A non-review of Avatar

Thursday, December 31st, 2009

It’s not very often that I see a movie that moves me enough to write something about it. Sure, a couple years back, I put together a list of some of my favorite comedies, but those were capsule summaries written about movies that were, in general, quite a few years old.

Yesterday, however, I saw Avatar, and was, for the first time since the 1977 release of Star Wars (I refuse to call it ‘Episode IV’), absolutely amazed by a film. As such, I felt moved to write a little bit about Avatar.

This is not a review, and it (hopefully) doesn’t contain any spoilers. Instead, I’ve focused on my reactions to Avatar, some comparisons to that original Star Wars movie, and what I think it means for movie making going forward.

First off, after sleeping on it, I definitely stand by the three-word (five, counting the parenthetical) review that I tweeted yesterday:

Go see it (in 3D)

Go see it because it’s entertaining. Go see it because it represents the state-of-the-art in movie visual effects. Go see it if you’re a fan of cinema in general, and want to see where filmmaking may be headed in the future. But really, just go see it–Avatar is well worth the cost of admission, regardless of the reasons.

Does that mean it’s a perfect movie? No, in fact far from it–the story, in particular, is too predictable and has been seen many times before. Then again, Star Wars wasn’t necessarily a completely original story, either. Another recent favorite of mine, Star Trek, was itself very similar to Star Wars (this funny video demonstrates just how similar). In short, I don’t necessarily mind a predictable story if it’s presented well and the rest of the movie works with the story.

One way to password protect a WordPress site

Tuesday, October 13th, 2009

I was helping a friend set up a site for their family, and they wanted it to be password protected. I protect our family site using Apache’s basic access protection (httpauth), and it works well enough, so that’s how I set up his site as well.

However, we then had nothing but trouble with the Flash-based image uploader in WordPress, which is a tool I don’t personally use. After some digging, I discovered that the Flash-based image uploader simply won’t work with httpauth.

Because the objective was to keep out unwanted visitors, I found a workaround — it’s not perfect security, but it seems to do the job well, and allows the Flash-based image uploader to work. I disabled the httpauth access restriction, then installed two plug-ins:

  • Restricted Site Access: This plug-in prevents anyone from seeing the site without first logging in. We then created one generic username/password for my friend to give out to all his relatives (which is what we would have done using httpauth, too).
  • Peter’s Login Redirect: This sends users to the home page of the site after login, instead of to their control panel. I’m not sure why, but after logging in, our generic user was going to their control panel. This plug-in solved that problem.

The end result is a site that’s protected from casual visitors, as well as robots (though we’ve also got a robots.txt file set up, just in case). It’d be nicer if WordPress would just fix the httpauth issues, but it seems they’re not interested in doing that.

In search of iPhone golf GPS and/or scoring apps

Friday, June 26th, 2009

I’m in the midst of a huge round-up of iPhone golf-specific GPS (range finder) and/or scorecard apps for Macworld. As of now, I’ve identified 32 of them, but I’m wondering if I’ve missed any. If you have a second, please check out this list and let me know (via a comment here or via Twitter) if you’re aware of any other apps.

Read on for the list (note that some of these may be mis-categorized as I haven’t tested all of them yet)…

Tiger Woods for iPhone has a difficult(y) problem

Monday, May 18th, 2009

I’m a big fan of golf, both real and virtual. The best iPhone golf game I’ve yet found is Tiger Woods PGA Tour, from EA. At $10, it’s not cheap, but it is fun. It does, however, suffer from one fairly annoying problem: it’s way too easy in its default mode. As an example, here are the final results from a four-round tournament at St. Andrews:

Per round, my average score (my player’s first name is Wheat) was 15.25 under par, which is simply unbelievable. Look at second place–14 under par for four rounds, or worse than I do for one round! At about 3.5 strokes under par per round, however, the second place score is much more realistic.

So what’s the problem? The problem is that TW for the iPhone includes both a caddy and a putt preview feature. Combined, those two features making putting the ball ridiculously easy. Here’s how to use those two features together to crush the PGA events in Tiger Woods.

Need help with a project

Friday, May 15th, 2009

Greetings, my faithful handful of readers…

For an upcoming Macworld project, I need a large volume of email. To that end, I’ve set up a new account in which to build my collection. The address is:

ineedalearjet@gmail.com

Please feel free to share this address with anyone, post it on your blog, Tweet your friends about it, etc. I’m looking for a big collection; I assume most of it will be spam, but if you feel like just dropping a line and saying “hello!,” that’s fine, too! Note that I won’t be replying to any messages sent to this account.

Thanks in advance for help spreading the word!

GPS, daylight savings time, and cars

Sunday, March 8th, 2009

With this morning’s semi-annual changing of the clock for Daylight Savings Time (DST), I’m once again left to ponder…why, in this era of GPS-equipped automobiles, do I have to manually set the clock in my car? We had, until very recently (we sold one), three cars with factory GPS units. Of those three, only one uses the GPS signal to set the car’s clock. In the other two vehicles, we have to manually adjust the clock, even though an extremely accurate time and date signal is one of the features of the GPS satellites.

