I must admit that online reading hasn’t been ideal, for me. I’ve read full books as PDF files or dedicated formats on PalmOS, but it wasn’t so much fun, in terms of the reading process. And I’ve used my ‘touch to read things through Stanza or ReadItLater. But it doesn’t work so well for longer reading sessions. Even in terms of holding the ‘touch, it’s not so obvious. And, what’s funny, even a laptop isn’t that ideal, for me, as a reading device. In a sense, this is when the keyboard “gets in the way.”

Sure, I could get a Kindle. I’m not a big fan of dedicated devices and, at least on paper, I find the Kindle a bit limited for my needs. Especially in terms of sources. I’d like to be able to use documents in a variety of formats and put them in a reading list, for extended reading sessions. No, not “curled up in bed.” But maybe lying down in a sofa without external lighting. Given my experience with the ‘touch, the iPad is very likely the ideal device for this.

Then, there’s the overall “multi-touch device” thing. People have already been quite creative with the small touchscreen on iPhones and ‘touches, I can just imagine what may be done with a larger screen. Lots has been said about differences in “screen real estate” in laptop or desktop screens. We all know it can make a big difference in terms of what you can display at the same time. In some cases, two screens isn’t even a luxury, for instance when you code and display a page at the same time (LaTeX, CSS…). Certainly, the same qualitative difference applies to multitouch devices. Probably even more so, since the display is also used for input. What Han found missing in the iPhone’s multitouch was the ability to use both hands. With the iPad, Han’s vision is finding its space.

Oh, sure, the iPad is very restricted. For instance, it’s easy to imagine how much more useful it’d be if it did support multitasking with third-party apps. And a front-facing camera is something I was expecting in the first iPhone. It would just make so much sense that a friend seems very disappointed by this lack of videoconferencing potential. But we’re probably talking about predetermined expectations, here. We’re comparing the iPad with something we had in mind.

Then, there’s the issue of the competition. Tablets have been released and some multitouch tablets have recently been announced. What makes the iPad better than these? Well, we could all get in the same OS wars as have been happening with laptops and desktops. In my case, the investment in applications, files, and expertise that I have made in a Mac ecosystem rendered my XP years relatively uncomfortable and me appreciate returning to the Mac. My iPod touch fits right in that context. Oh, sure, I could use it with a Windows machine, which is in fact what I did for the first several months. But the relationship between the iPhone OS and Mac OS X is such that using devices in those two systems is much more efficient, in terms of my own workflow, than I could get while using XP and iPhone OS. There are some technical dimensions to this, such as the integration between iCal and the iPhone OS Calendar, or even the filesystem. But I’m actually thinking more about the cognitive dimensions of recognizing some of the same interface elements. “Look and feel” isn’t just about shiny and “purty.” It’s about interactions between a human brain, a complex sensorimotor apparatus, and a machine. Things go more quickly when you don’t have to think too much about where some tools are, as you’re working.

So my reasons for wanting an iPad aren’t about being dazzled by a revolutionary device. They are about the right tool for the job.

Installing BuddyPress on a Webhost

[Jump here for more technical details.]

A few months ago, I installed BuddyPress on my Mac to try it out. It was a bit of an involved process, so I documented it:

WordPress MU, BuddyPress, and bbPress on Local Machine « Disparate.

More recently, I decided to get a webhost. Both to run some tests and, eventually, to build something useful. BuddyPress seems like a good way to go at it, especially since it’s improved a lot, in the past several months.

In fact, the installation process is much simpler, now, and I ran into some difficulties because I was following my own instructions (though adapting the process to my webhost). So a new blogpost may be in order. My previous one was very (possibly too) detailed. This one is much simpler, technically.

One thing to make clear is that BuddyPress is a set of plugins meant for WordPress µ (“WordPress MU,” “WPMU,” “WPµ”), the multi-user version of the WordPress blogging platform. BP is meant as a way to make WPµ more “social,” with such useful features as flexible profiles, user-to-user relationships, and forums (through bbPress, yet another one of those independent projects based on WordPress).

While BuddyPress depends on WPµ and does follow a blogging logic, I’m thinking about it as a social platform. Once I build it into something practical, I’ll probably use the blogging features but, in a way, it’s more of a tool to engage people in online social activities. BuddyPress probably doesn’t work as a way to “build a community” from scratch. But I think it can be quite useful as a way to engage members of an existing community, even if this engagement follows a blogger’s version of a Pareto distribution (which, hopefully, is dissociated from elitist principles).

But I digress, of course. This blogpost is more about the practical issue of adding a BuddyPress installation to a webhost.

Webhosts have come a long way, recently. Especially in terms of shared webhosting focused on LAMP (or PHP/MySQL, more specifically) for blogs and content-management. I don’t have any data on this, but it seems to me that a lot of people these days are relying on third-party webhosts instead of relying on their own servers when they want to build on their own blogging and content-management platforms. Of course, there’s a lot more people who prefer to use preexisting blog and content-management systems. For instance, it seems that there are more bloggers on WordPress.com than on other WordPress installations. And WP.com blogs probably represent a small number of people in comparison to the number of people who visit these blogs. So, in a way, those who run their own WordPress installations are a minority in the group of active WordPress bloggers which, itself, is a minority of blog visitors. Again, let’s hope this “power distribution” not a basis for elite theory!

Yes, another digression. I did tell you to skip, if you wanted the technical details!

I became part of the “self-hosted WordPress” community through a project on which I started work during the summer. It’s a website for an academic organization and I’m acting as the organization’s “Web Guru” (no, I didn’t choose the title). The site was already based on WordPress but I was rebuilding much of it in collaboration with the then-current “Digital Content Editor.” Through this project, I got to learn a lot about WordPress, themes, PHP, CSS, etc. And it was my first experience using a cPanel- (and Fantastico-)enabled webhost (BlueHost, at the time). It’s also how I decided to install WordPress on my local machine and did some amount of work from that machine.

But the local installation wasn’t an ideal solution for two reasons: a) I had to be in front of that local machine to work on this project; and b) it was much harder to show the results to the person with whom I was collaborating.

So, in the Fall, I decided to get my own staging server. After a few quick searches, I decided HostGator, partly because it was available on a monthly basis. Since this staging server was meant as a temporary solution, HG was close to ideal. It was easy to set up as a PayPal “subscription,” wasn’t that expensive (9$/month), had adequate support, and included everything that I needed at that point to install a current version of WordPress and play with theme files (after importing content from the original site). I’m really glad I made that decision because it made a number of things easier, including working from different computers, and sending links to get feedback.

