Can someone use this idea for cameras ? Please pass along and maybe it will evolve into something worthwhile !?

Mr. J

Dear Reader,

I offer these ideas for your consideration. First a few comments.
In the 1980âs a type of computer program, known as an expert system, was developed to diagnose Meningitis after reviewing the symptoms of possible candidate patients. It was more effective than the doctors it was tested against ! It is, I think, reasonable to assume that many other such programs could and should be developed and made widely available to the public. This would go a long way in reducing health care cost and move us forward technologically speaking, as a species. Now to, how this relates to camera improvements.

First: It is a fact that many human diseases reveal themselves in human fingernails, toenails, and in the eye. I am suggesting that a digital camera, loaded with a well written program, probably a combination of expert system and neural network could be used to diagnose potential disease conditions. Simply, place your hand or other such appendage on a controlled surface, take a picture and analyze same. I am aware that this concept is very general but I offer it to you with the hope that you will give it fair consideration.
If successful this could open up exciting new markets for camera makers.

Second: I would like to see a camera that has a program that will determine the area of surface by simple taking a picture of it. I think this should be fairly straight forward if you were to use Pickâs formula for determining area.

Third: I would like to see a digital camera add a long exposure feature to itsâ list of features. Once again I think this should be doable by creating a program that tells the camera to take pictures at intervals and âoverlaysâ each picture, thereby capturing more light for each picture pixel. Of course, a motorized tripod could be used to capture astronomical footage. This technique should increase still picture quality by orders of magnitude !

Lastly: The Intel corporation recently announced an optical device that will be available soon that will be fast enough, I have read, to download a high definition movie in on second ! This will of course make USB obsolete. It would seem that one could use this tool to connect a camera to other devices such as a microscope, telescope, or any other âopticalâ reader and get excellent video and extreme data analysis. I hope to soon see this available to the general public.

I have posted these thoughts on the web. I hope these memes evolve and inspire others to create.

Thank you,

Mr. J
Thanks for your input Joe.

On item 1, please realize that many corporations have a vested interest NOT to create such a program, whereas, camera makers are in need of ideas that will allow them to compete with ever better cell phone cameras.

On item 2, The area idea was meant to be a quick fix to problems like , finding the area of a wall you might want to wall paper or paint. It would only be used for "good enough approximations.

On item 3, I was thinking more about the possibility of using the camera via long exposure to act as a substitute telescope. Each image captured would bring new light to the lens. A program would add this photon info, by laying each image on TOP of the prior image. The internal program could keep track of new information being picked up thereby allowing a simple camera to view deep sky objects, and vivid still photos.

If no one else has input I will give you the best answer. I just wanted to post these ideas somewhere, in the hopes that by creating a mem

Answer
1 - interesting idea - however i think it would make more sense to create some computer software and then tether it to an off the shelf camera - reducing costs over all.

2 - To determine the surface area, you would have to have a 3d model of surface, because otherwise it would not be able to take into consideration and bumps or groves, as these would just appear as a flat surface. i believe that there are laser scanners that can already do this. I think they use them to scan in the 3d sculptures that are created to create animations such as the ones produced by pixar.

3 - There is a product that does it, and infact you can do it yourself, if you take hundred of pictured of a scene from the same point, load them into photoshop, and merge them, it will create a huge image that is all of yours stitched together to make one. Google Gigapixel photo.

4 - Light Peak - the technology you are referring to most probably will make usb obsolete. Telescopes are already available with mounts that allow you to place an SLR on the back, and use it as a huge lens. And video microscopes are available, with electron microscopes being able to produce very detailed and highly magnified images. The data transfer speed is not the issue here, rather the resolution of the cameras.

Anyway, some interesting ideas.

Can i play WOW on dell studio 15?

loic hamil

Right now dell has a pretty good coupon for this laptop so if i do buy it it has to be by april 30. The problem with waiting and seeing if something else comes out is that i need a laptop this summer for some summer courses and my desktop is on its death bed right now. I can get a way cheaper laptop but i am willing to pay the extra hundreds just to play wow.

