Dishonesty

I finished the novel Empire, by Orson Scott Card, a couple months ago and had been meaning to write a review of it, or at least a commentary on it, since then. At this point, enough time has passed by that I'll not be including very much in the way of specific details from the book, though there will be some spoilers.

I think the title above succinctly sums up the book in a variety of ways. Let's start with what would typically be a minor point, since I doubt Card approved it. On the other hand, I generally look to the blurbs to give me some idea of a book's content, and thus a false and misleading blurb is something that will lead me to be less likely to buy other books from the same publisher. In a perverse way, the blurb is representative of the book -- not in terms of factual information, but in terms of being thinly masked propaganda.

So, what does the blurb say? Here it is:

The American Empire is growing too fast, and the fault lines at home are stressed to the breaking point. The war of words between Right and Left has collapsed into a shooting war, though most people just want to be left alone.

The battle rages between the high-technology weapons on one side and militia foot soldiers on the other, devastating the cities and overrunning the countryside. But the vast majority, who only wan tht killing to stop and the nation to return to more peaceful days, have technology, weapons, and strategic geniuses of their own.

When the American dream shatters into violence, who can hold the people and the government together? And which side will you be on?

So, I (naturally, I think) expected a cautionary tale set in the near future, with an imperial America, a civil war between extremists, and presumably a protagonist representing a large middle. Instead, what the reader gets is a political polemic in which all liberals (which, true to ultra-right-wing usage, is equated with extremism) are evil. Even the right wing "side" of the war ends up being (spoilers start here) a head fake by liberals. There's a token "good Democrat"; you know she's good because she sides with the Republicans.

What are we left with? A grand conspiracy to take over the government financed by a thinly-disguised George Soros character. A Bond-like secret headquarters underneath an island in a lake. The liberal conspirators have all sorts of neat, futuristic weapons, but their soldiers are all effete and unskilled (and sneaky backstabbers), eventually bested by virile, right-thinking true Americans (in fact, for some reason I either remember or misremember the liberal soldiers as being foreigners). Card making fun of Armand Hammer's name. A smattering of decent dialog and action. Some mild criticism of Fox News.

And then, to top off my disappointment, there's an angry diatribe written by the author at the end. Apparently, he's pissed off at criticism of his views. He rails against people seeking to rob him of his livelihood, though it's unclear to me that his income has in any major way been affected: he only makes the case for being excluded from SF conventions and the like. He doesn't mention his support for intelligent design as science, which I mention not as a religious comment but as a rather embarrassing lack, in a hard science fiction writer, of basic understanding of what science is.

What is apparent in his essay is that Card is one of those people who for some reason feel that their lives are affected, somewhat like action-at-a-distance, but the unrelated actions of others. Actually, not just their actions, but even their ability to act. In particular, he somehow thinks that the ability for people to marry others of the same sex affects the quality of his own marriage. His protestations aside, I fail to see the difference between this and opposition to interracial marriages. Some people just can't seem to let others live their own lives in peace, if they disagree with them.

And so, Card's closing essay at once clarifies the polemical nature of this "novel" and identifies him as an extremist, like the antagonists in his writing, who seeks control over other Americans' private lives.

New use for old socks

truphone: Killer iPhone app for international travel

Two days after the iPhone 2.0 software and the iTunes app store were released, I went on a family trip to Europe. So of course, in the days prior to my trip, I frantically installed, then reinstalled, the 2.0 software. This would make my phone much more useful during my trip, I reasoned. Well, it turns out I was right, and the main reason for that was the truphone application.

Truphone is a VOIP application, with one version running on Nokia phones and one iPhone version. The iPhone version appears as a separate application on the iPhone, providing buttons at the bottom of the display that provide access to your contacts, a keypad, a truphone web page for buying account credit, a list of recent calls, and a list of favorites (which, unfortunately, are specific to truphone and not copied from the Phone app). The application is exceedingly simple in operation:

  1. Sign up for an account and buy credit (when I signed up, they gave $8 credit for free; now they give $1 credit).
  2. Be someplace that has wifi that you can access.
  3. Make a call to one of your contacts, or dial on the keypad. These are calls to regular phones (landlines or mobiles), not to other other iPhones running truphone -- it's like SkypeOut.
  4. Pay $0.06/minute (now they've got packages that provide $0.015/minute to the US and Canada).