While monthly HostGator fees were reasonable, it was still a more expensive proposition than what I had in mind for a longer-term solution. So, recently, a few weeks after releasing the new version of the organization’s website, I decided to cancel my HostGator subscription. A decision I made without any regret or bad feeling. HostGator was good to me. It’s just that I didn’t have any reason to keep that account or to do anything major with the domain name I was using on HG.

Though only a few weeks elapsed since I canceled that account, I didn’t immediately set out to transition to a new webhost. I didn’t go from HostGator to another webhost.

But having my own webhost still remained at the back of my mind as something which might be useful. For instance, while not really making a staging server necessary, a new phase in the academic website project brought up a sandboxing idea. Also, I went to a “WordPress Montreal” meeting and got to think about further WordPress development/deployment, including using BuddyPress for my own needs (both as my own project and as a way to build my own knowledge of the platform) instead of it being part of an organization’s project. I was also thinking about other interesting platforms which necessitate a webhost.

(More on these other platforms at a later point in time. Bottom line is, I’m happy with the prospects.)

So I wanted a new webhost. I set out to do some comparison shopping, as I’m wont to do. In my (allegedly limited) experience, finding the ideal webhost is particularly difficult. For one thing, search results are cluttered with a variety of “unuseful” things such as rants, advertising, and limited comparisons. And it’s actually not that easy to give a new webhost a try. For one thing, these hosting companies don’t necessarily have the most liberal refund policies you could imagine. And, switching a domain name between different hosts and registrars is a complicated process through which a name may remain “hostage.” Had I realized what was involved, I might have used a domain name to which I have no attachment or actually eschewed the whole domain transition and just try the webhost without a dedicated domain name.

Doh!
Live and learn. I sure do. Loving almost every minute of it.

At any rate, I had a relatively hard time finding my webhost.

I really didn’t need “bells and whistles.” For instance, all the AdSense, shopping cart, and other business-oriented features which seem to be publicized by most webhosting companies have no interest, to me.

I didn’t even care so much about absolute degree of reliability or speed. What I’m to do with this host is fairly basic stuff. The core idea is to use my own host to bypass some limitations. For instance, WordPress.com doesn’t allow for plugins yet most of the WordPress fun has to do with plugins.

I did want an “unlimited” host, as much as possible. Not because expect to have huge resource needs but I just didn’t want to have to monitor bandwidth.

I thought that my needs would be basic enough that any cPanel-enabled webhost would fit. As much as I could see, I needed FTP access to something which had PHP 5 and MySQL 5. I expected to install things myself, without use of the webhost’s scripts but I also thought the host would have some useful scripts. Although I had already registered the domain I wanted to use (through Name.com), I thought it might be useful to have a free domain in the webhosting package. Not that domain names are expensive, it’s more of a matter of convenience in terms of payment or setup.

I ended up with FatCow. But, honestly, I’d probably go with a different host if I were to start over (which I may do with another project).

I paid 88$ for two years of “unlimited” hosting, which is quite reasonable. And, on paper, FatCow has everything I need (and I bunch of things I don’t need). The missing parts aren’t anything major but have to do with minor annoyances. In other words, no real deal-breaker, here. But there’s a few things I wish I had realized before I committed on FatCow with a domain name I actually want to use.

Something which was almost a deal-breaker for me is the fact that FatCow requires payment for any additional subdomain. And these aren’t cheap: the minimum is 5$/month for five subdomains, up to 25$/month for unlimited subdomains! Even at a “regular” price of 88$/year for the basic webhosting plan, the “unlimited subdomains” feature (included in some webhosting plans elsewhere) is more than three times more expensive than the core plan.

As I don’t absolutely need extra subdomains, this is mostly a minor irritant. But it’s one reason I’ll probably be using another webhost for other projects.

Other issues with FatCow are probably not enough to motivate a switch.

For instance, the PHP version installed on FatCow (5.2.1) is a few minor releases behind the one needed by some interesting web applications. No biggie, especially if PHP is updated in a relatively reasonable timeframe. But still makes for a slight frustration.

The MySQL version seems recent enough, but it uses non-standard tools to manage it, which makes for some confusion. Attempting to create some MySQL databases with obvious names (say “wordpress”) fails because the database allegedly exists (even though it doesn’t show up in the MySQL administration). In the same vein, the URL of the MySQL is <username>.fatcowmysql.com instead of localhost as most installers seem to expect. Easy to handle once you realize it, but it makes for some confusion.

In terms of Fantastico-like simplified installation of webapps, FatCow uses InstallCentral, which looks like it might be its own Fantastico replacement. InstallCentral is decent enough as an installation tool and FatCow does provide for some of the most popular blog and CMS platforms. But, in some cases, the application version installed by FatCow is old enough (2005!)  that it requires multiple upgrades to get to a current version. Compared to other installation tools, FatCow’s InstallCentral doesn’t seem really efficient at keeping track of installed and released versions.

Something which is partly a neat feature and partly a potential issue is the way FatCow handles Apache-related security. This isn’t something which is so clear to me, so I might be wrong.

Accounts on both BlueHost and HostGator include a public_html directory where all sorts of things go, especially if they’re related to publicly-accessible content. This directory serves as the website’s root, so one expects content to be available there. The “index.html” or “index.php” file in this directory serves as the website’s frontpage. It’s fairly obvious, but it does require that one would understand a few things about webservers. FatCow doesn’t seem to create a public_html directory in a user’s server space. Or, more accurately, it seems that the root directory (aka ‘/’) is in fact public_html. In this sense, a user doesn’t have to think about which directory to use to share things on the Web. But it also means that some higher-level directories aren’t available. I’ve already run into some issues with this and I’ll probably be looking for a workaround. I’m assuming there’s one. But it’s sometimes easier to use generally-applicable advice than to find a custom solution.

Further, in terms of access control… It seems that webapps typically make use of diverse directories and .htaccess files to manage some forms of access controls. Unix-style file permissions are also involved but the kind of access needed for a web app is somewhat different from the “User/Group/All” of Unix filesystems. AFAICT, FatCow does support those .htaccess files. But it has its own tools for building them. That can be a neat feature, as it makes it easier, for instance, to password-protect some directories. But it could also be the source of some confusion.

There are other issues I have with FatCow, but it’s probably enough for now.

So… On to the installation process… 😉

It only takes a few minutes and is rather straightforward. This is the most verbose version of that process you could imagine…

Surprised? 😎

Disclaimer: I’m mostly documenting how I did it and there are some things about which I’m unclear. So it may not work for you. If it doesn’t, I may be able to help but I provide no guarantee that I will. I’m an anthropologist, not a Web development expert.

As always, YMMV.

A few instructions here are specific to FatCow, but the general process is probably valid on other hosts.

I’m presenting things in a sequence which should make sense. I used a slightly different order myself, but I think this one should still work. (If it doesn’t, drop me a comment!)

