Social Media

So I joined Facebook yesterday. Giving in to subtle social pressure, I guess. But I don’t yet (or, if you prefer, still don’t) see what the big attraction is.

At least Facebook actually let me join. When I tried to join MySpace a couple of years ago they, well, technically they let me join, too, but something went wrong with the account set-up and I was never able to edit my account: Any changes I made were immediately lost. I couldn’t even delete the account and start over! And MySpace has (or had, at the time) nonexistent user support: I wrote them twice asking for help, and all they did was send me back entries from their FAQ that I’d already read. Useless.

What do I expect to get out of Facebook? Honestly, I have no idea. I mainly use the so-called “social media” for two purposes:

  1. To keep in touch with friends.
  2. To follow writers I find interesting or who are writing about subjects I enjoy.

For the most part, I get all of this through the blogs I follow (and I follow dozens of them), including LiveJournal, which has pretty much shown itself to be the best one-stop-shopping site for keeping up with friends and acquaintances.

I can count the number of times I’ve gone to sites like Digg on my fingers. I have a Twitter account which I use sporadically, but Twitter just doesn’t provide much depth or a decent signal-to-noise ratio. (Debbi sometimes teases me about Twittering when we’re out-and-about, but really I’m not very active there. Not compared to many people.)

So anyway, Facebook: I imagine I might encounter a few old acquaintances there, but honestly I’m already in touch with most of my old friends through e-mail and the Web. The mere existence of the Internet turned out to be the 90% solution for that. But maybe I’ll be surprised.

So Facebook might just end up being another account I created that ends up laying fallow. But hey, at least it’s free.

Q&A: How Did You Get Into Software?

(Ganked from Nadyne.)

I think I was first exposed to computers by a neighbor of mine when I was about 8 or 9 (so, 1977 or 78) who had somehow piqued my interest with some stories of his programming mainframes. He loaned me a book he had on programming in FORTRAN, which I thumbed through but didn’t really understand. I’m not sure it was a very good book, to be honest, although at that point I had no idea what distinguished a good book on programming from a bad book. (It’s not clear to me that most people who write programming books know this either.)

Also around this time I got into video games courtesy of the Atari 2600, which was the most popular (at least in my neck of the woods) game console of its day. There was even a “programming in BASIC” cartridge for the system which I bought with images of programming my own games, but it was a waste of time since its capabilities were, uh, extremely limited. But also around this time a friend of mine, Ben, got a TRS-80 Model I, which actually did have a full BASIC programming language. I borrowed his books on BASIC programming and wrote out – in long-hand on lined paper! – lengthy programs which represented little games. I’d go over to his house and type them in and see if they worked, debug them, etc. It was all totally ad-hoc, but those days I spent lots of time writing and drawing random stuff on paper, so it was right up my alley.

My parents bought me my very own TRS-80 Model III, which must have been when I was 11 or 12 given that it was released in 1980. So I was able to create all my own little games, and I’d also create little animation programs with the rather primitive graphics system. It had a tape drive and 4K of RAM, and I wrote a text adventure game which filled up the whole of memory, and I had to cut corners to get it to fit in. Later it got upgraded to 48K of RAM with a floppy drive. This was the day of computer magazines which printed whole programs in source code, and I subscribed to one: Softside. I especially enjoyed the text adventure games, in which they encoded all of the text strings using a simple algorithm so you wouldn’t have the game spoiled for you while you typed it in. On the other hand, you ended up with some interesting typos in the strings when you ran the program.

(I sometimes wonder if typing in all this stuff from paper helped make me such a fast typist, especially since I’m a two-fingered typist.)

In late 1981 my friend Rob – who at this point qualifies as my oldest friend with whom I’m still in contact – moved in across the street. They had an Apple II+, and we spent many hours on that thing playing Ultima II and watching MTV. This was a big step forward since it had better graphics and color, which my TRS-80 didn’t have. A couple of years later my Mom bought an Apple IIe, which pretty much put my TRS-80 into mothballs.

