Q. 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.
