Comment Re:Breaking news! (Score 1) 148

The article shows a picture of Breakout, and tends to focus on the wrong things entirely... especially the title, trumping that "computers can beat humans". It's fairly impressive that computers can learn the rules of a simple videogame on their own and perform well, but beating humans is not exactly an apples to apples comparison, because while we can formulate strategies to maximize points, we're also prone to making simple mistakes due to our much poorer reflexes and coordination.

Exactly. The article talks about the "advanced strategy" of tunneling a hole through to bounce the ball of the back wall. But that's only a useful strategy to make up for someone who doesn't have the reflexes to bounce the ball with their paddle, or can't be bothered. If the program had good reflexes and didn't get bored, then tunneling in breakout isn't any advantage.

The last quarter or so of the patterns deal with interior space, but i think you might find it problematic to just apply them in isolation.

The patterns are meant to be applied in order, from largest effect with least detail, to smallest effect and highest detail.

So, for instance, if you take room that doesn't have "light on two sides"

there may not be much you can do, interior design wise, to save the room, without first trying some of the suggestions he has for how to deal with the lack of windows...

One other AC posted this, but it will probably stay buried at zero.

If you're interested in why some spaces feel nice to you and others don't, there's a series of books you want to read, by "Christopher Alexander"

The first one is "The Timeless Way of Building". The next is "A Pattern Language"

This guy was writing about the human factors in architecture -- why certain spaces make all people feel good, and how that developed over human history, and how it's largely been lost in modern architecture.

His next book, "A Pattern Language", enumerates 253 patterns his team rediscovered that help resolve social problems in architectural spaces.

The problem he noticed is that people could understand if they felt good in a space or not, but it was difficult to predict ahead of time if a building would have this quality or not. And that's obviously a huge problem if you want to build things that people love, because buildings are expensive and stay around a long time. Just cloning old buildings that people like doesn't quite do it either - because people didn't really understand what made those spaces great.

This series of books is what the Gang of Four looked at, and one of them said "hey, this applies to building software also - when the problem looks like this, there's a pattern that can be implemented many different ways to address that problem".

Thus, the design patterns movement in software was born.

If you're at all interested in houses, cities, planning, design, etc, I really recommend the books.

However, read them before you buy/build your next house -- not right after you just moved. You'll start to find explanatinos about where you currently live that explain why you don't use or don't enjoy certain things, and you'll be frustrated and want to start changing things :)

You should consider the business model of slashdot. How does slashdot make money? I suspect page views are part of it.

If i were running slashdot, I'd be able to tell you, based on over a decade of historical data, which types of articles generate the highest ad revenues. I'd make sure those articles appeared as often as possible, and I'd look for feedback effects to make sure I wasn't over doing it.

If you want to know why slashdot has lots of articles in Elon Musk, Tesla, Gender in CS, and Microsoft, it's because those stories bring the clicks, commenters, and critically, page views.

Comment Re: Electric cars work great in an urban landscape (Score 1) 215

It was not so long ago that rural residents exceeded urban residents in the US. While the balance has flipped, it has not dramatically done so.

I live in a rural area and when I go into the office it is a 20 mile one-way trip (that takes only 20 minutes, door to door). If I run any errands while I am in town I need to plan for at least 50 miles of drive on a charge. Given that it gets bitterly cold here (-30F is not uncommon), I wouldn't feel comfortable running a battery pack that didn't have a significant buffer above that range. Also, given that the posted speed limit is 75, and the roads are often empty, my actual road speed can be much higher than the 55-60mph that range testing is conducting at. Also, wind speeds here are often 30mph or more, so the car may be moving through the air at a 100mph or more speed equivalent. Drag increases exponentially with air speed.

When driving in winter, rear defrost, seat heaters, and front defrost will all be running at maximum.

The bottom line is that I don't think I could reliably do my daily commute on something approximately rated for my actual expected round trip mileage. The Leaf is rated at 70 miles at 55mph with intermittent AC usage. That's not enough margin for me to feel comfortable.

I have driven a Tesla 85 and it is simply magnificent. I'd be willing to experiment with the Tesla 60kw and I think it would reliably meet my normal needs, but any lesser EV I have no interest in.

Yeah... that'd all be great if it were true... but the recent OpenSSL fiasco(s) show that there's significant non-variety in core things (because code-reuse is a good idea on things like crypto, maybe...) but those core things are continually and sometimes dramatically and fatally broken.

The crud layers on top of the core things don't add value when the core is broken.

Comment Re:Emergency probably has legal meaning (Score 1) 120

When a bill declares that the measure is an emergency measure, it means that the changes enacted by the bill go into effect sooner than the typical implementation timeframe for legislative changes.

E.g. if the normal delay is house->senate->governor->july 1st of next year, an emergency measure might be house->senate->governor->15 days

The specific timing varies from state to state.

There are a handful of bills being introduced in my state right now that list "AND TO DECLARE AN EMERGENCY" in their bill abstract, which is terrifying until you read the bill text and then understand what the little postscript at the bottom saying "This is an emergency measure" actually means. (I had to ask)

Comment Re:Ask Japan... (Score 1) 309

I really like Hydro power, but

1) you can't simply put hydro power generation where you like it. Hydro power needs established geophysical features in order to work. And, as luck would have it, the things that make a location a good candidate for hydropower also make it a good candidate for farms, valuable waterfront properties, wildlife preserves, public parks, etc etc.

2) Believe it or not, it's not just nuclear power that environmental whacktavists have succeeded in choking out. There are dams that have been torn down to restore animal habitats, for instance. Building a small nuke plant is massively less environmentally disruptive than building large scale hydro.

The chief problem, in my view, with hydro is that you cannot put hydro plants out where people won't care. You have to put them where the water is, and often, people have reasons for wanting such natural water features left alone.

You can put a nuke plant anywhere you like - in a submarine, on a space craft, etc. You bring the fuel to it, you move the waste away from it. The nuke plant I think is fundamentally better adapted to the realities of power generation if for no other reason than fuel source portability. In this way, it beats hydro, and, to a large extent, solar.

My female colleagues and managers are WITHOUT EXCEPTION great software engineers. I wonder why your workspace is so bad?

It's hard to blame it on "the women" because then you'd have to explain why places like my workspace doesn't suffer. So it must be something else. Any ideas?
