Comment Re:Technically C++ (Score 1) 230

// comments were added to the C standard. Not good old ANSI see but still ok.

I haven't looked at the code, but the one thing I usually trip over when having to write pure C instead of C++ that's really mostly C is that everything has to be declared at the top of the function... Always. even some variable you only use in the IF $DEBUG block, I normally declare those in the if $debug block where it occurs, rather than creating a 2nd if debug block at the top of the function just to declare it.

And stuff like that.

      we have something here as exciting as cold fusion or polywater. it seems to violate newtons second law so people are looking for the escape clause. If it's real it's a huge deal because it means the fundamental problem of space travel--- bringing your propellant--- is permanently solved modulo the nitty gritty of making it more efficient.

On the otherhand, like polywater and cold fusion it's likely a reproducible experimental error that's not been identified yet. 3 groups have independently observed it so far.

My guess: it's just ions sputtered off the walls and accelerated or it's attraction towards an induced dipole in the room, neither of which would be exciting.

If the only argument is that Playboy is so bad that the cropped image is indelibly tainted by association, then I guess I'm fine with that - but the logical foundation seems shaky.

subsitute "so bad" with "controversial" and its about right. Playboy is a source of controversy, and anything coming from it IS going to be indelibly tainted by that controversy.

rational assessment of information is usually based on content rather than provenance.

I accept that the objection to the image may not be entirely rational. I also accept that, rational or not, their objection does exist.

I also note that the provenance of the image usually does come up, because its "interesting", and the inevitable recovery of the full nude image by some interested student, and the content of the resulting commentary is usually inappropriate in a computer science class. While the cropped picture itself is unobjectionable it all but inevitably triggers this chain of events.

Between that and the fact that the image itself is not in any way irreplaceable or indispensable it seems logical to replace the image.

Comment why do we need a walled garden? (Score 3, Insightful) 32

What's wrong with the plain old internet that we need this? I'm thinking that the notion here is that by making money by limiting access that they can give people free internet. AOL.com sort of started with the notion of monetizing a walled garden to offer cheaper internet access and it did spread to eventually giving access to the whole internet. But you could also describe indentured servitude in a similar rosie way of giving people opportunities.

Folks have heard me biatch about changes in my own city in the State of Florida -- and changes in the State itself. Basically the response has been (1) progress old man, (2) change the onion on your belt, (3) yelling at clouds, (4) who cares -- it's Floraduh!

However, these changes have been going on in other states.

I've watched politicians promise Eco-improvements with one hand and sell the voters down the river with the other. [For example] We had a massive oyster bed in the Indian River placed off limits to the public for preservation and ecological reasons for close to 20 years. That thing had huge oysters in it and the water in its cove was nearly crystal clear. The local police arrested scores of people sneaking down there to poach oysters and the shores were dotted with piles of empty shells. The cove was absolutely packed with the things, no river bottom exposed. Then, during the Housing Boom, an upscale development went it around it. Since the cove was too shallow for wealthy owners to park their boats at the planned docks behind the cove-side homes, it was dredged. No warning to anyone who wanted to get these delicious oysters. Dredges came in, ripped thousands of them out and disposed of them. The cove is now full of dark water and few oysters, making a lot of folks like myself wonder why we preserved them.

Water use in the state has quadrupled. Florida used to be very swampy, but the water table was shallow. Now, after sucking so much out and changing the lay of the land, plus paving over every square inch they could, we're the capitol of the US when it comes to sink holes. Water shortages began to pop up years ago, where before, we never had any.

Millions of acres of wild woods have been developed, endangering a host of native species of animals we used to have and the amount of fish in the rivers has diminished to the point that you need a license and a fishing season for Mullet -- once so plentiful that it was considered 'garbage fish' and caught mainly for bait. Within the last 40 years, the Indian River has to be closed to shellfish harvesting and fishing periodically during the summer because of massive human fecal bacteria contamination.

The previously crystal clear air of my seaside town now shows signs of grey pollution. They stopped dump burning ages ago, along with burning huge piles of used tires. Land clearing agencies have to use these massive air blowers that surround burn pits to burn stumps and brush with, creating a hotter, less smoke making fires. However, the local traffic, even with more eco-friendly cars, has quadrupled and quadrupled again. Their lesser pollution has, by the sheer weight of volume, has surpassed that which was present in times of less pollution control, when you used to have 'smokers' rolling down the roads.