So how well will this laptop work with wrath of the lich king? i know the graphics card is crap but its the best that they will do...

WoW will run on your system just fine, as the system requirements state the following:
* Windows Vista or Windows XP
* Intel Pentium 4 or AMD Athlon XP 1500+ 1300 MHz
* 512 MB or more of RAM (1 GB for Vista Users)
* 32 MB 3D video card with Hardware T&L or better
* 15 GB free HD space
* 4Ã CD-ROM drive
* Broadband Internet connection
so, since your machine is a 2.4 Ghz dual core with 4GBs of main memory, and a 250GB hard drive, it will run pretty well, thought the graphics card may limit the game somewhat

What do you imagine the technology to be like in the future?

Soccerdang

future being, i don't know, 50, 100, 150 years from now...

Answer
Here are my favourite techno wishes:

-- A high definition 3D television

-- A talking computer but not with a robotic voice. I have worked with a program that is excellent but it is very expensive.

-- A computer that understands human speech like "open a new tab", or "close the browser", but flawlessly.

-- An engine that allows a rocket to go to Mars in 2 months (hard)

-- A medical scanner like in Star Trek (a tricorder).

-- A microchip inserted under the skin that understand limited commands just by thinking about it, like "Unlock the door", "Start the car"

-- A machine that produce high volume of fresh water from sea water.

And I am leaving aside all the medical discoveries.

What is Illusion of Depth??????!!!!!!!!?

3d scanner definition image

poopstains

i just need the definition!!!!!!

Answer
Stereopsis (from stereo meaning solidity, and opsis meaning vision or sight) is the process in visual perception leading to perception of stereoscopic depth. In turn, stereoscopic depth is the sensation of depth that emerges from the fusion of the two slightly different projections of the world on the two retinas. The difference between the two eyes' images, which is a result of the eyes' horizontal separation, is usually referred to as binocular disparity or retinal disparity. The fact that this binocular disparity is interpreted by the brain as depth was first discovered by Charles Wheatstone, a British scientist, and described by him in a classic paper[1] published in 1838: â⦠the mind perceives an object of three-dimensions by means of the two dissimilar pictures projected by it on the two retinæâ¦â, (Wheatstone, 1838). To prove his ideas, Wheatstone invented a simple device which he dubbed a stereoscope. Using his newly invented stereoscope Wheatstone was able to convincingly show that a vivid sense of depth emerges from two completely flat pictures depicting two different projections of the same scene.

or

Stereoscopy, stereoscopic imaging or 3-D (three-dimensional) imaging is any technique capable of recording three-dimensional visual information or creating the illusion of depth in an image. The illusion of depth in a photograph, movie, or other two-dimensional image is created by presenting a slightly different image to each eye. Many 3D displays use this method to convey images. It was first invented by Sir Charles Wheatstone in 1840.[1] Stereoscopy is used in photogrammetry and also for entertainment through the production of stereograms. Stereoscopy is useful in viewing images rendered from large multi-dimensional data sets such as are produced by experimental data. Modern industrial three dimensional photography may use 3D scanners to detect and record 3 dimensional information. The three-dimensional depth information can be reconstructed from two images using a computer by corresponding the pixels in the left and right images. Solving the Correspondence problem in the field of Computer Vision aims to create meaningful depth information from two images.

Traditional stereoscopic photography consists of creating a 3-D illusion starting from a pair of 2-D images. The easiest way to create depth perception in the brain is to provide the eyes of the viewer with two different images, representing two perspectives of the same object, with a minor deviation similar to the perspectives that both eyes naturally receive in binocular vision. If eyestrain and distortion are to be avoided, each of the two 2-D images preferably should be presented to each eye of the viewer so that any object at infinite distance seen by the viewer should be perceived by that eye while it is oriented straight ahead, the viewer's eyes being neither crossed nor diverging. When the picture contains no object at infinite distance, such as a horizon or a cloud, the pictures should be spaced correspondingly closer together.

