rating news

I have an idea that maybe others have already thought of, but I haven’t seen it proposed (or implemented) in exactly the form i am thinking of. With all the newfound concern over “fake news”, misinformation, and disinformation, alongside good-old-fashioned government and corporate propaganda (which to its consternation is having some trouble competing with the former), I don’t see why news stories couldn’t be rated or certified as reliable by independent third parties. That is, you could pull up a news story from any of a number of outlets and see that it has the stamp of approval of a particular organization, say the Associated Press or the United Nations. Sites like Politifact and Snopes sort of do this now, but they aren’t rating individual stories. Any organization could create its own rating system, but at least people could choose a rating system they trusted and then either filter their search results or simply have the ratings they are interested in displayed, perhaps in a browser plug-in. It wouldn’t be perfect because it would give people way of filtering so they only hear what they want to hear, but at least we would be doing this explicitly rather than having hidden, amoral, profit-seeking algorithms decide behind the scenes what we see or don’t see.

the body count from Fukushima

This article has some stats on casualties from the tsunami and nuclear meltdown in Japan following the 2011 tsunami. I don’t want to trivialize the tragic loss of life here, just highlight some stats that were surprising to me.

  • deaths from cancer linked to radiation: 1, a worker responding to the disaster on the Fukushima site as it was occurring
  • suicides: 1 (mentioned in this article)
  • radiation-related illnesses not resulting in death: 4
  • deaths while being evacuated from hospitals near the disaster: 40
  • deaths caused by the tsunami: 18,000
  • people displaces from their homes by the disaster: 160,000

Overall you have to say it is great that people did not die in large numbers from radiation poisoning or cancer. People probably contracted cancer from smoking and not wearing enough sunscreen in greater numbers during the disaster. But if you want a gloomy way to look at it, at least for me a nuclear meltdown is now a less scary thing and a “thinkable” event, and that might not be good.

the old sucking the blood of the young?

There is grisly research where a young mouse is sown together with an old mouse and their blood vessels are connected. This seems to benefit the old mouse. And no, I haven’t watched “human centipede” and I have no desire to, although I did find the South Park parody of it moderately funny.

Beyond the stupidity of human centipede, you can imagine a mad dictator or Bond villain somewhere forcing people to be blood donors against their will. A more benign version would have biotech firms trying to synthesize whatever it is that makes young blood good, or possibly using stem cells to make a young version of a person’s blood. What if a version of me could be created that was just a bag of meat with no nervous system, and pumped out blood that kept me alive? That seems creepy but not necessarily unethical. Add a brain and keep that person sedated or otherwise detained against their will, and that would clearly be unethical (not to mention basically the plot of The Island.)

smart drugs

This BBC article talks about how some people are using amphetamines like Adderall and Ritalin to stay focused and motivated in high pressure jobs. It clearly works, at least for short periods of time. It is not clear whether it can work longer term, because people may either need a significant recovery period to recover from use of the drugs, during which they are less focused and motivated than normal, or else they may become addicted to the drugs. But the article also points out that the new drugs are not qualitatively different from using coffee to stay focused and productive – it is just a matter of differences in degree and chemistry, and coffee has proven to be safe and even beneficial to most people.

half the world’s power from the Sahara

There’s a big idea to provide half the world’s energy from solar panels in the Sahara desert, using the actual desert sand as a raw material to manufacture the panels. An interesting article in Science says that wind and solar farms on such a large scale could actually change the local weather drastically by altering wind and surface temperatures, ultimately increasing rainfall and allowing more vegetation in the desert.

In this study, we used a climate model with dynamic vegetation to show that large-scale installations of wind and solar farms covering the Sahara lead to a local temperature increase and more than a twofold precipitation increase, especially in the Sahel, through increased surface friction and reduced albedo. The resulting increase in vegetation further enhances precipitation, creating a positive albedo–precipitation–vegetation feedback that contributes ~80% of the precipitation increase for wind farms. This local enhancement is scale dependent and is particular to the Sahara, with small impacts in other deserts.

Could this work on Mars? I guess not, because you don’t have the water vapor in the atmosphere to begin with. Unless you get that alien ice breaker thing from Total Recall (the 1990 version, again, I don’t recognize the 2012 version’s right to exist) – why do I keep coming back to this movie?

Ford signals self-driving car’s “intent”

Ford is trying a set of blinking lights to help pedestrians understand whether a self-driving car is likely to stop or run them over. Somewhat interesting, but really I think the legal responsibility needs to be on the car’s owner/programmer and not the pedestrian. If this saves a few lives by preventing a few otherwise unavoidable crashes it is a good thing. If it creates an excuse to blame the victim, it is a bad thing. In recent U.S. history at least, the situation between driver and pedestrian has almost always been the latter.

A back-and-forth white light means the car is yielding. When the car is about to go, the white light quickly blinks. Ford said it’s trying to find a way to communicate that doesn’t use text.

Once cars are machine-driven, any pedestrian-driver communication gets a lot harder. So how does a woman walking or a kid biking check in with a car to know it’s safe to cross the street?

3D model builder for construction sites

Here’s a technology to build 3D (digital) models of what is happening on construction sites over time using data from cameras mounted on workers’ helmets. If you have a 3D model of what is supposed to be built ahead of time, you can imagine this providing the chance to compare what is being built to what was planned, giving you the ability to catch and correct mistakes in real time.

construction productivity

The construction industry has languished in terms of productivity growth for decades. But there are ideas, some of which are mentioned in this white paper from UK firm Balfour Beatty. Many are organized around the idea of prefabricating as many components as possible offset, then bringing them in for assembly. Another way of looking at it is that construction is basically a form of (inefficient, risky and very site-specific) manufacturing, and can try to learn some lessons from other manufacturing industries.

…we know this is an industry that lives on thin margins, is plagued by time and cost overruns and inherently operates in one of the higher risk environments of any sector – risk in terms of cost, time and, above all, human safety. But do we also think of this as an industry with one of the largest opportunities of any sector to transform its model? Can we think of many industries where the size of the prize is to shift 25% of current output to a solution that radically improves speed, quality and safety – all while creating (not destroying) jobs?

Today a new generation of industrialised construction methods, including offsite and modular building techniques, are increasingly being recognised as the best way for the UK construction industry to boost productivity and plug skills shortages. And moving to these methods drives better outcomes for all stakeholders: for the customer, reducing onsite construction times and waste; for the construction supply chain, by improving quality, repeatability (and
therefore output) of infrastructure; for the workforce above all, by raising safety performance and securing long-term employment.
