The problem is that the idea of making information available to the general public has been tied to the particular computer systems used to store that information and that doesn't really work. There are lots of problems, but the main ones are: The information that is made available can depend upon who or what is accessing the information. This is built into the way web servers are configured. Just because one person sees a certain page on a web server there is no particular reason to believe that another person accessing that server from another device will see the same thing. The fact that the information is stored on one particular web server means that that server is a single point of failure in the delivery chain. If your web server is down nobody can see the information on it. To disseminate information widely requires a large amount of bandwidth and correspondingly a large amount of server resources. Access to the information depends crucially on having network access to the ...

Dartmoor is a man-made desert that's deteriorating because of poor land-management and overgrazing. It currently contributes less than 3% of England's total food production. The Dartmoor National Park is mostly privately-owned land. See the Dartmoor National Park Authority web page on Land Management : Land within the National Park is not nationally owned, as in many other countries. All land within the National Park is privately owned. On Dartmoor there are a few major landowners such as the Duchy of Cornwall, South West Water and Forestry Commission, but the rest is owned by a myriad of small landowners. The National Park Authority is also a small landowner, owning land at Haytor Down, Holne Moor and Plaster Down as well as other smaller sites. The National Park Authority works to influence land management through partnership and agreement with landowners, farmers and commoners.   Subscribe to Leave Curious .

I'm sure there is, but the problem is how you convince people it would be worth doing. Here's my 10 cents: Start at the top by defining a language to describe the gross features of the kinds of data the apps are meant to manipulate. These will be things like message forums, threads, messages, user profiles, preferences, user signup and login etc. Then use another language to take these high-level descriptions and define user-interfaces for accessing/altering them. These include status bars, popup notifications etc. This would be a process calculus , allowing you define timers and actions taken when certain events occur. Then for each computational platform, compile those descriptions into machine code on the fly. To do that you will need a whole hierarchy of device driver type information (Interrupts, DMA channels, bus events etc.) and some structure which defi...

 See Technology Connections on What You'd Think Was Fundamental to an Information Society . Terence McKenna on Trading With Aliens (Santa Fe, NM 1990): Regarding his opening remark, see the Encyclopedia Britannica entry on The War on Drugs : The U.S. Congress passed the Anti-Drug Abuse Act of 1986, which allocated $1.7 billion to the War on Drugs and established a series of “mandatory minimum” prison sentences for various drug offenses. A notable feature of mandatory minimums was the massive gap between the amounts of crack and of powder cocaine that resulted in the same minimum sentence: possession of five grams of crack led to an automatic five-year sentence while it took the possession of 500 grams of powder cocaine to trigger that sentence. Since approximately 80% of crack users were African American, mandatory minimums led to an unequal increase of incarceration rates for nonviolent Black drug offenders, as well as claims that the War on Drugs was a racist institution.

I'd never heard the term before!! This diagram showing the sum of the first n consecutive odd numbers equals the square of n reminds me of an idea I once had about diagrammatic proof. The idea is that you can do diagrammatic proofs from the top down and they can be quite as rigorous as proofs by induction because the diagrams are no longer limited to a finite number of cases.

This is a problem caused by a new device used on modern jet engines which use large fan blades to achieve better fuel efficiency. The device automatically reduces the load on engine bearings when a fan blade is broken. It does this by dumping the engine oil into the air intake,...  Not sure why that helps, except perhaps to shut the engine down faster. But in the 737 MAX the resulting combustion products when the engine starts to burn oil enter the cabin and the cockpit through the pressurised air intake. The oil may have additives which make for a serious health risk to anyone who inhales this smoke. I haven't watched all of this video, but it also highlights a problem of how to carry out emergency checklists when the conditions affect the crew's ability to actually follow the list because, for example, the smoke is so thick that they can't see the flight instruments!
