3:08a - Tax Reform: Immediate Feedback
Do people behave more responsibly when they feel the consequences of their actions immediately?
Matt McIntosh proposes a tax system based on this idea
Here’s a tax reform proposal to try on for size: start with a graduated income tax (or consumption tax with negative income taxes a la Arnold Kling, either works) without any special loopholes, deductions or exemptions. Index the tax to an equation so that there’s a smooth curve rather than these idiotic “leaps” in marginal tax rates which are the cause of much frustration and economic distortion.
So far it’s sensible enough (though not very interesting), but now here comes the smart bit: the equation for the tax will have two variables, one being the individual’s income (or consumption) level and the other variable being indexed to the size of the federal budget. The tax will automatically slide upward or downward every year according to the budget, getting lower when spending is down and higher when spending is up. Thus the tax rates will be directly tied to Congressional spending, increasing automatically for everybody when Congress spends.
At first this may have you aghast, but stop and think a minute about what it would mean: every time Congress wanted to spend on something, they’d have to immediately consider the negative effect this would have on their popularity, since everyone’s taxes would go up with spending. It would make the voters directly feel the pain for the federal spending they support. Ceteris paribus, over the long haul this should lead us to precisely the amount of spending that most of the public wants, which I’d guarentee would be less than we have now once they feel the costs of it immediately.
Now of course, this is not my ideal world. But it’d be a damn sight better in the long run than what we have now, and is really the only way to get government spending down and keep it down. It’s all about installing a fast-acting feedback loop, making people feel the cost of things quickly rather than diffusing the costs and kicking the can down the road all the time. I introduce this idea because 1) the graduation of the tax should make the lefties happy, 2) the fiscal responsibility it would impose should make the righties happy, 3) it’s relatively simple to explain, and 4) just about everyone can agree that it’s better than the current ludicrous tax scheme.
In theory, at least. In practice, well, nobody ever went broke betting against common sense winning out on Capitol Hill…

8:23p - RSS and information channels
email webpages phone
How hard would it be to create a unified format and language that translates (both ways) between any pair of formats / media? Could we extend RSS for such a purpose?
The advantage is that current filtering is format-based: i.e. all your email is in one place, all your voice mail in another, whereas it would be much better for things to be subject-based or project-based (i.e. bills to pay in one screen, university-related research in another screen, etc) in a goal-subgoal tree.
An analogous problem is that windows in Windows tend to be grouped by application. This is (poorly) solved in Unix, by using several Desktops.

LJ notification should work in terms of a blog-wide RSS: for any new comment in my blog, make an RSS entry, and set up an RSS->email agent to notify when comments were made. Also, for any reply directed to me, or any new comments in a thread that I choose to subscribe should become items in the RSS. Likewise, a smart (possibly collaborative) filter could deliver interesting blog entries.
I'd like to make a bot to handle all my LJ notification for me. This seems quite feasible... if perhaps inefficient without LJ's collaboration.

Btw, what about these ideas? phone call * leave a voice mail as an MP3 (I know of no VoIP service that supports this) * email -> voice mail (voice synthesizer)

10:49p - problem with the news
Any Americans here who visited Brazil since 2004? If so, were you fingerprinted?
The latest news on this is almost 2 years old. This is a serious information problem. It shouldn't be hard to ask an American who traveled to Brazil recently, and yet we don't know how to do this.
Why don't we have anything more recent? Because neither "Americans no longer fingerprinted in Brazil" nor "Americans still fingerprinted in Brazil" makes a good headline. With current technology, this is a very hard information retrieval problem.

11:15p - solutions to bad weather
Why does bad weather make everyone miserable? Surely the greyness can be overcome with anti-depression lights, and wetness can be prevented with the right clothing. Given this, people should not be reluctant to leave their homes.
Tomorrow I am going to look for some comfortable rain apparel to buy: hat, jacket, pants. It makes an umbrella unnecessary. Hopefully they would be comfortable enough to wear all the time... if they aren't, I can always spray-coat all my regular clothes, right?
The problem, it seems, is that impermeable clothes make you hot very quickly.
In dry weather, is wearing an impermeable plastic coat any different than a thick woolen one?
"Impermeable clothing does not “breath” and thus greatly increases an individual’s susceptibility to heat-related illnesses. Clothing acts as a barrier that prevents evaporative cooling. Many synthetic fabrics reduce the absorption and dispersal of sweat needed to achieve optimum heat loss by evaporation." source
So impermeable clothing prevents heat loss by evaporation, while thick woolen clothing prevents heat loss by conduction... what left? Convection and radiation.
Maybe rainy weather is inherently uncomfortable because you can't lose heat by evaporation, since the air is saturated... so you're going to be muggy.