Perhaps paradoxically, this simplicity has caused some confusion among the commenters on the iTunes store. Part of this is truphone's fault, as they don't distinguish well in their online documentation between the Nokia and iPhone features. The Nokia app includes free truphone-to-truphone calling, SMS, etc. -- much more like a full Skype implementation. It also appears to integrate into the Nokia calling software, so that the phone automatically switches from regular cell to VOIP, depending on circumstances. The iPhone application is simpler, only including calls to regular phones and requiring you to consciously select wifi calling (by running the truphone app, rather than the Phone app).

I actually prefer the iPhone implementation. At this point, truphone doesn't have much market penetration, and besides I don't know that many people I might call who have iPhones or Nokia N95s. So being able to call other truphone users wouldn't have been useful during my trip (with one small exception: you know who you are). More importantly, I wanted to be 100% certain that I was making a VOIP call, and not a $2 or more per minute cell call. I didn't want my phone switching to regular cell calling because of a software glitch or because of some problem connecting to a hotel's wifi network. The fact that I was running the truphone application, not the Phone application, and that truphone only works with wifi, was very reassuring.

I spent at least a couple hours calling various phones here in the Seattle area, Philadelphia, south Florida, and China, from hotels in Prague, Venice, and Rome. Generally, call quality was quite good, equal to the best we've experienced using Skype, with the only issues being a weak signal in one hotel that required me to sit in a particular chair in the lobby that happened to be in a good spot. Also, I tried at one point to add credit to my account using my MacBook, but the truphone web site was abysmally slow; I connected to the mobile version of their add credit page and the transaction went off without a hitch. And it was great to be able to call relatives to let them know we arrived safely and keep them updated on our wanderings without having to deal with phone cards or similar unfamiliar contact methods.

So, is truphone useful for calls within the US? Probably not, unless you've somehow gotten yourself a plan with very few minutes and very high costs for additional minute usage. But, if you need to travel internationally, then calls using truphone are approximately 1/30 the cost of AT&T calls. You could easily pay for the purchase cost of an iPhone 3G with the savings from one international trip.

Getting the right iPhone 2.0 software

For those of you (like me) who followed the information I reference in a previous blog post, note that that unofficial iPhone 2.0 software was for the new iPhone hardware. If you (like me) have the original iPhone hardware, you need to follow the directions at MacRumors linked from the title to get the correct software for your hardware.

Initial iPhone 2.0 app impressions

Here are some of my initial observations about the iPhone 2.0 software:

Settings: Has a "Fetch New Data" item that lets you turn push updates on or off, set data fetch interval (includes the email check intervals for non-push email). Has a new "Mail, Contacts, Calendars" item, which consolidates various items (I think, I don't remember the details of this from the old OS) and includes under calendar "New Invitation Alerts", "Time Zone Support", and "Default Calendar" settings. The latter corresponds to the Calendar app UI now showing the multiple calendars synced from iCal. Played with simplified Chinese international keyboard a bit; neat to be able to draw characters by hand.

Contacts: The iPhone 2.0 software adds a "Contacts" app, which appears to just be a shortcut to the "Contacts" tab in the "Phone" app. We now have search, but it appears to be strangely limited, in that it doesn't search all fields. From playing with it a bit, it appears to search names and company, but not address or notes, for example. At least, this is my tentative conclusion. The on-screen keyboard has a "Search" button, but results update as you type; the "Search" button doesn't seem to do anything.

Calendar: Updated UI includes multiple-calendar awareness.

Maps: UI spiffed up. Circular cross-hairs vibrate as it progressively refines your location.

App Store: It works; looks just like the "iTunes" app.

And some third party apps: BA Flights: Mostly, thought perhaps not entirely, lame. Only lets you search for departures/arrivals within the current month. About what you'd expect: a three-button web app front end.