Major advertising campaigns have convinced the public that instead of one or two cars per family, everyone except the dog needs one, plus a couple of ATVs, a boat and a couple of those fast, small watercraft good for nothing except going fast on the water and making a lot of noise. Prior to that, dirt bikes were the thing, tearing up thousands of acres of wild woods and chasing out local animals for fun. To round things out for the macho man, we have air boats, running on aircraft engines, no mufflers, tearing up the diminishing acres of wild swamps and annoying the crap out of neighbors when the owners 'test' them in their yards.

We have fewer forest fires than when I was a kid, thanks to sophisticated fire equipment -- but then again, the acres of undeveloped woods has fallen by 3/4, so there's less to burn. Where lightening would hit decades old pine trees and forest floors thick with dry pine needles, it hits houses, paved streets, power poles and grassy lawns.

My yard has an 'old growth' pine in it. Around 60 feet tall and nearly three feet around. It was 6 feet tall when we moved in around 1958. Across the street used to be a forest of even older trees, around two miles square. Some reached 100 feet tall. That area is now made up of a couple of housing developments. 98% of the trees are gone.

The main drainage ditch in front of my home, which was shaded by Oaks along the banks, was more like a shallow creek, brimming with clear water, frogs, colorful minnows, several types of turtles -- including the irritable snapper -- gar fish and other freshwater versions. Us kids played in it, sheltered from the hot summer sun. Now it's a deep, sluggish stream of dark water, covered by algae, few minnows and most of the Oaks were removed when the housing developments went in. Their 'salvage ponds' drain into it. Even if I was a kid, I wouldn't want to play in that mess.

Yet according to statistics, we need more homes because rents are too high because people can't buy homes whose prices nearly doubled due to the Housing Boom.

We had a landmark here made by a great old man called Ralph Waldo Sexton, who did much for the community with his wealth and eccentric ideas. The land was deeded to the city with the restriction that it never be town down. The city agreed -- until explosive development hit and a business needed the tiny patch of land to add to it's parking lot. The city had let the landmark deteriorate anyhow (known as Sexton's Mountain) and as the value of the Oceanside land soared, that plot became worth much more than the hand built land mark.

They sold it and it was plowed under and paved over. Adding to the destruction of the beach itself from over development. Even the Great Red Land-crab Migration, that used to cover blocks in hundreds of thousands of the small crustations, covering the land for blocks in nearly a solid wave has stopped.

Their nests on a swampy salt marsh have been plowed under as houses went up and covered every square foot, which means a lot of cranes and other animals who fed on them are gone also. Plus their holes helped the ground absorb rain water, which filtered into the aquifer -- those hundreds of thousands of gallons of which now roll off the paved streets and manicured lawns and harder fill into the salt marsh waters and out into the sea.

Each time a politician enacts an eco-friendly program, he quietly passes two which undermine the efforts of the first and benefits development companies or other businessmen. When we had a good city manager who was not thrilled with explosive development, he didn't last long. Appointed by the Mayor, he was removed and his replacement arrived, all hyper about explosive development.
So, now you all can see the nationwide results -- and it ain't gonna stop anytime soon. We protected the birds -- and they tore down the forests. Gopher turtle nests could stop a development -- until no one noticed them until after the bulldozers had plowed them under. We built a huge, new eco-friendly dump, closing all of the others -- and then they had to sink huge pipes into it to vent the not-so-eco-friendly methane gas, making no attempt to even capture, compress it and use it. (You can smell our dump long before you see it.) Around the 4th of july, dump managers are secretly terrified some kids with fireworks might manage to ignite some of those vapor spilling pipes.

Crime, illness, irritability and cost have soared within my city. We went from a small Mayberry-type jail to a fortress-like prison, plus built a sprawling juvenile facility. Where you could walk the streets at late night with no fear, you need to go in groups now. Home burglaries have just soared. (I even got hit, for the first time in over 50 years.) We had 4 good schools. Now we have about 10 mediocre ones and they have chain link fences around them. Kids are no longer allowed to play on the exercise fields during summer vacation. Shootings are on the rise.

The cost of living keeps climbing. More and more funds are needed to keep the infrastructure going to maintain the city and county, while they keep reducing benefits for the workers who do the actual work. We now spend millions a year on keeping our beaches nice -- something they did for just a few thousand 30 years ago when thousands of folks didn't tear them up and build right up against them.

BTW, rents here are just obnoxious, unless you want to live in a place made up of termites and roaches holding hands. We were also a major citrus provider -- but the majority of the old, labor intensive groves which produced magnificent fruit have been sold and housing developments put in their place. (It takes 4 years of work to prepare the ground for citrus saplings then another 4 years to harvest good fruit. Working in a grove for the summer was almost every high school kids rite of passage. Old, established groves were gold mines.)