My next step in actual programming came through playing play by mail games, which inspired me to construct my own turn-based computer games, which my friends would play. I wrote an elaborate system in BASIC to track everyone’s moves and the state of the game, and emit board state to the screen from each player’s perspective (one of the things I thought was neat about these games was that you could only see a limited amount of the board, quite different from real-time board games). Unfortunately I had no idea how to write printer code, so I had to copy all the boards onto paper to hand them out. Did I mention that I had a lot of free time back in the day? (Did I mention that my grades weren’t so great early in high school?)

By senior year of high school I was seriously interested in computer programming, and I signed up for two programming courses at once, a full-time class in Pascal, and a part-time class in BASIC (the instructor insisted I take the latter class in order to take the former). These were my first exposure to structured programming principles. I also worked part-time in the computer lab and had to restructure a program they were using in the office. This was my first experience working with someone else’s code, and it was more than I could handle at the time – it was very slow going. I just shake my head when I reminisce about it, since these days I wade into thousands of lines of code I’ve never seen before on a semi-regular basis.

The other thing to mention here is that Rob’s mother bought one of the very first Macintosh computers, which must have been right in 1984. It had MacPaint and MacWrite, plus of course an ImageWriter. The screen size, graphics, and color were a bit of a letdown compared to the Apple II, but the interface and software made up for that. I still have a paper print-out of a drawing I did in MacPaint on that very machine. I don’t really remember Rob and I using that machine for much more than novelty fiddling around – the Apple II was still the game system – but in senior year – by which time Rob had gone off to college – my new friend Matt also had a Mac, and we spent many, many hours after school at his house playing Dungeon of Doom on it.

In 1987 I headed off to college at Tulane, and although I didn’t really know what I wanted to do with my life, I did want to keep up with programming. Tulane was a little draconian about its computer science courses: I wasn’t able to test out of classes with material I’d already taken, so I spent my freshman year being re-taught stuff I’d learned the year before. Sophomore year, though, we moved on to C more advanced information about how computers work. By the end of the year I’d decided to declare my major in CS, since the competing majors (English and art) were things I thought I could work on on my own without formal collegiate training. (Naturally, I’ve done fairly little creative writing or drawing ever since. Oh well!)

So that’s when I committed to a career in software When I finished college I felt somewhat deficient in my programming skills – in particular, use of pointers in C still baffled me from time to time – so I went off to graduate school at Wisconsin. Although I didn’t get a Ph.D. there, I did have the opportunity to work with an outstanding programmer on a research project and I learned a tremendous amount from studying his code and talking with him about how he designed software.

I was never a Macintosh programmer in the classic days. Whenever I tried to learn Mac programming I was either daunted by the high price of the developer tools (“Hmm, developer tools or four months of comic books…?”) or I would read about what was involved (the APIs and the lack of protected memory) and it just didn’t seem worth it, especially once I had experienced doing programming on UNIX systems. So my first experience with graphics programming was with X Windows. On the bright side, once Apple moved to a UNIX OS with the advent of Mac OS X, that made it an ideal system for my programming background.

When I look back on it, I often feel like I backed into being a programmer. I wasn’t a hacker or prolific programmer like many of my peers at the time, and sometimes I’d wonder if I wasn’t a fraud because programming didn’t consume my hobby time like it did so many other peoples’. But I’ve always tended to spread my time and attention across a variety of hobbies and interests – as even a casual reading of my journal should prove. Despite this I’ve ended up as a solid software engineer (well, I think so, anyway) in my career. Programming isn’t the be-all and end-all of my life, but I still enjoy building things and seeing them work, and all things considered I don’t regret the choices I made to end up where I am.

Not So Cuil

I decided to search for my name on the new search engine, Cuil (pronounced “cool”). The results were disappointing: The top hit was to my old web page, and the rest of the first page were either blogs I had commented on, or who had me in their blogroll. But this blog? Doesn’t show up.