My computer keeps freezing?

sirhouse

My computer freezes a lot to the point where its become "useless". I'll list the history of what happened to it and if anyone has a fix to it I'm literally going to explode out of happiness.

I got my first blue screen playing a 3D game called minecraft, all I had to do was restart my computer and it worked again. This kept happening but not to the point where it was annoying, it rarely happened.

But I kept playing games and it got to the point where I would get a blue screen after a few minutes every time I played any game or video.

I asked a question on here a while ago and I got some help that told me it was the graphics card/driver. I uninstalled the graphics driver and reinstalled it, but the problems continued.

I thought it had to be an overheating problem so I removed the back case of my laptop. But in fact this made it much worse and I thought it was because now my RAM sticks weren't seated securely and they were moving around causing it to crash much more commonly. So I took one out I couldn't find the other one but this didn't change anything at all except now it crashes even when I'm not doing anything video related like surfing the web.

Anyways thats where I'm at now. I think its a problem with the hardware because it kept getting worse over time, but I don't know what parts not working. Thanks for ANY advice/pointers!

Answer
What Operating System your using?

Suggest running the Memory Diagnostics Tool from Microsoft:
http://windows.microsoft.com/en-nz/windows7/diagnosing-memory-problems-on-your-computer

If one or more memory sticks is corrupted at a point, then your find that your computer will randomly crash (when it has reached and tries to use that address). So, this could happen at any time - boot time, during any application/game, etc. If this is your issue, then carefully remove all memory sticks (after removing static from your body by grounding yourself - for example: touching a piece of metal area on the computer) except for one and retest each individually... place back any good ones and replace the damaged one(s).

Next scan your computer hard drive(s) for errors, go under "My Computer" -> Right click on each Local Disk (one at a time) -> Properties -> Tools (tab) -> Erroring Checking -> Check Now. Select automatically fix file system errors and also check for bad sectors option. If the drive is in use, it might ask to check on next boot up instead (say okay and restart).

Next scan your computer for viruses, spyware and trojans. If you already have an virus scanner, then ensure it is up-to-date as well as Windows, a good firewall and other applications you use regularly. Most virus scanner are utter rubbish, I recommend total application control rather than virus definition only scanners. This means something which gives or denies each application/game access to various areas of your system (including itself) with a strong firewall to prevent any network access, such as Kaspersky Internet Security.

You can check with some free tools, such as: http://www.kaspersky.com/virus-scanner

Also, check for spyware using a free manual running application (which doesn't conflict with your virus scanner) such as Lava Soft Ad-Aware: http://www.lavasoft.com/products/ad_aware_free.php or Spybot: http://www.safer-networking.org/dl/

Next clean out any startup background applications and/or services you don't need. This is more advance, only remove what you know is and don't want. You can use Start -> Run -> type "MsConfig.exe" and press enter, then look under the Startup tab, also more carefully under the Services tab (Leave it alone or Google search the name of each if unsure what it is/does).

Linux live cd with good antivirus scan?

Milkduds

I was on a website, youtube and cgtextures.com and I was redirected to a fake rouge antivirus where it tells me my computer has x amount of threats blah blah blah. I quickly alt F4d out and scanned my computer. Nothing came up so I hope I didnt get anything. First off can someone explain to me a little about this fake antivirus scareware. I dont believe I have a computer with trojans malware or viruses becuase its only 2 months old and dedicated to 3D work. It runs windows7 64bit. This is why I am thinking it was definately a redirect.

I already have a linux live CD, but is there a good linux live CD that has a good virus scanner. That way incase I ever did get a virus I could remove it without reinstalling the OS and all my software which would take atleast a day.
Adding to the question. It doesnt seem like either of these websites would redirect to a virus scam site. Is it possible that one of the adds on the sites slipped through Googles radar and was actuall bad? I am mostly concerned as to why this happened.