So my car knows the date, and it knows the correct time…so why can’t it figure out that DST has started or ended?

Things have definitely improved over the last 30 years, though–today, we had only a handful of clocks to change. In addition to one of the cars, there were a couple of televisions (another device that seems to me should be capable of changing its own clock), our microwave, and a few assorted clock radios and wall clocks. But most of the clocks we own synchronize automatically with a time signal, so they were correct when I woke up this morning. The computers, of course, handle the change seamlessly. (The fact that I stopped wearing a wrist watch a few years ago also helps; I have ten or so sitting in a drawer somewhere, but I no longer bother to set them.)

I’m not sure I’ll live long enough to see a DST start/stop day where I don’t need to manually set a clock…but I’m hoping I do!

Indoor flying fun

Thursday, January 1st, 2009

For quite a while, I’ve wanted an electric radio controlled (R/C) helicopter–one of the small ones you can fly around inside the house. Over the last couple years, I’ve tried cheap versions (complete waste of money; they fly like crud), and the expensive versions seemed too, well, expensive for what would be nothing more than a silly time waster.

Then, just before Christmas, E-Flite released the new Blade mCX, a smaller, lighter, and easier-to-fly version of their Blade CX2. The CX2 was one of the expensive models I’d passed on earlier. The mCX, however, comes in $50 cheaper than the CX2, and came close enough to my self-imposed $100 limit that I bought myself one for Christmas :). (Click the image at left [and any image in this writeup] for a larger view.)

After only a few minutes with the mCX, I was hooked. This machine is unlike any other R/C helicopter I’ve ever tried to fly. Within a couple minutes of my first power-up, I had it hovering in place, and could maneuver it relatively well. Even for me, a complete novice to R/C flying, this machine is incredibly easy to fly. R/C purists probably dislike it, though–relying on dual counter-rotating rotor blades and a gyro, the mCX isn’t a “real” R/C helicopter in any sense. But for my desires, it’s (nearly) perfect.

The mCX weighs one ounce (with battery), and has a rotor span of just 7.5 inches. Everything about this machine is tiny, including the motors (the round items in the image at left) and the battery (visible at the bottom of the image; it’s got a red dot on it). The front of the machine is the brains, though–a circuit board there holds the gyro, motor control units, fully proportional servos, and radio receiver. Amazing that it all weighs but an ounce.

Combine that with very sensitive flight controls, and you can fly the mCX almost anywhere–I’ve flown it above the garage’s workbench, for instance. The throttle is amazingly precise, making it easy to fly at whatever altitude you desire. As a brief example, here’s a video of me flying around in the den, trying to keep the mCX within view of the fixed video camera:

Deals to be found at the Apple refurb store…

Monday, October 20th, 2008

If you know me at all, you know how I feel about glossy screens, especially on laptops. As nice as the new MacBook and MacBook Pros are (and they are very nice, based on some early hands-on time with the new MacBook at the local store), the glossy screens are a deal breaker for me. I tried to use a MacBook for six months or so, but in the end, the glossy screen was too much for me, so I went up to the MacBook Pro and its nice matte display.

With the lack of a matte option on the new MacBook Pro line, I won’t be buying another Mac laptop (of the 15″ variety) until Apple comes out with some form of non-glossy screen–whether that’s a true matte screen, or just an effective anti-glare coating, I don’t really care. But until there’s a solution, I’m going to use what I have for as long as I possibly can.

My current machine is a two-year-old 15″ 2.33GHz MacBook Pro with 2GB of RAM–and it’s a very nice machine. However, it’s already two years old, and I want to get at least five more years out of my matte screened laptop…so I figured I’d go look on eBay for used last-gen 2.6GHz MacBook Pros–the fastest 15″ machine with a matte screen available, basically.

On my way to eBay, though, I got sidetracked by the Special Deals section of the Apple Store–otherwise known as the Refurb Store.

Music in the new iPod nano ad…

Tuesday, September 9th, 2008

Because I couldn’t find this anywhere else on the net, here it is … the music in the new iPod nano ad is a song called Bruises by Chairlift from an album called Does You Inspire You. I found this by doing a lyric search on the first line (“I tried to do handstands for you…”), which led me to this blog post — not directly about the iPod nano ad, but it does mention the song and the lyrics.

iTunes store link

The new nano may just get me to upgrade my original “tall” nano, which is one of my favorite iPods … but the new one has some really nice sounding features; I’m going to try to go see one in person tomorrow.

New Macworld video posted…

Friday, June 6th, 2008

It was my turn on the Macworld video blog-go-round again this week. The topic I chose is “working with multiple Macs in one home.” The end result is a 10-minute clip covering a number of third-party tools that make the process easier, and a couple of general usage hints.

Due to the huge number of downloads, the size of the macworld.com video is 320×240. But if you want, you can see grab the original 640×480 version right here. Warning, it’s 185MB in size (I didn’t work very hard to compress it, so the quality is good, but it’s huge).