Fail.

Twittering Away

A few weeks ago I gave in to peer pressure and joined Twitter. You can find me there under mrawdon. Okay, I wasn’t really being pressured, but I’d several of my cow-orkers were hanging out there making pithy remarks, so I decided to sign up.

I’ve joked that Twitter is “like blogging only without the pesky content”. I’ve also seen it called “microblogging”, which I take to mean, “There is content, but there isn’t very much of it.” Which seems about right: I see little tidbits of real content here and there, but most of Twitter consists of tiny, generic snippets of thought which are either devoid of depth, or devoid of meaning due to a lack of context.

It’s the lack of context that really makes Twitter a suboptimal experience compared to blogging: If I didn’t know the people I’m following personally, there’d be essentially nothing there for me. So it’s no surprise that the few times I’ve tried to go out and find new Twitterers to follow, I’ve come up empty because it’s all just random nattering without any context to give it meaning, or any depth to give it value in the absence of that context. (By contrast, I’ve found many fine journals and blogs over the years simply by poking around in one place or another on the Web, even if I didn’t know the author beforehand.)

If I were to use a single word to sum up Twitter, I think it would be “disposable”. It’s hard enough to build anything of lasting value in a blog format, and it looks to be nearly impossible on Twitter. I don’t expect to become educated or informed through Twitter, and I strongly doubt there’s anything of interest in “the archives”. Will I ever go back to look at my old tweets to recall what was, like I do with my journal? Probably not. I wonder whether anyone else does so with their tweets?

Clearly a lot of people are having fun on Twitter, though. A tool like Twitteriffic turns Twitter into something like a push-notification system, which means less effort on your part to keep up with what your friends are doing. (This isn’t very different from following a blog via an RSS feed, though.) But it seems like most of the fun is in following the snarky remarks and exchanges and the occasional raw outbursts that pepper the site.

So there’s some value in that; people have fun and get a few laughs. But there’s a lot of fun and plenty of laughs elsewhere in the world, and a lot of it is more rewarding when it’s not restricted to 140 characters.

WWDC 2008

I put in my time at WWDC this week. In addition to staffing the Xcode lab, I also was demo boy for a presentation – the first time I’ve been on stage at a conference other than Q&A sessions.

It all went pretty well, with one exception: Mid-afternoon yesterday, shortly before the presentation, I started getting a headache. In the somewhat overheated presentation room, the headache got worse. I was okay when I was actually driving the demo, but waiting between demos I was feeling really cruddy. Afterwards I went to the lab for my shift, but at that point the headache had gotten really awful and my stomach felt upset. I finally left early and caught the train back home, where Debbi picked me up at the station. At home I went straight to bed and slept for 12 hours nearly-straight.

I’m not sure if I was dehydrated (we’re having another heat wave here), or had a touch or food poisoning, or just had a migraine. But I felt much better this morning, if a little wobbly. Possibly from skipping dinner.

There are a lot of people for whom WWDC is a big social event, and they spend the whole week up there, even renting a hotel room in the city. I’m not one of those people, so I’m back in the office today. In a way I envy those folks, since I’m sure it’s a lot of fun for them, seeing old friends etc. I rarely have that experience, even at SF conventions, and I know a lot more people in fandom than I do in the Mac developer community. Ah well. Diff’rent strokes and all that.

The Scanner Blues

A few months ago I took the plunge and upgraded our desktop computer at home to Leopard. After all, I’d been running it both at work and on both of our laptops, and it seemed fine. Okay, I’d had to update some freeware and shareware, but that’s to be expected. I should probably update them more than once every 3 years anyway. :)

Well, it went smoothly, except for one problem: I can’t get my scanner to work under Leopard. Which is a bummer, since I use the scanner to scan book and comic covers for this journal, album art for my iTunes library, and also to scan items I put up for sale on eBay.

I have a Canon CanoScan LiDE 80, which was reasonably inexpensive and (more importantly) small and flat, but with a decent-sized platen for scanning. It’s worked well for several years, on both Panther and Tiger. But on Leopard it doesn’t work at all.

