A suburb of Orlando plans to subsidize 20% of all Uber rides, and 25% of ones that begin or end at a train station. It kind of makes sense that a small city with no previous investment in transit would choose to do this. There is no capital investment required, so they could just set a budget and stop the program for the year if they exceed it. They seem to think it will also help with road building and maintenance costs. I don’t quite get that – you assume people take trips because they need to get from point A to point B, and changing the economics of what vehicles they choose may not affect overall demand or reduce wear and tear. It might even increase demand if people take trips they would not have previously. It could drastically reduce the amount of space needed for parking, and that space and expense could be repurposed for something else. It could definitely cut down on drunk driving. They mention that it could hurt the poor, but I think all you need there is a hotline with operators who can book calls and arrange payment for people who don’t have an internet connection. It could provide jobs for laid-off taxi dispatchers.

Greyhound in the 21st Century
Here’s an interesting article in The Dallas Morning News on Greyhound’s technology strategy.
The 101-year-old company stands at a nexus these days. Uber, car-sharing services and autonomous vehicles will likely thoroughly rearrange ground transportation over the next decade. And young millennials continue their migration to downtown areas — sometimes without cars…
Now Greyhound sells at least 60 percent of its tickets through mobile digital devices like cellphones and tablets, Leach said. And over the next few years, the company wants to become part of a loose urban-mobility network built around ride-sharing and autonomous vehicles…
Despite their Old World aura, buses are a solid part of the modern transportation industry, and Greyhound is still the largest player, with an estimated 31.2 percent share of the market.
Well, if by “Old World” you mean Europe, they have had an efficient inter-city train system for about 50 years. We don’t have that in the U.S. for at least two reasons. First, because we have an enormous investment in a highway system that benefits the auto, oil and finance industries. That system is not optimal by any stretch of the imagination, but now that we’ve built it, we are stuck maintaining it and it would be extremely difficult to abandon it in favor of a better system like an efficient inter-city train network. There isn’t enough money to do both at the same tie. Second, the current approach is further entrenched by our federal political system which gives disproportionate votes and funds to the empty spaces between cities.
Now, if you’re a bus service, you benefit from that sunk investment in the highway system because you don’t have to pay anything near its true cost. Your customers are paying those costs in taxes and blood, but your prices appear cheap to them. Add in a few perks like wireless and clean comfortable seats, and your service becomes a near optimal way to navigate a very suboptimal transportation system.
collateral damage
Trump and Cruz are openly talking about indiscriminate killing of civilians abroad. Which is illegal. You’re not supposed to talk about it. There are really no perfect options when it comes to terrorism. Option 1 would be to only collect information abroad, then play defense at the border and within our own borders. You could argue that is sort of what the U.S. was doing before 9/11. It’s not hard for people to point to pictures of a smoking hole in Manhattan and make a case that is not good enough. Option 2 is scorched earth attacks against entire civilian populations anywhere we think a few enemies may be hiding. This is clearly illegal, although it has happened on a large scale in most wars. That is what Trump and Cruz are advocating. In the middle is pursuing “targeted” attacks abroad, destroying a few houses or groups of people that we think may contain our targets, usually with permission of the government of the host country. This (let’s call it Option 1.5) is the path Obama has chosen. How targeted is it really? Here’s a Guardian article from 2014 arguing that the United States has killed about 27 innocent people for every enemy killed. Most disturbingly, this includes many children. I personally like the idea of doing a really good job with #1. But I think Obama has made some tough choices and I respect that. Let’s not pretend that the more violent options are ever for the benefit of the people in the countries where they are carried out, though. They are about sacrificing the lives of a certain number of (mostly non-white, non-Christian, non-English speaking) civilians abroad, whose lives our government implicitly decides are worth less than the lives of civilians at home (although let’s remember that civilians at home are subject to mass death from gun violence, suicide, motor vehicle violence and lack of health care, which we don’t factor into this equation). I’ll give Trump and Cruz some small credit for saying what they mean and meaning what they say on this one. Listen carefully to what they say, and vote accordingly.