In these instructions, straight quotes (“”) are used to isolate elements from the rest of the text. They shouldn’t be typed or pasted.

I use “example.com” to refer to the domain on which the installation is done. In my case, it’s the domain name I transfered to FatCow from another registrar but it could probably be done without a dedicated domain (in which case it would be “<username>.fatcow.com” where “<username>” is your FatCow username).

I started with creating a MySQL database for WordPress MU. FatCow does have phpMyAdmin but the default tool in the cPanel is labeled “Manage MySQL.” It’s slightly easier to use for creating new databases than phpMyAdmin because it creates the database and initial user (with confirmed password) in a single, easy-to-understand dialog box.

So I created that new database, user, and password, noting down this information. Since that password appears in clear text at some point and can easily be changed through the same interface, I used one which was easy to remember but wasn’t one I use elsewhere.
Then, I dowloaded the following files to my local machine in order to upload them to my FatCow server space. The upload can be done through either FTP or FatCow’s FileManager. I tend to prefer FTP (via CyberDuck on the Mac or FileZilla on PC). But the FileManager does allow for easy uploads.
(Wish it could be more direct, using the HTTP links directly instead of downloading to upload. But I haven’t found a way to do it through either FTP or the FileManager.)
At any rate, here are the four files I transfered to my FatCow space, using .zip when there’s a choice (the .tar.gz “tarball” versions also work but require a couple of extra steps).
  1. WordPress MU (wordpress-mu-2.9.1.1.zip, in my case)
  2. Buddymatic (buddymatic.0.9.6.3.1.zip, in my case)
  3. EarlyMorning (only one version, it seems)
  4. EarlyMorning-BP (only one version, it seems)

Only the WordPress MU archive is needed to install BuddyPress. The last three files are needed for EarlyMorning, a BuddyPress theme that I found particularly neat. It’s perfectly possible to install BuddyPress without this specific theme. (Although, doing so, you need to install a BuddyPress-compatible theme, if only by moving some folders to make the default theme available, as I explained in point 15 in that previous tutorial.) Buddymatic itself is a theme framework which includes some child themes, so you don’t need to install EarlyMorning. But installing it is easy enough that I’m adding instructions related to that theme.

These files can be uploaded anywhere in my FatCow space. I uploaded them to a kind of test/upload directory, just to make it clear, for me.

A major FatCow idiosyncrasy is its FileManager (actually called “FileManager Beta” in the documentation but showing up as “FileManager” in the cPanel). From my experience with both BlueHost and HostGator (two well-known webhosting companies), I can say that FC’s FileManager is quite limited. One thing it doesn’t do is uncompress archives. So I have to resort to the “Archive Gateway,” which is surprisingly slow and cumbersome.

At any rate, I used that Archive Gateway to uncompress the four files. WordPress µ first (in the root directory or “/”), then both Buddymatic and EarlyMorning in “/wordpress-mu/wp-content/themes” (you can chose the output directory for zip and tar files), and finally EarlyMorning-BP (anywhere, individual files are moved later). To uncompress each file, select it in the dropdown menu (it can be located in any subdirectory, Archive Gateway looks everywhere), add the output directory in the appropriate field in the case of Buddymatic or EarlyMorning, and press “Extract/Uncompress”. Wait to see a message (in green) at the top of the window saying that the file has been uncompressed successfully.

Then, in the FileManager, the contents of the EarlyMorning-BP directory have to be moved to “/wordpress-mu/wp-content/themes/earlymorning”. (Thought they could be uncompressed there directly, but it created an extra folder.) To move those files in the FileManager, I browse to that earlymorning-bp directory, click on the checkbox to select all, click on the “Move” button (fourth from right, marked with a blue folder), and add the output path: /wordpress-mu/wp-content/themes/earlymorning

These files are tweaks to make the EarlyMorning theme work with BuddyPress.

Then, I had to change two files, through the FileManager (it could also be done with an FTP client).

One change is to EarlyMorning’s style.css:

/wordpress-mu/wp-content/themes/earlymorning/style.css

There, “Template: thematic” has to be changed to “Template: buddymatic” (so, “the” should be changed to “buddy”).

That change is needed because the EarlyMorning theme is a child theme of the “Thematic” WordPress parent theme. Buddymatic is a BuddyPress-savvy version of Thematic and this changes the child-parent relation from Thematic to Buddymatic.

The other change is in the Buddymatic “extensions”:

/wordpress-mu/wp-content/themes/buddymatic/library/extensions/buddypress_extensions.php

There, on line 39, “$bp->root_domain” should be changed to “bp_root_domain()”.

This change is needed because of something I’d consider a bug but that a commenter on another blog was kind enough to troubleshoot. Without this modification, the login button in BuddyPress wasn’t working because it was going to the website’s root (example.com/wp-login.php) instead of the WPµ installation (example.com/wordpress-mu/wp-login.php). I was quite happy to find this workaround but I’m not completely clear on the reason it works.

Then, something I did which might not be needed is to rename the “wordpress-mu” directory. Without that change, the BuddyPress installation would sit at “example.com/wordpress-mu,” which seems a bit cryptic for users. In my mind, “example.com/<name>,” where “<name>” is something meaningful like “social” or “community” works well enough for my needs. Because FatCow charges for subdomains, the “<name>.example.com” option would be costly.

(Of course, WPµ and BuddyPress could be installed in the site’s root and the frontpage for “example.com” could be the BuddyPress frontpage. But since I think of BuddyPress as an add-on to a more complete site, it seems better to have it as a level lower in the site’s hierarchy.)

With all of this done, the actual WPµ installation process can begin.

The first thing is to browse to that directory in which WPµ resides, either “example.com/wordpress-mu” or “example.com/<name>” with the “<name>” you chose. You’re then presented with the WordPress µ Installation screen.

Since FatCow charges for subdomains, it’s important to choose the following option: “Sub-directories (like example.com/blog1).” It’s actually by selecting the other option that I realized that FatCow restricted subdomains.

The Database Name, username and password are the ones you created initially with Manage MySQL. If you forgot that password, you can actually change it with that same tool.

An important FatCow-specific point, here, is that “Database Host” should be “<username>.fatcowmysql.com” (where “<username>” is your FatCow username). In my experience, other webhosts use “localhost” and WPµ defaults to that.

You’re asked to give a name to your blog. In a way, though, if you think of BuddyPress as more of a platform than a blogging system, that name should be rather general. As you’re installing “WordPress Multi-User,” you’ll be able to create many blogs with more specific names, if you want. But the name you’re entering here is for BuddyPress as a whole. As with <name> in “example.com/<name>” (instead of “example.com/wordpress-mu”), it’s a matter of personal opinion.

