Gabriele 10-Apr-2009 [3782] | now imagine you make a phone call, and this "something you can talk to" responds, and has access to google, wolfram alpha... and qtask. |
AdrianS 10-Apr-2009 [3783] | Wow, maybe the combination of these two technologies can find a way out of the mess the financial system is in - like, "Hang the bastards that caused it!" |
Reichart 11-Apr-2009 [3784] | Very fun little movie made to show how magnetic waves might "look" (and sound). http://www.semiconductorfilms.com/root/Magnetic_Movie/Magnetic.htm |
Henrik 13-Apr-2009 [3785] | http://www.youtube.com/watch?v=0jyBiECoS3Q Cool insect bot. One can think about why it's so much easier to build insect robots than humanoid/biped robots. |
Reichart 13-Apr-2009 [3786] | Well said. http://www.youtube.com/watch?v=0jyBiECoS3Q |
Reichart 16-Apr-2009 [3787] | Some good news ... http://www.sciencedaily.com/releases/2009/04/090414084627.htm |
[unknown: 5] 16-Apr-2009 [3788] | That is good news. |
Geomol 16-Apr-2009 [3789] | Recently I've been speculating a lot, if it's a good idea, that humans save animals. Initially it seems like a very good idea. But fact is, that more than 90% of all species at any time have become extinct at a later time. Every time a species become extinct, it makes room for other species. Now if us people start to save species, that would else become extinct, what effect will this have over a longer time-scale? |
[unknown: 5] 16-Apr-2009 [3790] | Does it matter? Isn't the universe becoming more organized? So during this evolution we should expect more organization so what harm can be done if we are apart of it. |
Reichart 16-Apr-2009 [3791] | John, I hear there was a meeting among the animals, all I can say is, there was a vote, and "we" better make plans for another planet. |
Geomol 16-Apr-2009 [3792] | Yeah, let's take to the skies! :-) |
sqlab 17-Apr-2009 [3793] | We are adapted to a certain (now existent ?) environment. If it changes maybe we will change or get extincted too. |
Maarten 17-Apr-2009 [3794] | Reichart, that is very funny. |
Geomol 18-Apr-2009 [3795] | Future now? One step closer to Minority Report. http://www.snotr.com/video/2549 |
Graham 18-Apr-2009 [3796] | Looks like the spammers have found a way to get thru gmail's filters ... finding a lot more spam now in the last few days in my inbox. |
Reichart 18-Apr-2009 [3797] | Most of my spam comes from Germany or Italy on Gmail... |
Graham 18-Apr-2009 [3798] | No Russian ladies any more? |
[unknown: 5] 19-Apr-2009 [3799] | I get it mostly from mail.ru and gmail |
Graham 19-Apr-2009 [3800] | spam or bots ? |
[unknown: 5] 19-Apr-2009 [3801] | I don't know how to tell the difference. They simply like ot register on my sites and then leave a website link in their profile. Seems they are just looking for backlinks. |
Graham 19-Apr-2009 [3802] | bots |
Oldes 19-Apr-2009 [3803x2] | Just write your forms using JS or at least don't use common login field names like USER and PASSWORD |
but if you don't hide the submit button, they will try to insert the links into any text field. | |
[unknown: 5] 19-Apr-2009 [3805x6] | I thought of a great idea to stop forum spammers and probably others. I don't know how it can be thwarted. |
I wouldn't know how to code it but it would probably require Javascript which I don't know. | |
But that might not be a good idea. Need something almost other than javascript. | |
The idea is to use Drag and Drop. | |
The drag and drop areas always change. | |
So its random generated. | |
ICarii 19-Apr-2009 [3811] | 3D hit testing is another upcoming captcha method |
[unknown: 5] 19-Apr-2009 [3812] | How does that work? I hear that cpatcha is being beaten by OCR methods. |
ICarii 19-Apr-2009 [3813] | there are various implementations from thread-the-needle / drag-and-drop / to overlay matching and rotation |
[unknown: 5] 19-Apr-2009 [3814] | My idea involves having the backend generate a random code that gets presented as a draggable item in a javascript driven page. The user must drag the code to a randoming placed box. The code i s also randoming placed. The script will generate a value based on the direction and length of the drag. This gets compared on the server end along with the code. |
ICarii 19-Apr-2009 [3815] | cant the spammer then just read the code to get the positions? |
[unknown: 5] 19-Apr-2009 [3816] | Yeah, which is why I don't think you can do it in javascript. I'm using that as an example to get an idea for the concept. |
ICarii 19-Apr-2009 [3817] | automating mouse movement and clicks from then on is relatively trivial |
[unknown: 5] 19-Apr-2009 [3818] | Yeah might not work via that route. |
ICarii 19-Apr-2009 [3819] | the trick is to possibly send location on drop - then verify serverside |
[unknown: 5] 19-Apr-2009 [3820x2] | Yeah - that should do it! |
Dunno, you still have to show the locations on the client end so they know where to drag. | |
ICarii 19-Apr-2009 [3822x2] | send an image |
eg: drag the object onto the purple rabbit - have an image with 20 or so differentr rabbits | |
[unknown: 5] 19-Apr-2009 [3824x3] | Possible. |
How about this. You display a rather large image and the user must click the very center of image (hold down button) and drag to a border speciied within the image. The image changes. | |
For example say the image is just a picture of a large ball or circle. The person clicks the center of the circle and holds down to expand to the perimeter of the circle in the image and releases and this gets interpretes as radius back to the server. | |
ICarii 19-Apr-2009 [3827] | still open to image analysis attack |
Oldes 19-Apr-2009 [3828] | Captachas are agains people, not bots. Bots are mostly very simple, especially the one which just puts links into fields. Why they would spend time on image analysis when they just can travel on another site with simple forms. fields. |
ICarii 19-Apr-2009 [3829] | they broke the gmail captcha and yahoo and hotmail by use of image analysis. |
Oldes 19-Apr-2009 [3830] | people.. not bots:) |
ICarii 19-Apr-2009 [3831] | oh - i thought they were reported to have automated it? |