Answer
Use a clean Windows or Mac computer and download this SystemRescueCD ISO

http://www.sysresccd.org/Main_Page


For Windows use the free ImgBurn to burn the ISO to a cd

(on a Mac use Apple's Disk Utility in the Applications > Utilities folder)

Research online what the BIO's boot key to hold to enter the BIO's for the infected computer.

Make sure the infected computer has a WIRED internet connection to the router with a Ethernet cable.

Insert the SystemRestorecd into the infected computer, boot and enter the BIO's, set the cd as the first boot option. You'll now boot into SystemRescue, select the Graphical interface.

You'll see a Terminal window, type the two following commands and press enter after each one

clamd

freshclam

clamd is the virus scanner, freshclam updates the definitions via the internet online

Next there is a icon on the bottom, mouse over it, click it and it should open to be Gparted.

Once Gparted window is open, look on the right popup menu for the list of drives, you want the FAT or NTSF formatted one that Windows uses, check the size too. It should be obvious. Now get the name of the drive Linux uses to identify it either sda1 or sda2 usually.

Once you got that, close Gparted Window.

Now back to terminal type the one of the following depending if it's sda1 or sda2 (or sda3 or sda4 etc for the windows drive)

ntfs-3g /dev/sda1 /mnt/windows

ntfs-3g /dev/sda2 /mnt/windows

ntfs-3g /dev/sda3 /mnt/windows

ntfs-3g /dev/sda4 /mnt/windows

next type:

clamscan -vri /mnt/windows

and let her rip for a few hours, the monitor will likely sleep, you can use the mouse to wake it up.

come back and you'll have a status report and can quarantine infected files. Take the names and locations down to do research. If there are a lot, then you need to grab your files, you'll need to factory restore Windows.

Either boot into safe mode on windows and attempt to transfer files or better yet

On a safe machine, burn a ISO of Ubuntu downloaded from this page (easiest and direct way)

http://www.linuxliveusb.com/en/help/guide/step2

Use the ImgBurn or OS X Disk Utility and follow the same boot methods on the infected computer like above. You don't need a internet connection, but you do need a blank FAT formatted external USB drive (Windows or OS X Disk Utility can format that)

Hook up the external to the infected computer, boot off the Ubuntu cd and "try" Ubuntu, once the desktop appears, simply select the Places menu > Computer and select the Windows drive, navigate to your files and copy them to the external drive window via drag and drop methods.

It's also possible from the terminal on SystemRestoreCd to copy files to a external drive as well, but this takes some knowledge, I used the Ubuntu GUI method as the easiest.

The advantage of a Linux Live cd scan is that Windows doesn't run, thus the malware doesn't run and the cd is write protected, a different OS and the more secure Linux as well. Malware has little chance to lie to you this way like it does when Windows is running. Also Linux scans the whole drive, instead of a malware controlled Windows only scanning parts it wants you to scan.

Once you get a clean Windows computer again, you should first have your external drive virus scanned and cleaned on a Linux or OS X machine before hooking back to your new clean Windows, new malware comes out all the time so definitions need to be updated and a rescan done.

import java.util.Scanner;

public class Average {

public static void main(String[] args) {

Scanner input = new Scanner (System.in);

int average = 0;
int number = 0;

System.out.println("Please input 3 numbers");

number = input.nextInt();
number = number + input.nextInt();
number = number + input.nextInt();

average = number/3;
System.out.println("Your average is " + average);
}
}

When it calculates the average, it doesn't calculate into the decimal values. How do I get it to do that?

Answer
Declaring average as a float or double is not the answer. It is just part of the answer.

The sum
number / 3
is an integer divided by an integer. This will result always in an integer.
Changing one or both of the numbers to the type of the receiving variable will give you the result that you are looking for.
To make a variable a different type you can change the definition or you can use casting.
To change a constant to a different type you use a type suffix.
3.0 is a double, being the default option
3D, 3d, 3.0D, 3.0d are all double because of the d suffix.
3F, 3f, 3.0F, 3.0f are all float because of the f suffix.