Something I noticed with the EarlyMorning theme is that it’s a good idea to keep the main blog’s name relatively short. I used thirteen characters and it seemed to fit quite well.

Once you’re done filling in this page, WPµ is installed in a flash. You’re then presented with some information about your installation. It’s probably a good idea to note down some of that information, including the full paths to your installation and the administrator’s password.

But the first thing you should do, as soon as you log in with “admin” as username and the password provided, is probably to the change that administrator password. (In fact, it seems that a frequent advice in the WordPress community is to create a new administrator user account, with a different username than “admin,” and delete the “admin” account. Given some security issues with WordPress in the past, it seems like a good piece of advice. But I won’t describe it here. I did do it in my installation and it’s quite easy to do in WPµ.

Then, you should probably enable plugins here:

example.com/<name>/wp-admin/wpmu-options.php#menu

(From what I understand, it might be possible to install BuddyPress without enabling plugins, since you’re logged in as the administrator, but it still makes sense to enable them and it happens to be what I did.)

You can also change a few other options, but these can be set at another point.

One option which is probably useful, is this one:

Allow new registrations Disabled
Enabled. Blogs and user accounts can be created.
Only user account can be created.

Obviously, it’s not necessary. But in the interest of opening up the BuddyPress to the wider world without worrying too much about a proliferation of blogs, it might make sense. You may end up with some fake user accounts, but that shouldn’t be a difficult problem to solve.

Now comes the installation of the BuddyPress plugin itself. You can do so by going here:

example.com/<name>/wp-admin/plugin-install.php

And do a search for “BuddyPress” as a term. The plugin you want was authored by “The BuddyPress Community.” (In my case, version 1.1.3.) Click the “Install” link to bring up the installation dialog, then click “Install Now” to actually install the plugin.

Once the install is done, click the “Activate” link to complete the basic BuddyPress installation.

You now have a working installation of BuddyPress but the BuddyPress-savvy EarlyMorning isn’t enabled. So you need to go to “example.com/<name>/wp-admin/wpmu-themes.php” to enable both Buddymatic and EarlyMorning. You should then go to “example.com/<name>/wp-admin/themes.php” to activate the EarlyMorning theme.

Something which tripped me up because it’s now much easier than before is that forums (provided through bbPress) are now, literally, a one-click install. If you go here:

example.com/<name>/wp-admin/admin.php?page=bb-forums-setup

You can set up a new bbPress install (“Set up a new bbPress installation”) and everything will work wonderfully in terms of having forums fully integrated in BuddyPress. It’s so seamless that I wasn’t completely sure it had worked.

Besides this, I’d advise that you set up a few widgets for the BuddyPress frontpage. You do so through an easy-to-use drag-and-drop interface here:

example.com/<name>/wp-admin/widgets.php

I especially advise you to add the Twitter RSS widget because it seems to me to fit right in. If I’m not mistaken, the EarlyMorning theme contains specific elements to make this widget look good.

After that, you can just have fun with your new BuddyPress installation. The first thing I did was to register a new user. To do so, I logged out of my admin account,  and clicked on the Sign Up button. Since I “allow new registrations,” it’s a very simple process. In fact, this is one place where I think that BuddyPress shines. Something I didn’t explain is that you can add a series of fields for that registration and the user profile which goes with it.

The whole process really shouldn’t take very long. In fact, the longest parts have probably to do with waiting for Archive Gateway.

The rest is “merely” to get people involved in your BuddyPress installation. It can happen relatively easily, if you already have a group of people trying to do things together online. But it can be much more complicated than any software installation process… 😉

Homeroasting and Coffee Geekness

I’m a coffee geek. By which I mean that I have a geeky attitude to coffee. I’m passionate about the crafts and arts of coffee making, I seek coffee-related knowledge wherever I can find it, I can talk about coffee until people’s eyes glaze over (which happens more quickly than I’d guess possible), and I even dream about coffee gadgets. I’m not a typical gadget freak, as far as geek culture goes, but coffee is one area where I may invest in some gadgetry.

Perhaps my most visible acts of coffee geekery came in the form of updates I posted through diverse platforms about my home coffee brewing experiences. Did it from February to July. These posts contained cryptic details about diverse measurements, including water temperature and index of refraction. It probably contributed to people’s awareness of my coffee geek identity, which itself has been the source of fun things like a friend bringing me back coffee from Ethiopia.

But I digress, a bit. This is both about coffee geekness in general and about homeroasting in particular.

See, I bought myself this Hearthware i-Roast 2 dedicated homeroasting device. And I’m dreaming about coffee again.

Been homeroasting since December 2002, at the time I moved to Moncton, New Brunswick and was lucky enough to get in touch with Terry Montague of Down Esst Coffee.

Though I had been wishing to homeroast for a while before that and had become an intense coffee-lover fifteen years prior to contacting him, Terry is the one who enabled me to start roasting green coffee beans at home. He procured me a popcorn popper, sourced me some quality green beans, gave me some advice. And off I was.

Homeroasting is remarkably easy. And it makes a huge difference in one’s appreciation of coffee. People in the coffee industry, especially baristas and professional roasters, tend to talk about the “channel” going from the farmer to the “consumer.” In some ways, homeroasting gets the coffee-lover a few steps closer to the farmer, both by eliminating a few intermediaries in the channel and by making coffee into much less of a commodity. Once you’ve spent some time smelling the fumes emanated by different coffee varietals and looking carefully at individual beans, you can’t help but get a deeper appreciation for the farmer’s and even the picker’s work. When you roast 150g or less at a time, every coffee bean seems much more valuable. Further, as you experiment with different beans and roast profiles, you get to experience coffee in all of its splendour.

A popcorn popper may sound like a crude way to roast coffee. And it might be. Naysayers may be right in their appraisal of poppers as a coffee roasting method. You’re restricted in different ways and it seems impossible to produce exquisite coffee. But having roasted with a popper for seven years, I can say that my poppers gave me some of my most memorable coffee experiences. Including some of the most pleasant ones, like this organic Sumatra from Theta Ridge Coffee that I roasted in my campus appartment at IUSB and brewed using my beloved Brikka.

Over the years, I’ve roasted a large variety of coffee beans. I typically buy a pound each of three or four varietals and experiment with them for a while.

Mostly because I’ve been moving around quite a bit, I’ve been buying green coffee beans from a rather large variety of places. I try to buy them locally, as much as possible (those beans have travelled far enough and I’ve had enough problems with courier companies). But I did participate in a few mail orders or got beans shipped to me for some reason or another. Sourcing green coffee beans has almost been part of my routine in those different places where I’ve been living since 2002: Moncton, Montreal, Fredericton, South Bend, Northampton, Brockton, Cambridge, and Austin. Off the top of my head, I’ve sourced beans from:

  1. Down East
  2. Toi, moi & café
  3. Brûlerie Saint-Denis
  4. Brûlerie des quatre vents
  5. Terra
  6. Theta Ridge
  7. Dean’s Beans
  8. Green Beanery
  9. Cuvée
  10. Fair Bean
  11. Sweet Maria’s
  12. Evergreen Coffee
  13. Mon café vert
  14. Café-Vrac
  15. Roastmasters
  16. Santropol

And probably a few other places, including this one place in Ethiopia where my friend Erin bought some.

