Wouldn't it be nice if the original under the blacked out area could be compressed and then put somewhere else in the image.
It would be much easier if one could just use an algorithm which just displaces the pixels and then forget to randomize the displacement. This could look much more innocent than the above.
That black area has so little expected channel capacity that hiding anything in it is kinda difficult.
Unfortunately the code for the blacking out can be made so small that it is tough to hide anything in it, unless ppm offers some ways to add complexity in some innocent way.
I wonder what means of deciphering the hidden area are allowed, i.e. can I write another program to get the kitty face information back?
That is a really cute picture. I wonder what it is thinking.
You weren't able to come up with an obituary for Albert Hoffman a few days ago and now you are trying to foist this abomination of a language onto us. This site is loosing its edge I'd say.
But I hoped to see something like a solar sailing race. There is a nice story by A.C.Clarke called "The Wind From the Sun". It was published in 1964! So when can I get my solar sailing yacht?
There is another nice story probably also by him where he describes runners taking part in some kind of space olympics. It was essentially a race to get the lightest space suit, which was finally genetically optimized away. I just can't remember what the name was.
Indeed they not only published articles about the terrorist=engineer meme but also about the fact that US engineers aren't involved in the political process as much as their international counterparts.
In this article they also give a good example of political involvement in the form of a Chinese engineer who worked as a spy for china in the US.
I'm not sure what they want to say with that. Do they want to go mainstream by pissing off all the engineers. There are already a number of Timeses swimming there.
Do they honestly want to encourage US engineers to play a bigger role in society with that kind of reporting?
Well I can talk to the girls at the archery club about bare shafts without them wondering what I'm talking about. Also the soccer players I was referring to are men and they don't wonder about this too much, especially since it doesn't sound as naughty in my native language (I'm having second thoughts about this though).
But this is a perfectly good joke so lets dwell on this a bit longer. I'm also continuing to totally ignore your potential sarcasm.
A direct answer would be that I'm shy and that I never meant the naughty things I said. (I would actually blush at your joke!). This might put off the girls who didn't slap me in the face when mentioning bare shafts though. If not it would still lead nowhere.
More importantly how do I get from briefly mentioning bare shafts quite innocently to say start hanging out with her more often (If I was goal oriented I would ask how to get into bed with her but lets stay reasonable). This combined with the aforementioned shyness is really a knowledge gap that is hard to overcome. Actually now that I'm thinking about this it looks easier, you just try to not get her sleepy and don't forget to exchange phone numbers, you don't have to achieve great things in one day. Maybe I should do that more often. But then there is that not letting her fall asleep part again - argh!
Also there is that problem of giving her my phone number. I don't want to get rejected outright so I would just give her mine and hope she calls back. This might look like I'm only barely interested in her though. What is the proper way of doing that? Have you developed some protocol, maybe an rfc?
That being passionate about what you do/CS part enables you to bore people to sleep/death within seconds.
I even picked a hobby like archery to talk about sports as passionately as the soccer fans and to be able to talk about something else than CS/EE. (Archery is also what I always wanted to do, at least as a hobby) No chance, the people at my club told me that archery is difficult, so difficult in fact that when god brought people archery he/she/it found that not all were able to understand it and so he/she/it invented soccer. Great! So I tried it slowly starting with the archers paradox to move to tuning your archer/bow/arrow system with the bare shaft method. The soccer guys quickly switched the topic to the riots at the latest game and to where to get the money for the new stadium from.
On the whole I would agree with you though. Fortunately this dumb Slashdot meme CS->Slashdot->Celibacy prevents reproduction and the world will be safe.
I like your attitude towards reading Knuth. I would like to discuss the nature of the drink though. Could I have a cat instead of the dog? The moor you can get away with even though I almost had to accuse you of racism. Walking across the moor and back could help solve some of those exercises too, even without access to a computer, maybe the dog would be a better companion there. You could even talk to it and you might get more attention too.
This seems to be a somehow Victorian attitude to computing - some things are just timeless.
I find this totally interesting even though it seems like C++ has been stretched beyond its limits. I think this is a good example for the complexity you complain about. People are producing useful code and even libraries based on obscure features of the compiler which the inventors never thought about. If you need compile time functionality to support programmable code generation you would expect some more explicit language features to be available for this task.
Also I always feel that I must learn about these advanced template mechanisms I have no clue about, to really understand C++. Then I notice that the rest of the world thinks that C++ is outdated and Java or something else sluggish is the language of the future. You can't write high performance code in Java (digital signal processing, image processing, real time stuff,...) however, so I will continue with C/C++. The DSP and uC environments also never support Java and rarely will they have a good C++ compiler. So I feel a bit left behind. Especially since I don't know what the next best high performance programming language will be.
You do more than that though, you teach yourself to perform certain actions by controlling your brainwaves. Who knows what system you are going to upset with this.
I say this because I used to play around with SIRDS (single image random dot stereograms) a lot up to the point where I could slip easily into the stereo mode and out. When I got that far I occasionally would wake up in the morning and my eyes wouldn't focus right when watching the ceiling. It still happens during the day that when I watch highly repetitive patterns I slip into stereo mode which takes some effort to get out off.
This is nothing serious but it should remind us that some things weren't planned for by evolution.
I just bought a CR31 (no not the pink one) and there it is selectable whether you want the Office trial and some other stuff or not. Also Vista home premium has this wonderful feature build in which allows you to shrink the Vista partition size so you can make space for Ubuntu. I wonder whether Microsoft had to get beaten up by someone to make this happen.
I have to say that I bought it in Europe maybe they do things different here. I find it interesting that Sony lets this kind of thing happen on its upscale laptops though (the TZs seem to be expensive).
Also I haven't used Vista since shrinking its partition so who knows what else lurks there.
I suspect the author of the article just wanted to make all current efforts to have a manned mission to mars look bad so people could later push for something nuclear. There are even more sane nuclear means of propulsion than Orion out there. Not that I would say it couldn't work, but having nuclear explosions happen under your behind while still on planet earth is just plain naughty from an environmental point of view.
It has been argued though that it wasn't as much of an improvement over the chemical engines it was meant to replace (J-2). This was in the sixties however and who knows where we could be now without all the naysayers.
Wiki seems to have covered sorting algorithms quite well, this is definitely some good starting point.
The development of the intro sort algorithm seems to be human driven. This questions the statement though that there hasn't been any progress on quicksort in 40 years. The greatest speed this particular algorithm can be executed at seems to be bounded at O(nlog(n)) though.
The Wiki entry about general sorting algorithms states:
"The following table describes sorting algorithms that are not comparison sorts. As such, they are not limited by a O(n log n) lower bound."
No Quicksort like algorithm should be able to exceed that bound. Somehow I would like to see a proof of that now.
You might want to switch the work place pcs off occasionally and then you don't have any access to the data. If you want to have
people work over the weekend you must switch all the machines on.
This is a more energy inefficient solution than having a large file server and Flash drives in your work PC for instance.

The logical outcome of this will be the 1280x1 display showing Morse code.
This is when ed will make sense again, hey even edlin.
If you use the diagonal you can get even a 1500x1 display.
I challenge you guys to build an olph like this.
Damn, nowadays you could fit the thing into a slide rule.
You only need one key - the "any key"!
Then the line noise languages will make sense to you.

Good to know. It might easily be possible that I became aware of this focusing error only because SIRDS caused some similar condition.
Yeah that is what it looks like on the surface.