Talking Italian Phrasebook: Not sure that all of the phrases are correct, but pretty good for free.

Currency: Nothing fancy, just like the Stock app. A nice, simple app.

Exposure: Interface like iPod app. No Flickr upload capability. Not sure I'd pay $3 for Mobile Flickr. Need to compare this to MoPhoTo (which also doesn't seem to support upload).

NearPics: Very slow, and I'm testing via wifi.

Twitterific: Seems fine. Allows "attaching" photos to twitter updates, but I'm not sure this is something I'd like to do often; I think I'd be more likely to photoblog here on Blogger.

So, what do I want?

  • Skype! There is an app/service called TruPhone that seems Skype-like. Seems to include the equivalent of SkypeIn for no extra charge. It's in beta, but maybe I'll try it (if it won't insist on calling pay via wifi within the US, given that I have thousands of rollover minutes). I'll report after/during my upcoming trip on my experiences.
  • A good photoblogging interface that doesn't force me to switch to another blog platform. In other words, Blogger app.

Neat looking apps that I don't have an immediate need for:

  • SignalScope, a spectrum analyzer.
  • StageHand, a presentation remote that also displays your talk notes, allows you to highlight/point parts of your slides, etc.
  • OmniTuner, which seems, despite the emphasis on guitar, to be a chromatic tuner app. Orfeo is definitely a chromatic tuner, though with less impressive graphics and at twice the price.

And, finally, exactly how many payware tip calculators does the iPhone need? Do people really have trouble calculating tips using a regular calculator (such as the one built into to OS distribution)? Or just ballparking tips in their heads (how difficult it it to figure 10%, then either add in half of that again or double that)?

iPhone 2.0 report

Since I'm in the process of writing my part of a grant proposal before heading off on a trip, I figured, "Hey, why don't I update my iPhone to the 2.0 software?" The software is unofficially available; see this iLounge article for a good summary of how to get it. Here's how things went:

11:55AM: Option-clicked "Check for Update", selected .ipsw file, iTunes extracted update.
11:56AM: iTunes started "Preparing iPhone for software update..."
12:02PM: iTunes started "Updating iPhone software..."
12:04PM: iTunes started "Verifying updated software..."
12:06PM: iTunes started "Updating iPhone firmware..."
12:09PM: iPhone restarting, iTunes sees it, offers to set it up anew or restore from backup. I restored from backup.
12:11PM: iPhone restarting
12:12PM: iPhone reappears in iTunes list. Arrangement of icons same as it was before update. Only immediately apparent differences are "Contacts" and "App Store" icons. Set up synchronization in iTunes to sync all applications. Synced iPhone. 12:30PM: All done, now to see if it works...

More about iPhone apps

Some more-or-less random observations about the available iPhone apps (based purely on their app store descriptions and icons):

  • There's a lot of $0.99 apps; I'm not really sure what the rationale is (on the part of the software developer) for not just releasing such apps for free.
  • There are many free apps that appear to do the same thing as pay apps. Why would anyone pay for an app that simply produces a white screen to improve the iPhone's ability to act like a weak flashlight?
  • Here's my initial list of (free) apps: "BA Flights", "Currency", "Exposure", "Jott for iPhone", "NearPics", "Remote", "Talking Italian Phrasebook". Yes, we're going on a trip.
  • Disappointments: no Skype, no official Flickr app (the free version of Exposure is adware).
  • A fair number of cute ideas in some of these apps, but I don't think many really take advantage of the synergies available in the full range of iPhone capabilities.

iTunes App Store up and running

Wooo! The iTunes App Store is up! Just use Software Update to download iTunes 7.7, enable "show apps" in iTunes preferences, click on the "Applications" icon, and select "Get More Applications..." (similar interface to podcasts). Can't load the apps yet on the iPhone, since the iPhone 2.0 software hasn't been released, but you can at least browse and make a list (which I will be doing shortly).

Update: You can "purchase" applications and they'll download. This doesn't appear to use the shopping cart, but I've only tried free apps.