So, over the years, I got beans from a rather large array of places and from a wide range of regional varietals.

I rapidly started blending freshly-roasted beans. Typically, I would start a blend by roasting three batches in a row. I would taste some as “single origin” (coffee made from a single bean varietal, usually from the same farm or estate), shortly after roasting. But, typically, I would mix my batches of freshly roasted coffee to produce a main blend. I would then add fresh batches after a few days to fine-tune the blend to satisfy my needs and enhance my “palate” (my ability to pick up different flavours and aromas).

Once the quantity of green beans in a particular bag would fall below an amount I can reasonably roast as a full batch (minimum around 100g), I would put those green beans in a pre-roast blend, typically in a specially-marked ziplock bag. Roasting this blend would usually be a way for me to add some complexity to my roasted blends.

And complexity I got. Lots of diverse flavours and aromas. Different things to “write home about.”

But I was obviously limited in what I could do with my poppers. The only real controls that I had in homeroasting, apart from blending, consisted in the bean quantity and roasting time. Ambient temperature was clearly a factor, but not one over which I was able to exercise much control. Especially since I frequently ended up roasting outside, so as to not incommodate people with fumes, noise, and chaff. The few homeroast batches which didn’t work probably failed because of low ambient temperature.

One reason I stuck with poppers for so long was that I had heard that dedicated roasters weren’t that durable. I’ve probably used three or four different hot air popcorn poppers, over the years. Eventually, they just stop working, when you use them for coffee beans. As I’d buy them at garage sales and Salvation Army stores for 3-4$, replacing them didn’t feel like such a financially difficult thing to do, though finding them could occasionally be a challenge. Money was also an issue. Though homeroasting was important for me, I wasn’t ready to pay around 200$ for an entry-level dedicated roaster. I was thinking about saving money for a Behmor 1600, which offers several advantages over other roasters. But I finally gave in and bought my i-Roast as a kind of holiday gift to myself.

One broad reason is that my financial situation has improved since I started a kind of partial professional reorientation (PPR). I have a blogpost in mind about this PPR, and I’ll probably write it soon. But this post isn’t about my PPR.

Although, the series of events which led to my purchase does relate to my PPR, somehow.

See, the beans I (indirectly) got from Roastmasters came from a friend who bought a Behmor to roast cocoa beans. The green coffee beans came with the roaster but my friend didn’t want to roast coffee in his brand new Behmor, to avoid the risk of coffee oils and flavours getting into his chocolate. My friend asked me to roast some of these beans for his housemates (he’s not that intensely into coffee, himself). When I went to drop some homeroasted coffee by the Station C co-working space where he spends some of his time, my friend was discussing a project with Duncan Moore, whom I had met a few times but with whom I had had few interactions. The three of us had what we considered a very fruitful yet very short conversation. Later on, I got to do a small but fun project with Duncan. And I decided to invest that money into coffee.

A homeroaster seemed like the most appropriate investment. The Behmor was still out of reach but the i-Roast seemed like a reasonable purchase. Especially if I could buy it used.

But I was also thinking about buying it new, as long as I could get it quickly. It took me several years to make a decision about this purchase but, once I made it, I wanted something as close to “instant gratification” as possible. In some ways, the i-Roast was my equivalent to Little Mrs Sommers‘s “pair of silk stockings.”

At the time, Mon café vert seemed like the only place where I could buy a new i-Roast. I tried several times to reach them to no avail. As I was in the Mile-End as I decided to make that purchase, I went to Caffè in Gamba, both to use the WiFi signal and to check if, by any chance, they might not have started selling roasters. They didn’t, of course, homeroasters isn’t mainstream enough. But, as I was there, I saw the Hario Ceramic Coffee Mill Skerton, a “hand-cranked” coffee grinder about which I had read some rather positive reviews.

For the past few years, I had been using a Bodum Antigua conical burr electric coffee grinder. This grinder was doing the job, but maybe because of “wear and tear,” it started taking a lot longer to grind a small amount of coffee. The grind took so long, at some points, that the grounds were warm to the touch and it seemed like the grinder’s motor was itself heating.

So I started dreaming about the Baratza Vario, a kind of prosumer electric grinder which seemed like the ideal machine for someone who uses diverse coffee making methods. The Vario is rather expensive and seemed like overkill, for my current coffee setup. But I was lusting over it and, yes, dreaming about it.

One day, maybe, I’ll be able to afford a Vario.

In the meantime, and more reasonably, I had been thinking about “Turkish-style mills.” A friend lent me a box-type manual mill at some point and I did find it produced a nice grind, but it wasn’t that convenient for me, partly because the coffee drops into a small drawer which rapidly gets full. A handmill seemed somehow more convenient and there are some generic models which are sold in different parts of the World, especially in the Arab World. So I got the impression that I might be able to find handmills locally and started looking for them all over the place, enquiring at diverse stores and asking friends who have used those mills in the past. Of course, they can be purchased online. But they end up being relatively expensive and my manual experience wasn’t so positive as to convince me to spend so much money on one.

The Skerton was another story. It was much more convenient than a box-type manual mill. And, at Gamba, it was inexpensive enough for me to purchase it on the spot. I don’t tend to do this very often so I did feel strange about such an impulse purchase. But I certainly don’t regret it.

Especially since it complements my other purchases.

So, going to the i-Roast.

Over the years, I had been looking for the i-Roast and Behmor at most of the obvious sites where one might buy used devices like these. eBay, Craig’s List, Kijiji… As a matter of fact, I had seen an i-Roast on one of these, but I was still hesitating. Not exactly sure why, but it probably had to do with the fact that these homeroasters aren’t necessarily that durable and I couldn’t see how old this particular i-Roast was.

I eventually called to find out, after taking my decision to get an i-Roast. Turns out that it’s still under warranty, is in great condition, and was being sold by a very interesting (and clearly trustworthy) alto singer who happens to sing with a friend of mine who is also a local beer homebrewer. The same day I bought the roaster, I went to the cocoa-roasting friend’s place and saw a Behmor for the first time. And I tasted some really nice homemade chocolate. And met other interesting people including a couple that I saw, again, while taking the bus after purchasing the roaster.