I once reported a new Sea Turtle Nest I found on a beach, not wanting the heavy, tractor-like sand groomers (yeah, we have to have those now) to roll over it and crush the eggs. The response I got from the Federal and State agency I contacted was 'what do you want us to do about it?' Yet had I dug up the eggs to move them, cops would have popped out of the weeds to arrest and fine me.

I think the beach groomers crushed the nest.

Comment Very very very poor multi-tab open (Score 3, Interesting) 240

Chrome is truly awful at opening multiple tabs at once on my mac. unbelievably slow loading times compared to Safari. And when a page is loading in one tab, other tabs don't continue to update swiftly. I find this really a weirds because chrome uses a separate process for each tab so one would think they would not step on each other. My guess, wild, is that tabs are contending for some resource like network or GPU and actually slowing each other down. In general I much prefer safari or firefox, but I use chrome because I also own a chromebook and I can't run safari on that. Basically, google is doing the same thing microsoft did to make IE dominant by not allowing other browsers on their platform.

And I can pretty much guarantee than an innocuous headshot photo I take of perfectly normal woman wearing a hat with a feather on it will prove to be far less controversial than a cropped playboy centerfold from the 70s.

Therefore, why not just use the one we already have.

You know why, your just being deliberately obtuse.

I am not being obtuse. I am well aware it is both a common and famous image. I've seen it several times over the years.

But the only real objection to dropping it amounts to "In a perfect world no one would think we should have to".

To that I would say "Grow up". The entire so-called standard image collection is extremely low resolution, poor quality color, and dated. Nobody is really doing real science on it anymore. We have libraries with thousands of equal or better images. People don't pick Lenna for their publication to compare it with old research - people pick her because she's like a mascot.

We can pick a new mascot image. It won't break science.

Lots of sports teams in the US have dropped their traditional names and selected new mascots over the years due to being inappropriately offensive to native americans. Even now The Washington Redskin's owner is kicking and screaming to hold onto that name, but the writing is on the wall; and its only a matter of time until that gets changed too.

Lenna is a central story in computer imaging history and that's fine. Let it just become history. It's not a appropriate photo anymore, it never really was.

This is a school that is supposed to be developing kids to do advanced work in the field.

So, not using the image in a high school assignment will somehow diminish the students education? Absurd.

This really doesn't need to devolve into politics. No question the world is not remotely fair.

Do the course work, and stop worrying about the people around you. They don't matter. Do the work, get your grade, pass the course, and move on. That is what growing up is all about, right?

You've essentially said the students shouldn't question authority or express themselves when they see misogyny or injustice etc. Yes they will learn the world isn't a perfect place -- that is part of growing up. But trying to change it, and changing what you can is a part of growing up too.

The point? My version wouldn't be a crop of a nude woman that would belong to playboy. There would be nothing the least bit controversial about it, and it would have all the same technical merits in terms of suitability as a test case for an image processing alogorithm.

I don't see how continuing to use the image helps them, though.

What does what "you see" have to do with it? Frankly I agree with you about the image itself. I am not personally offended by it.

But surely you accept the empirical evidence that many other people do find even the idea of the use of a centerfold image lifted (even cropped) from Playboy to be inappropriate in an academic setting.

I see it. I even agree its inappropriate. Its certainly not something I'd knowingly do if I were selecting images to create a sample set of images for high school course.

your right. it meets a technical definition of censorship. I withdraw my objection based on it not being censorship.

However, even if I accept its "censorship", so what? There is nothing wrong whatsoever with not doing something that pops into your head because you realize other people would not appreciate it, would not understand, or would be offended by it.

There is nothing wrong with that. Yet you make out like its universally wrong. That's ridiculous.

Or are you really suggesting that a high school computer science teacher is showing good judgement if he goes through his porn collection, crops a bunch of the images of various porn actresses and provides those as his sample data set, with attribution. (Because not providing proper attribution is itself academic dishonesty.)

Does he have the right to do it? Sure. Because otherwise censorship right?

But does everyone else have a right to tell him he's an idiot, and refuse to do the assignment, and complain the administration that they feel the assignment is completely inappropriate, and demand he be replaced with a teacher who doesn't make decisions like this. Why yes, they can, because if they couldn't that would be censorship too. And around we go.

Some measure of reasonable self-censorship is part of normal social lubricant. Whether or not you personally feel the image is offensive you are aware that it controversial. If you select it knowingly you provoke controversy. If if you provoke controversy... then own the consequences.

While you have the right to offend. Other people have the right to be offended.
