"Lord of War" and the land of the ...

Lord of War (2005) came to the top of my Netflix queue this week; it has been on my various to-do lists since February 2008 when my brother-in-law recommended it to me during my trip to New York. It's not the feel-good-movie-of-the-year, but it's got some meaty food for thought:
The film was officially endorsed by the human rights group Amnesty International for highlighting the arms trafficking by the international arms industry.

DISCUSSION TOPICS
- Weapons trading, civil wars, guerilla warfare, cold wars, the end of the Cold War, redistribution of wealth, the CIA, peace, Africa, AIDS, politics, Pacifism, chaos and anarchy, greed, immigration, the Russian mafia, conflict diamonds, massacres, prostitution, war, bureaucracy, arms embargoes, drug abuse and addiction.

MESSAGE
- Greed and power corrupt. Violence is in our nature.
Lord of War [2005] [R] - 7.8.10 Kids in Mind
Nicolas Cage once again plays the amoral main character and for most of the movie, we see through his rationalizations and we can see what's coming to him. We're right there with his wife when she says that while she failed at a lot of things, she'll never go so low as he has.

But then-zing!-we learn that we, as U.S. citizens, are party to what he does, as it's a byproduct of U.S. foreign policy.

And it's not just the U.S.:
A brief postscript notes that, while private arms dealers do conduct a lot of business, the five largest arms exporters – the United States, the United Kingdom, Russia, France, and China – are also the five permanent members of the United Nations Security Council.

If that's not bad enough, there's more to see. Inside Job, called An extraordinary documentary about influence and government by Lawrence Lessig, is now playing in KC.

Another meeting just snuck up on me while coding in my cube

My new job is much more on the maker's schedule than the manager's schedule. Work at W3C basically consisted of preparing for and participating in several meetings a day with people all over the planet. Now I'm mostly coding away in my cube, and the little reminder icon at the top of my screen is not enough to break me out of it. (I'm trained to be interrupted by the buzz of my mobile phone, but sync between the enterprise calendar and android unreliable. Sigh.) Having people physically grab me means I don't miss the meeting, but it doesn't give me a chance to properly context switch.

I don't use a laptop (mostly by choice) so access to the Web depends on either pre-filling a paper cache (printing stuff out) or using the pc/projector in the meeting room. The latter is often more disruptive to the meeting than it's worth.

Fortunately, somebody else had printed the web page that I had prepared for today's meeting. And the group leader uses a laptop, so we had two copies.

Part of my preparation for the meeting was to question whether we needed it at all, having recently read Tantek's thoughts on meetings. I thought the technical issues were pretty straightforward and we should just let the developer get on with it and deal with problems as they came up. But it turns out that some of my understanding of the requirements was wrong, and even in the parts that were right, brainstorming led to solutions that were better than the approach I expected development to take.

Meeting discipline is important. My approach to the risks was finely honed over a decade of remote work, but now that we can get together in the same room without getting on airplanes, I'm learning it all over again.

A VoIP puzzle

Our home phone service is provided by a VoIP provider, ViaTalk. I have a VoIP client, sipdroid, on my smart phone. When the phone rings and caller-id shows a call I want to take, I'd like to take it on my smart phone. Is this too much to ask?


Evidently so: when I have my smart phone register to answer calls on the home line, incoming calls no longer ring the land-lines in the house. SIP is complex enough to make configuring softphones a nightmare; for all this complexity, it can't register two devices for the same phone line at the same time? Or is the limitation somewhere else?

p.s. If anyone knows how to solve this puzzle, I'd also like to forward caller ID to my phone as instant messages; I'm happy to write a little SIP to XMPP proxy in python, given the necessary clues about the protocol.

chorded keyboard for android, anyone?

I don't miss a physical keyboard when I want to text "Did you feed the dogs?" messages. Swype and voice input work better.

But anything much longer than that involves editing, which is really hard to do without chorded key combinations such as shift-select with arrow keys and mod+x/c/v/z for cut/copy/paste/undo.

The web browser and photo browser make good use of multi-touch. Why isn't there a keyboard alternative that uses it for chorded input?

Putting the HTML5 genie back in the bottle in the name of web security?

There's a lot of wisdom in what Crockford continues to say about HTML5 and web security:

The HTML5 proposal does not attempt to correct the XSS problem and actually makes it worse... The fundamental mistake in HTML5 was one of prioritization. It should have tackled the browser's most important problem first. Once the platform was secured, then shiny new features could be carefully added.
It makes a lot of sense in theory, but I doubted the practicality of it in a Dec 2008 item:
after wrestling with the patchwork of javascript security policies in browsers in the past few weeks, the capability approach in adsafe looks simple and elegant by comparison. Is there any chance we can move the state-of-the-art that far? ... it seems an impossibly high bar to reach, given the worse-is-better tendency in software deployment...
He acknowledges the difficulty, to some extent:

HTML5 has a lot of momentum and appears to be doomed to succeed.
Chuckle.

He goes on to recommend to suspend the current HTML5 activity now:
I think the wiser course is to get it right first. We have learned the hard way that once an error gets into a web standard, it is really hard to get it out.
Would that standards had so much impact. It's true that once a W3C Working Group is in motion, it's difficult for the organization to decide to stop it. But that's really only tangentially related to the heart of the problem: shipping code. Much of the web development community and many of the users have their fingers on the shiny new features; who's going to go first in taking them away?

Ditch cable TV? Yes. Build an HD DVR out of old PC parts? Maybe not.

This item was supposed to be entitled Ditching cable for netflix/wii, broadcast HDTV, and a DIY PVR. After watching the digital media marketplace and technology for years, I convinced my family it was time to go for it this summer. We're close, but due to one critical breakdown in my research, we're not quite there.



  1. Cancel TV part of double play TV+Internet subscription, reducing it by ~$60/month.

    We never did go for their triple play with phone service; I signed up for VoIP with
    ViaTalk when we moved houses a couple years ago, and we've been pretty happy with it. While only the cable company can do on-screen caller-id, I'd rather have stuff like email and SMS notification for messages, for less money. Try it, and tell 'em Dan sent you (referral code 47340A17).
    Check.
  2. Set up TV for broadcast HD TV.

    The salesperson at Best Buy recommended a $60 active antenna, but we went for the $30 RCA ANT1400 Multi-Directional Digital Flat Passive Home Theater Antenna (White) and it works just fine, even in the basement.
    Check.
  3. Subscribe to Netflix.

     I wondered about the quality of streaming movies, and the first one we tried was pretty bad. We were planning to buy a Roku box, but first we tried it on my laptop, a MacBook Air, hooked up to the TV. Big mistake. Turns out these things have a well-known cooling problem, and "The problem is aggravated by system-intensive tasks such as video playback". Then we remembered Netflix started supporting streaming to Wii consoles, and we have one of those. It seemed too good to be true, but it's not. It's just like watching a DVD, as far as I can tell. We may or may not ever get a Roku.
    Check.
  4. Cobble together a PVR out of old PC parts.

    My wife misses some cable-network-only shows, but for the price of a new HD capture card (around $80) it looks like we should be able to timeshift broadcast favorites such as Survivor and Big Bang Theory.
    That was the theory, anyway.
I thought the hard part was video capture, encoding, and recording. Sucking in HD video through a USB gizmo seemed too good to be true; plus, the norm with USB gizmos is that half the smarts is in a proprietary, Windows-only driver.