The series of coincidences in that whole situation impressed me in a sense of awe. Not out of some strange superstition or other folk belief. But different things are all neatly packaged in a way that most of my life isn’t. Nothing weird about this. The packaging is easy to explain and mostly comes from my own perception. The effect is still there that it all fits.

And the i-Roast 2 itself fits, too.

It’s clearly not the ultimate coffee geek’s ideal roaster. But I get the impression it could become so. In fact, one reason I hesitated to buy the i-Roast 2 is that I was wondering if Hearthware might be coming out with the i-Roast 3, in the not-so-distant future.

I’m guessing that Hearthware might be getting ready to release a new roaster. I’m using unreliable information, but it’s still an educated guess. So, apparently…

I could just imagine what the i-Roast 3 might be. As I’m likely to get, I have a number of crazy ideas.

One “killer feature” actually relates both to the differences between the i-Roast and i-Roast 2 as well as to the geek factor behind homeroasting: roast profiles as computer files. Yes, I know, it sounds crazy. And, somehow, it’s quite unlikely that Hearthware would add such a feature on an entry-level machine. But I seriously think it’d make the roaster much closer to a roasting geek’s ultimate machine.

For one thing, programming a roast profile on the i-Roast is notoriously awkward. Sure, you get used to it. But it’s clearly suboptimal. And one major improvement of the i-Roast 2 over the original i-Roast is that the original version didn’t maintain profiles if you unplugged it. The next step, in my mind, would be to have some way to transfer a profile from a computer to the roaster, say via a slot for SD cards or even a USB port.

What this would open isn’t only the convenience of saving profiles, but actually a way to share them with fellow homeroasters. Since a lot in geek culture has to do with sharing information, a neat effect could come out of shareable roast profiles. In fact, when I looked for example roast profiles, I found forum threads, guides, and incredibly elaborate experiments. Eventually, it might be possible to exchange roasting profiles relating to coffee beans from the same shipment and compare roasting. Given the well-known effects of getting a group of people using online tools to share information, this could greatly improve the state of homeroasting and even make it break out of the very small niche in which it currently sits.

Of course, there are many problems with that approach, including things as trivial as voltage differences as well as bigger issues such as noise levels:

But I’m still dreaming about such things.

In fact, I go a few steps further. A roaster which could somehow connect to a computer might also be used to track data about temperature and voltage. In my own experiments with the i-Roast 2, I’ve been logging temperatures at 15 second intervals along with information about roast profile, quantity of beans, etc. It may sound extreme but it already helped me achieve a result I wanted to achieve. And it’d be precisely the kind of information I would like to share with other homeroasters, eventually building a community of practice.

Nothing but geekness, of course. Shall the geek inherit the Earth?

Personal Devices

Still thinking about touch devices, such as the iPod touch and the rumoured “Apple Tablet.”

Thinking out loud. Rambling even more crazily than usual.

Something important about those devices is the need for a real “Personal Digital Assistant.” I put PDAs as a keyword for my previous post because I do use the iPod touch like I was using my PalmOS and even NewtonOS devices. But there’s more to it than that, especially if you think about cloud computing and speech technologies.
I mentioned speech recognition in that previous post. SR tends to be a pipedream of the computing world. Despite all the hopes put into realtime dictation, it still hasn’t taken off in a big way. One reason might be that it’s still somewhat cumbersome to use, in current incarnations. Another reason is that it’s relatively expensive as a standalone product which requires some getting used to. But I get the impression that another set of reasons has to do with the fact that it’s mostly fitting on a personal device. Partly because it needs to be trained. But also because voice itself is a personal thing.

Cloud computing also takes a new meaning with a truly personal device. It’s no surprise that there are so many offerings with some sort of cloud computing feature in the App Store. Not only do Apple’s touch devices have limited file storage space but the notion of accessing your files in the cloud go well with a personal device.
So, what’s the optimal personal device? I’d say that Apple’s touch devices are getting close to it but that there’s room for improvement.

Some perspective…

Originally, the PC was supposed to be a “personal” computer. But the distinction was mostly with mainframes. PCs may be owned by a given person, but they’re not so tied to that person, especially given the fact that they’re often used in a single context (office or home, say). A given desktop PC can be important in someone’s life, but it’s not always present like a personal device should be. What’s funny is that “personal computers” became somewhat more “personal” with the ‘Net and networking in general. Each computer had a name, etc. But those machines remained somewhat impersonal. In many cases, even when there are multiple profiles on the same machine, it’s not so safe to assume who the current user of the machine is at any given point.

On paper, the laptop could have been that “personal device” I’m thinking about. People may share a desktop computer but they usually don’t share their laptop, unless it’s mostly used like a desktop computer. The laptop being relatively easy to carry, it’s common for people to bring one back and forth between different sites: work, home, café, school… Sounds tautological, as this is what laptops are supposed to be. But the point I’m thinking about is that these are still distinct sites where some sort of desk or table is usually available. People may use laptops on their actual laps, but the form factor is still closer to a portable desktop computer than to the kind of personal device I have in mind.

Then, we can go all the way to “wearable computing.” There’s been some hype about wearable computers but it has yet to really be part of our daily lives. Partly for technical reasons but partly because it may not really be what people need.

The original PDAs (especially those on NewtonOS and PalmOS) were getting closer to what people might need, as personal devices. The term “personal digital assistant” seemed to encapsulate what was needed. But, for several reasons, PDAs have been having a hard time. Maybe there wasn’t a killer app for PDAs, outside of “vertical markets.” Maybe the stylus was the problem. Maybe the screen size and bulk of the device weren’t getting to the exact points where people needed them. I was still using a PalmOS device in mid-2008 and it felt like I was among the last PDA users.
One point was that PDAs had been replaced by “smartphones.” After a certain point, most devices running PalmOS were actually phones. RIM’s Blackberry succeeded in a certain niche (let’s use the vague term “professionals”) and is even beginning to expand out of it. And devices using other OSes have had their importance. It may not have been the revolution some readers of Pen Computing might have expected, but the smartphone has been a more successful “personal device” than the original PDAs.

It’s easy to broaden our focus from smartphones and think about cellphones in general. If the 3.3B figure can be trusted, cellphones may already be outnumbering desktop and laptop computers by 3:1. And cellphones really are personal. You bring them everywhere; you don’t need any kind of surface to use them; phone communication actually does seem to be a killer app, even after all this time; there are cellphones in just about any price range; cellphone carriers outside of Canada and the US are offering plans which are relatively reasonable; despite some variation, cellphones are rather similar from one manufacturer to the next… In short, cellphones already were personal devices, even before the smartphone category really emerged.

What did smartphones add? Basically, a few PDA/PIM features and some form of Internet access or, at least, some form of email. “Whoa! Impressive!”