My first problem is that I use the version of Adobe Photoshop Elements that came with the scanner, which means that it’s now quite old, and won’t even launch on Leopard. If this were the worst problem, it would be surmountable; I could try to figure out Image Capture, which comes with Mac OS X, or I could try to use GraphicConverter or buy a copy of VueScan. Or heck, I could just buy the newest version of Photoshop Elements.

The larger problem is that the LiDE 80 doesn’t seem to be supported on Leopard, and in fact Canon seems to do a poor job of updating their drivers – the most recent drivers for this scanner were posted on 10/4/2007, which was shortly before Leopard was released. So I infer that they haven’t really been updated to work with Leopard. And n matter what I try, I haven’t been able to get them to work, even using the TWAIN driver, as other applications don’t seem to recognize Canon’s TWAIN driver. (The drivers also appear to be available only for PowerPC machines, which is fine for my desktop machine, since it is such a machine, but I’d like to buy an Intel-based Mac sometime soon, and that will pretty much hose it.) Someone recommended I check out SANE to see if they have a driver for it, but they don’t; apparently the scanner uses a “backend” which SANE doesn’t yet support. Alas.

It appears that other people have had the same problem, but I haven’t found a concrete solution. This thread has a lot of discussion about the issue, and some people seem to have gotten it to work, but others have not. I’m one of the “have not” people. On the other hand, one person was able to get it to work with VueScan, which I haven’t tried. (Although since VueScan seems to have a free trial, perhaps I should.)

So anyway, my solution to all this was to realize yesterday: Hey, I bought a second internal hard drive for the desktop machine a while back! So I partitioned that drive and installed Tiger on one partition, brought it up to date, and then installed the Canon software along with Photoshop Elements. Sure enough, the scanner works great in that environment. So at least that gives me a solution for the short term.

The longer term will involve buying a new computer, and then probably a new scanner. It seems that Epson has been releasing new drivers for Leopard, so I might give them a try, perhaps the V200 Photo. I’m certainly more inclined to buy a scanner from someone who appears to be actively supporting the platform.

If anyone has any advice or suggestions on what to get, I’d appreciate it.

Of course, I’ve needed to buy a new stereo receiver for months, and haven’t gotten around to that, so who knows when I’ll get to doing all this? (Then again, I installed Tiger on a new partition on a whim last night, so it could happen at any time…)

iPhone Experience

Impressions after a few days with my iPhone:

First of all, realize that I think the most practical piece of computer hardware to come along in the last ten years are Palm PDAs, and the only thing they have over the Apple Newton is that they’re faster, and they fit easily into my pocket. I use them to store my calendar, my address list, and (most importantly) my extensive want list of comics, books, CDs, and other items I collect. And I can back up the data onto my computer (which is critical in all three cases).

By contrast, I have fairly little use for a mobile phone: I’ve had a low-end phone for a while, but I mainly use it to coordinate with Debbi, and in case of emergencies. I don’t use it for work, and I sometimes forget to take it with me, and rarely miss it. So it’s handy, but far from essential. I use my land line far more than I use my cell phone.

So I suspect I’m an unusual customer for an iPhone. On the other hand, since I was gifted with one I was certainly interested enough to activate it (and even paid an early-cancellation fee on my existing phone to do so!).

The hardware is nice: The form factor is fine for a handheld computer, a little taller and narrower than my PDA, and a lot thinner. As a phone it feels funky, a solid rectangular object, but I’m used to a clamshell enclosure that curves around my cheek and where the mike is closer to my mouth. I’ll probably get used to that difference.

The glass screen is surprisingly durable, I’d expected I’d scratch it within the first few days of use, but it’s still pristine. I tend to carry my stuff in my pockets rather than in a belt holster, so I bought a MarWare Sidewinder for it. It comes with a belt clip and a wrap for the earphones, as well as a clear film for the screen, which seems to work well. (Note to self and others: When applying plastic film to iPhone, do so in a cat-hair-free zone.)