Romney vs. Trump
Here we have the last Republican nominee sagavely attacking the current front runner. It suggests to me that Republican leaders are worried the general election may be a lost cause. Maybe it is time for a rational pro-growth, pro-business party to emerge and leave the intolerant fringe behind. A rational pro-growth, pro-business party could embrace policies like clean elections, a universal health care system that takes the burden off employers, investment in education rather than prisons, a rational guest worker program, and a revenue-neutral carbon tax.
Donald Trump is not a real Fascist, he just plays one on TV
I have been thinking that Trump is basically a psychopath, someone without normal human emotions or morals, who nonetheless has a very keen sense of how to manipulate other peoples’ emotions and morals for his own gain. This sounds bad, and it is. But the silver lining, if it is true, is that although he is appealing to some very ugly impulses in a certain segment of the public now, he would become more moderate if he were elected and had to appeal to the full range of the people. However, it turns out that people said the same thing about Hitler in 1922.
the man’s intellectual property rights
The founder of the Creative Commons license committed suicide after being threatened with 95 years in prison over a copyright violation. The article goes through some of the arguments against standard copyright.
‘Open access’ is an anodyne term for a profoundly transformative idea. Advocates argue that academic research should be made freely available to the world at the time of publication, and that access should not be contingent on an individual’s or institution’s ability to afford a subscription to a given journal or database. Academic authors do not usually write for profit; rather, their work aims to augment the common store of knowledge. What’s more, since the government often funds their research, it’s not a stretch to claim that the fruits of that research should belong to the public. So why should this material be subject to the same access restrictions as a mystery bestseller or a Hollywood film? As with many other inexplicable policies, the blame belongs to a vestigial middleman.
When a university professor finishes a research project, she typically records her results in an academic paper, which she submits for publication in a peer-reviewed journal. These journals—the reputable ones, at least—operate via volunteers, with authors, editors, and peer reviewers all working for free. Nobody gets paid, or expects to get paid, except the publisher. In exchange for the publisher’s services, which include coordinating the publication and peer-review processes, formatting, and distribution, the author concedes the copyright to her article in perpetuity. It’s a simple trade: the academic publisher assumes the financial risk of preparing and distributing an esoteric work for which there’s a limited audience and in exchange retains all the profits that might come from its sale.
In commercial trade publishing, publishers realise profit by selling a book for a relatively low price to a wide audience. Since no wide audience exists for academic papers, academic publishers realise profit by selling them at high prices to the few entities who can’t do without them—libraries and scholars, mostly—which renders these papers functionally inaccessible to the casual or impoverished user.
self-driving cars
Here’s an interesting TED talk on self-driving cars. They are going to save a lot of lives. I think arguments against them like this one on NPR are ignorant at best and immoral at worst. If you can save a million lives a year and you choose not to do it, you are instantly one of history’s mass murderers. Even if there is some bizarre special case someone can cite where a computer might kill someone and a person might not, that’s going to be extremely rare.
Sander-nomics
This analysis of Bernie Sanders’s economic plan by Gerald Friedman at University of Massachussetts-Amherst has made quite a splash, suggesting it could lead to massive improvements in economic growth, unemployment, inequality, and productivity, all while investing heavily for the future in infrastructure, education, and climate change readiness. Bill Moyers.com has a long roundup of the criticism and support from all sides, finally concluding that it is actually plausible using standard, even conservative principles of economics. To me, even if it is only partially true, it just shows how unbelievably badly our economy has been managed over the past few decades, and how unready for the future we actually are.
Meanwhile, the Trump economic plan just doesn’t remotely add up using any known principles of arithmetic.
peak oil is still nigh
This Telegraph article suggests that OPEC expects oil prices to come roaring back relatively soon, and when they do there are worries that the drop in investment caused by the current low prices will make it impossible to keep up with demand. And market speculation can supercharge the up swing when it comes.
Mr al-Badri said the world needs an investment blitz of $10 trillion to replace depleting oil fields and to meet extra demand of 17m barrels per day (b/d) by 2040, yet projects are being shelved at an alarming rate. A study by IHS found that investment for the years from 2015 to 2020 has been slashed by $1.8 trillion, compared to what was planned in 2014.