Actually, some PIM features were already available on most cellphones and Internet access from a smartphone is in continuity with SMS and data on regular cellphones.

What did Apple’s touch devices add which was so compelling? Maybe not so much, apart from the multitouch interface, a few games, and integration with desktop/laptop computers. Even then, most of these changes were an evolution over the basic smartphone concept. Still, it seems to have worked as a way to open up personal devices to some new dimensions. People now use the iPhone (or some other multitouch smartphone which came out after the iPhone) as a single device to do all sorts of things. Around the World, multitouch smartphones are still much further from being ubiquitous than are cellphones in general. But we could say that these devices have brought the personal device idea to a new phase. At least, one can say that they’re much more exciting than the other personal computing devices.

But what’s next for personal devices?

Any set of buzzphrases. Cloud computing, speech recognition, social media…

These things can all come together, now. The “cloud” is mostly ready and personal devices make cloud computing more interesting because they’re “always-on,” are almost-wearable, have batteries lasting just about long enough, already serve to keep some important personal data, and are usually single-user.

Speech recognition could go well with those voice-enabled personal devices. For one thing, they already have sound input. And, by this time, people are used to seeing others “talk to themselves” as cellphones are so common. Plus, voice recognition is already understood as a kind of security feature. And, despite their popularity, these devices could use a further killer app, especially in terms of text entry and processing. Some of these devices already have voice control and it’s not so much of a stretch to imagine them having what’s needed for continuous speech recognition.

In terms of getting things onto the device, I’m also thinking about such editing features as a universal rich-text editor (à la TinyMCE), predictive text, macros, better access to calendar/contact data, ubiquitous Web history, multiple pasteboards, data detectors, Automator-like processing, etc. All sorts of things which should come from OS-level features.

“Social media” may seem like too broad a category. In many ways, those devices already take part in social networking, user-generated content, and microblogging, to name a few areas of social media. But what about a unified personal profile based on the device instead of the usual authentication method? Yes, all sorts of security issues. But aren’t people unconcerned about security in the case of social media? Twitter accounts are being hacked left and right yet Twitter doesn’t seem to suffer much. And there could be added security features on a personal device which is meant to really integrate social media. Some current personal devices already work well as a way to keep login credentials to multiple sites. The next step, there, would be to integrate all those social media services into the device itself. We maybe waiting for OpenSocial, OpenID, OAuth, Facebook Connect, Google Connect, and all sorts of APIs to bring us to an easier “social media workflow.” But a personal device could simplify the “social media workflow” even further, with just a few OS-based tweaks.

Unlike my previous, I’m not holding my breath for some specific event which will bring us the ultimate personal device. After all, this is just a new version of my ultimate handheld device blogpost. But, this time, I was focusing on what it means for a device to be “personal.” It’s even more of a drafty draft than my blogposts usually have been ever since I decided to really RERO.

So be it.

Speculating on Apple's Touch Strategy

This is mere speculation on my part, based on some rumours.

I’m quite sure that Apple will come up with a video-enabled iPod touch on September 9, along with iTunes 9 (which should have a few new “social networking” features). This part is pretty clear from most rumour sites.

AppleInsider | Sources: Apple to unveil new iPod lineup on September 9.

Progressively, Apple will be adopting a new approach to marketing its touch devices. Away from the “poorperson’s iPhone” and into the “tiny but capable computer” domain. Because the 9/9 event is supposed to be about music, one might guess that there will be a cool new feature or two relating to music. Maybe lyrics display, karaoke mode, or whatever else. Something which will simultaneously be added to the iPhone but would remind people that the iPod touch is part of the iPod family. Apple has already been marketing the iPod touch as a gaming platform, so it’s not a radical shift. But I’d say the strategy is to make Apple’s touch devices increasingly more attractive, without cannibalizing sales in the MacBook family.

Now, I really don’t expect Apple to even announce the so-called “Tablet Mac” in September. I’m not even that convinced that the other devices Apple is preparing for expansion of its touch devices lineup will be that close to the “tablet” idea. But it seems rather clear, to me, that Apple should eventually come up with other devices in this category. Many rumours point to the same basic notion, that Apple is getting something together which will have a bigger touchscreen than the iPhone or iPod touch. But it’s hard to tell how this device will fit, in the grand scheme of things.

It’s rather obvious that it won’t be a rebirth of the eMate the same way that the iPod touch wasn’t a rebirth of the MessagePad. But it would make some sense for Apple to target some educational/learning markets, again, with an easy-to-use device. And I’m not just saying this because the rumoured “Tablet Mac” makes me think about the XOXO. Besides, the iPod touch is already being marketed to educational markets through the yearly “Back to school” program which (surprise!) ends on the day before the September press conference.

I’ve been using an iPod touch (1st Generation) for more than a year, now, and I’ve been loving almost every minute of it. Most of the time, I don’t feel the need for a laptop, though I occasionally wish I could buy a cheap one, just for some longer writing sessions in cafés. In fact, a friend recently posted information about some Dell Latitude D600 laptops going for a very low price. That’d be enough for me at this point. Really, my iPod touch suffices for a lot of things.

Sadly, my iPod touch seems to have died, recently, after catching some moisture. If I can’t revive it and if the 2nd Generation iPod touch I bought through Kijiji never materializes, I might end up buying a 3rd Generation iPod touch on September 9, right before I start teaching again. If I can get my hands on a working iPod touch at a good price before that, I may save the money in preparation for an early 2010 release of a new touch device from Apple.

Not that I’m not looking at alternatives. But I’d rather use a device which shares enough with the iPod touch that I could migrate easily, synchronize with iTunes, and keep what I got from the App Store.

There’s a number of things I’d like to get from a new touch device. First among them is a better text entry/input method. Some of the others could be third-party apps and services. For instance, a full-featured sharing app. Or true podcast synchronization with media annotation support (à la Revver or Soundcloud). Or an elaborate, fully-integrated logbook with timestamps, Twitter support, and outlining. Or even a high-quality reference/bibliography manager (think RefWorks/Zotero/Endnote). But getting text into such a device without a hardware keyboard is the main challenge. I keep thinking about all sorts of methods, including MessagEase and Dasher as well as continuous speech recognition (dictation). Apple’s surely thinking about those issues. After all, they have some handwriting recognition systems that they aren’t really putting to any significant use.

Something else which would be quite useful is support for videoconferencing. Before the iPhone came out, I thought Apple may be coming out with iChat Mobile. Though a friend announced the iPhone to me by making reference to this, the position of the camera at the back of the device and the fact that the original iPhone’s camera only supported still pictures (with the official firmware) made this dream die out, for me. But a “Tablet Mac” with an iSight-like camera and some form of iChat would make a lot of sense, as a communication device. Especially since iChat already supports such things as screen-sharing and slides. Besides, if Apple does indeed move in the direction of some social networking features, a touch device with an expanded Address Book could take a whole new dimension through just a few small tweaks.