Voice quality seems fine, although I think my old Verizon service was somewhat clearer. My impression is that voice quality will vary widely depending on where you are and, well, your personal preference. People seem very opinionated when it comes to wireless services.

Making calls is really slick and easy: Just find someone in your address book and hit their number. Or dial a number. And it brings up a palette of several options while a call is in progress, so you don’t have to remember what button to hit to put a call on speakerphone.

The user interface is responsive enough that I almost never feel like I’m waiting for the phone to do anything, although sometimes I do wait for it to get data from the network.

The “mechanical” aspects of the UI work well for me: My fingers aren’t small (though they’re not huge), and I find the general buttons and the pop-up keyboard to both be pretty easy to use. I’m getting better with the keyboard: Mainly I had to train myself to hold the phone level, rather than at a slight tilt to the side, and that made keypunching much more accurate. That’s a much easier hill to climb than, say, learning Graffiti. I rarely have to hit anything twice because I “missed” the first time, but I do sometimes. Not enough to annoy me. On the other hand, I have a hard time seeing myself doing extensive typing (e.g., journal entries of any length) from the phone.

Scrolling is simple, and the zoom gesture is really cool.

Network connectivity: WiFi connectivity is easy to set up (although if you have a 14-character password for your home network, like I do, then typing it in while you’re still getting used to the keyboard is a bit tricky; it took me three tries), and the phone is good at locating a network when it’s in a new location. EDGE connections feel (to me) to be about half as fast as WiFi, which is fast enough to look up maps, but a bit slow for surfing the web.

Google Maps is the killer app on the iPhone. It’s got the street maps, satellite view, traffic info (depending on your location), easy scrolling and zooming, directions, and bookmarks. It’s the first feature of the phone I used which made me glad to have the phone: When we went minigolfing on Saturday and found our destination was closed, I looked up the location of a nearby minigolf course which I’d seen, and found directions for it. It’s easy to envision finding other destinations in the same way (one of the iPhone ads already does so).

The Safari web browser is pretty handy, although I suspect it has some subtleties I have yet to figure out. I had some early problems with it crashing on me several times, but it’s stopped. I did reboot the phone when it happened, so maybe that cleared up whatever the glitch was.

Mail is a nice convenience, although it’s not something I really need. Since it doesn’t have mailbox filters, you’ll need server-side filters in order to make good use of it. Unfortunately, my Dreamhost e-mail (i.e., the address for this site) requires a security certificate to access, and I can’t find a way to set up such a thing on the iPhone. That’s a bummer.

The biggest weakness of the iPhone, for me, is that you can’t synchronize the Notes to your computer. As I said above, I keep extensive notes on my PDA, mainly for my collecting hobbies (but for other things too), so this is the biggest obstacle to my simply replacing my PDA with the iPhone. Because I simply can’t afford to lose this data. I could perhaps create a Web page with the info and access that with the phone, but then I couldn’t really add to it while I’m out shopping. Hopefully this will be one of the first issues to be addressed.

(To be fair, I haven’t dived very deep to see if there are ways to work around these issues. Maybe there are. I’m not real interested in “hacking” my phone, however.)

Syncing addresses and music is exactly as trivial as you’d expect it would be. Mail accounts, calendars and Safari bookmarks all gets synced, too.

I haven’t used the camera, photo albums, voice mail or text messaging much yet. I haven’t used the calendar at all (until I can replace my PDA with the phone I may keep using it for my calendar). I also haven’t really used it as an iPod yet, although Cover Flow is a pretty nifty way to scan through all your music on the thing.

Overall I’m pretty happy with the phone: It’s useful as a phone, it’s very useful as a map program, and its has a lot of other features come in handy from time-to-time. While I really wish it could sync Notes, it’s still very polished for a first-generation piece of hardware.

Oh, and the first software update for the phone is available.