Mr al-Badri warned that the current glut is setting the stage for a future supply shock, with prices lurching from one extreme to another in a deranged market that is in the interests of nobody but speculators…
The paradox of the current slump is that global spare capacity is at wafer-thin levels of 2pc as Saudi Arabia pumps at will, leaving the market acutely vulnerable to any future supply-shock. “In the 1980s it was around 30pc; 10 years ago it was 8pc,” said Mr Descalzi…
By the end of this year there may be a “small deficit”. By then the world will need all of Opec’s 32m b/d supply to meet growing demand, although it will take a long time to whittle down record stocks.
So to put it in stock and flow terms, there is a big stock built up right now, and demand is less than what can physically be supplied (these are flows), so prices are low. When (if?) the global economy picks up at some point, demand may be greater than what can physically be supplied. The stock will gradually get used up, and as investors start to realize it is getting used up and supply will not be able to keep up, prices will rise, maybe fast. High prices will eventually spur investment and the cycle will repeat. This is how it plays out all other things being equal. But some of the other things are renewable energy, maybe nuclear energy, carbon credits/taxes/caps, maybe approaching physical limits on the big Middle East oil reservoirs, food and water economics, public sentiment, and geopolitics, all of which can shift the economics at the same time fossil fuel technologies and markets are going through their gyrations. Interesting times.
what’s whiter than white?
Here’s an article that is interesting for at least a couple reasons. First, the efforts of the Chinese (government? companies?) to steal the “trade secrets” of U.S. companies. For some types of knowledge, like how to program computers, a lot of the potential economic value to be captured exists inside the minds of people who have gained skills only through years of painful education and experience. Stealing a computer program written by one of these people doesn’t really steal that much of the value, because in order to reverse-engineer and use it you basically need someone just as knowledgeable and skilled as the person who created it in the first place. On the other hand, with a substance or material that has a “recipe”, like a chemical or drug, stealing the recipe does mean you have stolen most of the value. So you can understand why companies that develop substances and chemicals go to great lengths to protect their “intellectual property”. I still think there is a legitimate question though whether it is morally wrong to steal something like this. Developing countries can improve the lives of their people by quickly “catching up” to countries with more advanced technology. Is this wrong? Should they have to buy the knowledge? You can argue that if there are no protections for knowledge, there is less incentive for firms to take the risk of looking for new knowledge, and therefore progress will be held back. But I would ask whether if a country like China did not “steal” the knowledge, would it otherwise buy it or would it just go without. If it is the latter nobody benefits – neither the companies with the knowledge or the people that could benefit from it.
The second reason I find this interesting is that it is an example of an incredibly advanced industrial technology that really has no practical purpose, and yet seems to have immense economic value anyway. The value we place on useless and even harmful things could be a practical measure of our flaws as a species. I was shocked to hear that the filling of Oreos contains titanium dioxide just to make it appear more brilliant white. And whether the product is safe or not, the process involves toxic chemicals that have to be manufactured and trucked or trained around at some risk to the public. I really don’t think I want to be eating that. When a product is useful and there is no readily available substitute, you can justify taking some risk to bring it to market. When it is not useful, there is no risk justified in my opinion. Long-term we should be looking for 100% safe alternatives to toxic chemicals.
There’s white, and then there’s the immaculate ultrawhite behind the French doors of a new GE Café Series refrigerator. There’s white, and then there’s the luminous-from-every-angle white hood of a 50th anniversary Ford Mustang GT. There’s white, and then there’s the how-white-my-shirts-can-be white that’s used to brighten myriad products, from the pages of new Bibles to the hulls of superyachts to the snowy filling inside Oreo cookies…
The basics are public knowledge. First, the ore is fed into a large ceramic-lined vessel—the chlorinator. There it’s mixed with coke (pure carbon) and chlorine and heated to at least 1,800F. “The material inside here resembles lava. This is like running a big volcano,” Daniel Dayton, a former top executive at DuPont, told jurors about the chlorinator in 2014. (Chemours and DuPont declined to comment for this story.)
Hot gas in the chlorinator gets piped out and condensed into a new compound called titanium tetrachloride, or “tickle,” as engineers call it. The tickle is heated again, subjected to various purifying chemical reactions, and cooled. Now a yellowish liquid, the tickle is inserted into a second vessel, called the oxidizer. It’s again heated to very high temperatures and mixed with oxygen; the reaction knocks the chlorine molecule off the titanium, and two oxygen molecules attach to the titanium in its place. The resulting particles are so fine that the white stuff has the consistency of talcum powder.
