Comment Re:Overstating cat's role? (Score 5, Insightful) 110

Cats can wander around without arousing much suspicion. In residential areas, that includes going into front and back yards. In commercial areas, that includes going into secured lots. In that respect, cats would be able to perform better. Of course, that leaves the issue of getting cats to explore areas that you're interested in in the first place.

Another often overlooked advantage of vim is continuity. Thos of us who learned vi because it was one of the best editors at the time can still use those skills. When the need arises, we can also build upon those skills with a modern implementation. In all likelihood I'll be able to make the same claim 20 years from now, when most (if not all) of these upstarts will be long forgotten.

New and improved is great. Constantly relearning skills that you already have, to adapt to new interfaces, isn't so hot.

Writing by hand remains an essential skill, and will continue to be an essential skill for the foreseeable future. It is true that it is no longer the domain of people who author reports or books, corresponding with friends and businesses, and many other areas. Yet it is still used extensively for note taking, completing forms, and in many situations where it is easier to use the pen than the keyboard (diagrams, equations, etc.).

In time, that may change. In time, it will probably change. Yet I am getting quite tired of reading the handwriting of adults that wouldn't pass the muster of a grade 3 teacher.

MPW did something similar, only they used their own command set. This had a unique benefit: the output from MPW utilities often included commands that could be executed by clicking on the line with your mouse and pressing enter. It worked very well since the utilities themselves generated those executable commands, and users could extend upon the system with their own utilities. (MPW was a development environment after all.)

Here's the thing though, Xiki cannot do that because its trying to use existing Unix utilities and development tools. While the output from that software is usually intended to be used by other software (e.g. via pipes), it is rarely intended to be used by the shell itself. That means Xiki needs to understand how to interact with each piece of software. As a result, it will end up being an unwieldy mess of plugins and unsupported commands.

Don't get me wrong. The Xiki demos were doing some pretty neat and fairly useful stuff. In that sense, it is a success. The problem is that you'll never be able to use the full power of the metaphor because the software that it interacts with was never designed to interact in the way Xiki needs it to.

Calculators didn't present the risk of undermining mathematics. (Some people suggested that calculators would reduce people's proficiency at arithmetic, but it calculators didn't create invalid results.) Electronic voting does run the risk of undermining democracy. Even if the systems were secure with respect to voter privacy and vote tampering, the mere suspicion could influence people not to vote to change their vote or the question the results of an election.

Comment Tax, don't ban ... (Score 1) 532

I'm not sure if it's appropriate in this case, but I'm far more in favour of sin taxes than outright bans.

Like I said, I don't know if I'm in favour of that in this case.

On the one hand, it is clearly a harm that a person is doing to themselves if it is even a harm at all. (On the latter: there are days when someone may drink excessive amounts of sugar water, even though their nutrition is good over all. Do we really want to place restrictions on that?)

On the other hand, poor nutrition is a huge social problem that industry contributes to. Even if you ignore their attempts to persuade people to make unhealthy choices through advertising (and yes, the bulk of advertising seems to be geared towards unhealthy choices), you also have to consider product availability. Consider the bulk of grocery stores. While they do offer plenty of healthy choices, the bulk of the floor is dedicated to prepared foods (including drinks) that are chock full of sugars. Consider eating out. Many places offer nothing beyond sugar water and coffee. Even the things that pretend to be juice aren't terribly different from soda, outside of the lack of carbonation. When they do offer proper juice, it typically has sugar added -- though certainly not to the degree that non-juices have. So if you don't have a healthy choice, people are usually going to make an unhealthy choice.

Comment Re:So now we can steal their IP? (Score 5, Insightful) 86

I highly doubt that the solution is to abolish patents, though a great deal of patent reform is certainly necessary.

What we should de doing is looking at when patents are and are not useful, and modifying patent law accordingly. A lot of the analysis should be fairly straight forward to do. Patents themselves have to be registered, so we have records. When patent disputes are taken to the courts, we have records. Many, if not most, of the businesses that license patents have to publish financial reports. (Again, there are records.)

Questions can be asked and answered through all of that data. We can look at the optimal duration for patents for different sectors. We can look at what types of patents stimulate innovation, and what types of patents stifle innovation. We can even look at licensing practices in an effort to reduce the burden that patents place upon the courts.

It isn't all or nothing. Patents are neither entirely good, nor entirely bad. We simply need a way to separate the good from the bad so that we can keep the former and discard the latter.

Comment Re:AP Statistics isn't really computational thinki (Score 1) 155

The AP curriculum has probably changed over the years, but my AP computer science courses were computer science course. Yes, we learned a language. Yet we went beyond that to learn how languages (in general work), how particular algorithms work, as well as how to design and implement various algorithms. While the projects may have been boring by modern standards (i.e. we didn't frame the course in the context of games), the actual content and instruction was exciting.