Have fun.

Can someone use this idea for cameras ? Please pass along and maybe it will evolve into something worthwhile !?

Mr. J

Dear Reader,

I offer these ideas for your consideration. First a few comments.
In the 1980âs a type of computer program, known as an expert system, was developed to diagnose Meningitis after reviewing the symptoms of possible candidate patients. It was more effective than the doctors it was tested against ! It is, I think, reasonable to assume that many other such programs could and should be developed and made widely available to the public. This would go a long way in reducing health care cost and move us forward technologically speaking, as a species. Now to, how this relates to camera improvements.

First: It is a fact that many human diseases reveal themselves in human fingernails, toenails, and in the eye. I am suggesting that a digital camera, loaded with a well written program, probably a combination of expert system and neural network could be used to diagnose potential disease conditions. Simply, place your hand or other such appendage on a controlled surface, take a picture and analyze same. I am aware that this concept is very general but I offer it to you with the hope that you will give it fair consideration.
If successful this could open up exciting new markets for camera makers.

Second: I would like to see a camera that has a program that will determine the area of surface by simple taking a picture of it. I think this should be fairly straight forward if you were to use Pickâs formula for determining area.

Third: I would like to see a digital camera add a long exposure feature to itsâ list of features. Once again I think this should be doable by creating a program that tells the camera to take pictures at intervals and âoverlaysâ each picture, thereby capturing more light for each picture pixel. Of course, a motorized tripod could be used to capture astronomical footage. This technique should increase still picture quality by orders of magnitude !

Lastly: The Intel corporation recently announced an optical device that will be available soon that will be fast enough, I have read, to download a high definition movie in on second ! This will of course make USB obsolete. It would seem that one could use this tool to connect a camera to other devices such as a microscope, telescope, or any other âopticalâ reader and get excellent video and extreme data analysis. I hope to soon see this available to the general public.

I have posted these thoughts on the web. I hope these memes evolve and inspire others to create.

Thank you,

Mr. J
Thanks for your input Joe.

On item 1, please realize that many corporations have a vested interest NOT to create such a program, whereas, camera makers are in need of ideas that will allow them to compete with ever better cell phone cameras.

On item 2, The area idea was meant to be a quick fix to problems like , finding the area of a wall you might want to wall paper or paint. It would only be used for "good enough approximations.

On item 3, I was thinking more about the possibility of using the camera via long exposure to act as a substitute telescope. Each image captured would bring new light to the lens. A program would add this photon info, by laying each image on TOP of the prior image. The internal program could keep track of new information being picked up thereby allowing a simple camera to view deep sky objects, and vivid still photos.

If no one else has input I will give you the best answer. I just wanted to post these ideas somewhere, in the hopes that by creating a mem

Answer
1 - interesting idea - however i think it would make more sense to create some computer software and then tether it to an off the shelf camera - reducing costs over all.

2 - To determine the surface area, you would have to have a 3d model of surface, because otherwise it would not be able to take into consideration and bumps or groves, as these would just appear as a flat surface. i believe that there are laser scanners that can already do this. I think they use them to scan in the 3d sculptures that are created to create animations such as the ones produced by pixar.

3 - There is a product that does it, and infact you can do it yourself, if you take hundred of pictured of a scene from the same point, load them into photoshop, and merge them, it will create a huge image that is all of yours stitched together to make one. Google Gigapixel photo.

4 - Light Peak - the technology you are referring to most probably will make usb obsolete. Telescopes are already available with mounts that allow you to place an SLR on the back, and use it as a huge lens. And video microscopes are available, with electron microscopes being able to produce very detailed and highly magnified images. The data transfer speed is not the issue here, rather the resolution of the cameras.

Anyway, some interesting ideas.

Linux live cd with good antivirus scan?