This last part I’m not so optimistic about. Apple may know that social networking is important, at this point in the game, but it seems to approach it with about the same heart as it approached online services with eWorld, .Mac, and MobileMe. Of course, they have the tools needed to make online services work in a “social networking” context. But it’s possible that their vision is clouded by their corporate culture and some remnants of the NIH problem.

Ah, well…

Back in Mac: Low End Edition

Part of the series.
(Series created on August 13, 2011, and applied retroactively…)

Today, I’m buying an old Mac mini G4 1.25GHz. Yes, a low end computer from 2005. It’ll be great to be back in Mac after spending most of my computer life on XP for three years.

This mini is slower than my XP desktop (emachines H3070). But that doesn’t really matter for what I want to do.

There’s something to be said about computers being “fast enough.” Gamers and engineers may not grok this concept, since they always want more. But there’s a point at which computers don’t really need to be faster, for some categories of uses.

Car analogies are often made, in computer discussions, and this case seems fairly obvious. Some cars are still designed to “push the envelope,” in terms of performance. Yet most cars, including some relatively inexpensive ones, are already fast enough to run on highways beyond the speed limits in North America. Even in Europe, most drivers don’t tend to push their cars to the limit. Something vaguely similar happens with computers, though there are major differences. For instance, the difference in cost between fast driving and normal driving is a factor with cars while it isn’t so much of a factor with computers. With computers, the need for cooling and battery power (on laptops) do matter but, even if they were completely solved, there’s a limit to the power needed for casual computer use.

This isn’t contradicting Moore’s Law directly. Chips do increase exponentially in speed-to-cost ratio. But the effects aren’t felt the same way through all uses of computers, especially if we think about casual use of desktop and laptop “personal computers.” Computer chips in other devices (from handheld devices to cars or DVD players) benefit from Moore’s Law, but these are not what we usually mean by “computer,” in daily use.
The common way to put it is something like “you don’t need a fast machine to do email and word processing.”

The main reason I needed a Mac is that I’ll be using iMovie to do simple video editing. Video editing does push the limits of a slow computer and I’ll notice those limits very readily. But it’ll still work, and that’s quite interesting to think about, in terms of the history of personal computing. A Mac mini G4 is a slug, in comparison with even the current Mac mini Core 2 Duo. But it’s fast enough for even some tasks which, in historical terms, have been processor-intensive.

None of this is meant to say that the “need for speed” among computer users is completely manufactured. As computers become more powerful, some applications of computing technologies which were nearly impossible at slower speeds become easy to do. In fact, there certainly are things which we don’t even imagine becoming which will be easy to do in the future, thanks to improvements in computer chip performance. Those who play processor-intensive games always want faster machines and they certainly feel the “need for speed.” But, it seems to me, the quest for raw speed isn’t the core of personal computing, anymore.

This all reminds me of the Material Culture course I was teaching in the Fall: the Social Construction of Technology, Actor-Network Theory, the Social Shaping of Technology, etc.

So, a low end computer makes sense.

While iMovie is the main reason I decided to get a Mac at this point, I’ve been longing for Macs for three years. There were times during which I was able to use somebody else’s Mac for extended periods of time but this Mac mini G4 will be the first Mac to which I’ll have full-time access since late 2005, when my iBook G3 died.

As before, I’m happy to be “back in Mac.” I could handle life on XP, but it never felt that comfortable and I haven’t been able to adapt my workflow to the way the Windows world works. I could (and probably should) have worked on Linux, but I’m not sure it would have made my life complete either.

Some things I’m happy to go back to:

Crazy App Idea: Happy Meter

I keep getting ideas for apps I’d like to see on Apple’s App Store for iPod touch and iPhone. This one may sound a bit weird but I think it could be fun. An app where you can record your mood and optionally broadcast it to friends. It could become rather sophisticated, actually. And I think it can have interesting consequences.

The idea mostly comes from Philippe Lemay, a psychologist friend of mine and fellow PDA fan. Haven’t talked to him in a while but I was just thinking about something he did, a number of years ago (in the mid-1990s). As part of an academic project, Philippe helped develop a PDA-based research program whereby subjects would record different things about their state of mind at intervals during the day. Apart from the neatness of the data gathering technique, this whole concept stayed with me. As a non-psychologist, I personally get the strong impression that recording your moods frequently during the day can actually be a very useful thing to do in terms of mental health.

And I really like the PDA angle. Since I think of the App Store as transforming Apple’s touch devices into full-fledged PDAs, the connection is rather strong between Philippe’s work at that time and the current state of App Store development.

Since that project of Philippe’s, a number of things have been going on which might help refine the “happy meter” concept.

One is that “lifecasting” became rather big, especially among certain groups of Netizens (typically younger people, but also many members of geek culture). Though the lifecasting concept applies mostly to video streams, there are connections with many other trends in online culture. The connection with vidcasting specifically (and podcasting generally) is rather obvious. But there are other connections. For instance, with mo-, photo-, or microblogging. Or even with all the “mood” apps on Facebook.

Speaking of Facebook as a platform, I think it meshes especially well with touch devices.

So, “happy meter” could be part of a broader app which does other things: updating Facebook status, posting tweets, broadcasting location, sending personal blogposts, listing scores in a Brain Age type game, etc.

Yet I think the “happy meter” could be useful on its own, as a way to track your own mood. “Turns out, my mood was improving pretty quickly on that day.” “Sounds like I didn’t let things affect me too much despite all sorts of things I was going through.”

As a mood-tracker, the “happy meter” should be extremely efficient. Because it’s easy, I’m thinking of sliders. One main slider for general mood and different sliders for different moods and emotions. It would also be possible to extend the “entry form” on occasion, when the user wants to record more data about their mental state.

Of course, everything would be save automatically and “sent to the cloud” on occasion. There could be a way to selectively broadcast some slider values. The app could conceivably send reminders to the user to update their mood at regular intervals. It could even serve as a “break reminder” feature. Though there are limitations on OSX iPhone in terms of interapplication communication, it’d be even neater if the app were able to record other things happening on the touch device at the same time, such as music which is playing or some apps which have been used.

Now, very obviously, there are lots of privacy issues involved. But what social networking services have taught us is that users can have pretty sophisticated notions of privacy management, if they’re given the chance. For instance, adept Facebook users may seem to indiscrimately post just about everything about themselves but are often very clear about what they want to “let out,” in context. So, clearly, every type of broadcasting should be controlled by the user. No opt-out here.

I know this all sounds crazy. And it all might be a very bad idea. But the thing about letting my mind wander is that it helps me remain happy.