The future of video cameras

So, we're getting ready for a trip and really don't feel like lugging our Sony mini-DV camcorder along with our digital camera. Everyone's talking about the Flip Mino, so that would be a possibility. Then again, our still camera has a movie mode, with the same resolution as the Mino (640x480), except that it has a 12X optical zoom, better optics, and a better sensor. It doesn't have much in the way of video compression capability, storing its video as MJPEG (just a sequence of JPEG compressed frames), which means that videos require 1GB per 10 minutes or so. But that's not such a big deal these days. Even though it is discontinued and Konica Minolta is no longer in the camera business, there was a firmware update that allows it to use 2GB SD cards. A quick trip to Costco, and we have enough storage for our trip.

So, it seems that we're on the threshold of major change, not just in laptop computer mass storage, but also in video cameras. For those who need more than a cell phone or Mino -- and who aren't professionals -- what's the motivation behind getting anything other than a good digital camera with video capability? Pretty much every digital camera out there supports at least 640x480, or standard definition. They certainly have the sensors to capture HD. Flash memory prices will be low enough within the next couple years that it will really not make any sense to buy a hard drive camcorder. The only remaining question will be: do you really need to shoot 10 hours of video before the next time you'll be able to dump the video to a computer or DVD burner?

Speaking Respectfully

The title above links to one of the best illustrations I've seen of how to disagree with someone respectfully, even if that respect isn't reciprocated. This is something I should work on.

World RPS Society

Is this for real? Is there really a "World Rock-Paper-Scissors Society"? Is it just an elaborate joke? Would someone really put that much time into such a joke?

Water-fueled car?

Seems there's a company in Japan that says they've built a car that runs on water. Supposedly, they have a "membrane electrode assembly" that breaks water into hydrogen and oxygen; they then use the hydrogen to generate electricity, producing water as the result. Sounds too good to be true? Then it almost certainly is (actually, I would state it more strongly than that). By comparison, cold fusion is very believable. What's really impressive to me about this is the speed of creation of a quality Wikipedia page on the matter. The company had a press release on June 12, 2008, and the Wikipedia page was up on June 14.

Why won't US car manufacturers learn?

Today, we filled up our car's gas tank; it cost $4/gallon for the first time. At Costco. No doubt, in the months and years to come, people may read those last two sentences and wonder briefly if I was bragging about how low the price was.

So, Dodge has release the new Challenger, with an SRT-8 model for 2008 and two down-line models planned for 2009. The car gets 13 miles per gallon (city)! With a 19 gallon gas tank, that means you'll be spending more than $75 every 250 miles to drive this thing. If you drive 12,000 miles per year, that's about $3,700 on gas.

Are US car executive idiots? Yes, I'm not surprised that the 2008 limited edition run of 6,400 cars sold out. But do they really expect this car to sell well over any reasonable model lifespan and production run, given likely future gas prices? And who wants to drive around in a car that looks 30 years old when brand new?

Mac OS X 10.5.3 Update

Apple has released the Mac OS X 10.5.3 update, as of yesterday. This looks like it will be a big win for us Mac users, with stability improvements seemingly throughout the OS and included applications. Notable from my point of view are:

  • "Fixes reliability issues with iCal syncing." I use Spanning Sync (click this link to save $5) to sync iCal with Google and back, so I can keep my home and work Mac calendars in sync. This is a topic of conversation on the Spanning Sync blog.
  • "Fixes an issue that could occur if two compose windows are open when dragging a file to the Mail icon in the Dock." Actually, I think I ran into this problem with just the main Mail window open.
  • "Resolves an issue in which activating an application from the Dock switches to a different space, even if there is a window for that application in the current space." This has been another annoyance for me, such as when I click on the Terminal icon to bring the command line window(s) in the current space to the front, and instead I get switched to another space.
  • There's a bunch of Time Machine fixes, which I hope may allow me to get backups over wifi to a disk image on a file server working (finally). I use rsync to mirror my home machine's files, but it would be nice to have incremental backups with rollback, etc.