Milkduds

I was on a website, youtube and cgtextures.com and I was redirected to a fake rouge antivirus where it tells me my computer has x amount of threats blah blah blah. I quickly alt F4d out and scanned my computer. Nothing came up so I hope I didnt get anything. First off can someone explain to me a little about this fake antivirus scareware. I dont believe I have a computer with trojans malware or viruses becuase its only 2 months old and dedicated to 3D work. It runs windows7 64bit. This is why I am thinking it was definately a redirect.

I already have a linux live CD, but is there a good linux live CD that has a good virus scanner. That way incase I ever did get a virus I could remove it without reinstalling the OS and all my software which would take atleast a day.
Adding to the question. It doesnt seem like either of these websites would redirect to a virus scam site. Is it possible that one of the adds on the sites slipped through Googles radar and was actuall bad? I am mostly concerned as to why this happened.

Answer
Use a clean Windows or Mac computer and download this SystemRescueCD ISO

http://www.sysresccd.org/Main_Page


For Windows use the free ImgBurn to burn the ISO to a cd

(on a Mac use Apple's Disk Utility in the Applications > Utilities folder)

Research online what the BIO's boot key to hold to enter the BIO's for the infected computer.

Make sure the infected computer has a WIRED internet connection to the router with a Ethernet cable.

Insert the SystemRestorecd into the infected computer, boot and enter the BIO's, set the cd as the first boot option. You'll now boot into SystemRescue, select the Graphical interface.

You'll see a Terminal window, type the two following commands and press enter after each one

clamd

freshclam

clamd is the virus scanner, freshclam updates the definitions via the internet online

Next there is a icon on the bottom, mouse over it, click it and it should open to be Gparted.

Once Gparted window is open, look on the right popup menu for the list of drives, you want the FAT or NTSF formatted one that Windows uses, check the size too. It should be obvious. Now get the name of the drive Linux uses to identify it either sda1 or sda2 usually.

Once you got that, close Gparted Window.

Now back to terminal type the one of the following depending if it's sda1 or sda2 (or sda3 or sda4 etc for the windows drive)

ntfs-3g /dev/sda1 /mnt/windows

ntfs-3g /dev/sda2 /mnt/windows

ntfs-3g /dev/sda3 /mnt/windows

ntfs-3g /dev/sda4 /mnt/windows

next type:

clamscan -vri /mnt/windows

and let her rip for a few hours, the monitor will likely sleep, you can use the mouse to wake it up.

come back and you'll have a status report and can quarantine infected files. Take the names and locations down to do research. If there are a lot, then you need to grab your files, you'll need to factory restore Windows.

Either boot into safe mode on windows and attempt to transfer files or better yet

On a safe machine, burn a ISO of Ubuntu downloaded from this page (easiest and direct way)

http://www.linuxliveusb.com/en/help/guide/step2

Use the ImgBurn or OS X Disk Utility and follow the same boot methods on the infected computer like above. You don't need a internet connection, but you do need a blank FAT formatted external USB drive (Windows or OS X Disk Utility can format that)

Hook up the external to the infected computer, boot off the Ubuntu cd and "try" Ubuntu, once the desktop appears, simply select the Places menu > Computer and select the Windows drive, navigate to your files and copy them to the external drive window via drag and drop methods.

It's also possible from the terminal on SystemRestoreCd to copy files to a external drive as well, but this takes some knowledge, I used the Ubuntu GUI method as the easiest.

The advantage of a Linux Live cd scan is that Windows doesn't run, thus the malware doesn't run and the cd is write protected, a different OS and the more secure Linux as well. Malware has little chance to lie to you this way like it does when Windows is running. Also Linux scans the whole drive, instead of a malware controlled Windows only scanning parts it wants you to scan.

Once you get a clean Windows computer again, you should first have your external drive virus scanned and cleaned on a Linux or OS X machine before hooking back to your new clean Windows, new malware comes out all the time so definitions need to be updated and a rescan done.
