Cuil Theory

Monday, August 24th, 2009

This deserves to be preserved on the internet. Original source at: http://cuiltheory.wikidot.com/what-is-cuil-theory

Origins of Cuil Theory.

The idea was to lampoon the terrible search engine capabilities of the Cuil search engine, while providing a functionally stimulating idea about the interrelationship between tangential things.

The result was the following exchange:


HalCion: Reddit’s thumbnails have a Cuil level of effectiveness.RedDyeNumber4 Can we make that a unit of measurement?

One Cuil = One level of abstraction away from the reality of a situation.

Example: You ask me for a Hamburger.

1 Cuil: if you asked me for a hamburger, and I gave you a raccoon.

2 Cuils: If you asked me for a hamburger, but it turns out I don’t really exist. Where I was originally standing, a picture of a hamburger rests on the ground.

3 Cuils: You awake as a hamburger. You start screaming only to have special sauce fly from your lips. The world is in sepia.

4 Cuils: Why are we speaking German? A mime cries softly as he cradles a young cow. Your grandfather stares at you as the cow falls apart into patties. You look down only to see me with pickles for eyes, I am singing the song that gives birth to the universe.

5 Cuils: You ask for a hamburger, I give you a hamburger. You raise it to your lips and take a bite. Your eye twitches involuntarily. Across the street a father of three falls down the stairs. You swallow and look down at the hamburger in your hands. I give you a hamburger. You swallow and look down at the hamburger in your hands. You cannot swallow. There are children at the top of the stairs. A pickle shifts uneasily under the bun. I give you a hamburger. You look at my face, and I am pleading with you. The children are crying now. You raise the hamburger to your lips, tears stream down your face as you take a bite. I give you a hamburger. You are on your knees. You plead with me to go across the street. I hear only children’s laughter. I give you a hamburger. You are screaming as you fall down the stairs. I am your child. You cannot see anything. You take a bite of the hamburger. The concrete rushes up to meet you. You awake with a start in your own bed. Your eye twitches involuntarily. I give you a hamburger. As you kill me, I do not make a sound. I give you a hamburger.

6 Cuils: You ask me for a hamburger. My attempt to reciprocate is cut brutally short as my body experiences a sudden lack of electrons. Across a variety of hidden dimensions you are dismayed. John Lennon hands me an apple, but it slips through my fingers. I am reborn as an ocelot. You disapprove. A crack echoes through the universe in defiance of conventional physics as cosmological background noise shifts from randomness to a perfect A Flat. Children everywhere stop what they are doing and hum along in perfect pitch with the background radiation. Birds fall from the sky as the sun engulfs the earth. You hesitate momentarily before allowing yourself to assume the locus of all knowledge. Entropy crumbles as you peruse the information contained within the universe. A small library in Phoenix ceases to exist. You stumble under the weight of everythingness, Your mouth opens up to cry out, and collapses around your body before blinking you out of the spatial plane. You exist only within the fourth dimension. The fountainhead of all knowledge rolls along the ground and collides with a small dog. My head tastes sideways as spacetime is reestablished, you blink back into the corporeal world disoriented, only for me to hand you a hamburger as my body collapses under the strain of reconstitution. The universe has reasserted itself. A particular small dog is fed steak for the rest of its natural life. You die in a freak accident moments later, and you soul works at the returns desk for the Phoenix library. You disapprove. Your disapproval sends ripples through the inter-dimensional void between life and death. A small child begins to cry as he walks toward the stairway where his father stands.

Wordpress and Mac Safari does not work properly

Wednesday, August 19th, 2009

Looks like doing a copy/paste in wordpress with Apple’s Safari browser does not work properly.   Carriage returns  (or newlines) is not copied over, and also copied hyperlinks do not automatically get recognized as a hyperlink (pastes as regular text) .

Disappearing icons on mounted Windows NT Server volumes on Macs

The next four articles discuss problems of disappearing file icons.

1. Microsoft Windows NT Server 3.51, 4.0, files disappear from mounted server volumes on Macs

Files on the mounted server volume on Mac clients disappear, but are still visible on Windows clients and from the server. This is an acknowledged Microsoft bug that was fixed with Windows NT Service Pack 3 for Windows NT 4.0. In July of 1997 Microsoft created a “hotfixed” version of Sfmsrv.sys file (available by calling Microsoft technical support). Microsoft recommends rebuilding Macintosh volumes after applying the hot fix. However, Service Pack 4 fixes a variety of bugs with Windows NT 4.0, and is recommended by Microsoft.Directly below are several methods of recovering files that have disappeared.2. Microsoft Windows NT 4 Server — When server crashes, files disappear from mounted server volumes on MacsOne disappearing-icons problem that NT Service Pack 3 doesn’t fix occurs when a Windows NT 4.0 Server running Services for Macintosh crashes. After rebooting the NT server, Macintosh users may find that random files are missing from the NT volumes, though the files are visible to Windows 95 users who access the same volumes, but not the Macs, no matter what you do. Running chkdsk or any other disk management tool will not help. Consultant Greg Barry warns NOT to move the files with a Windows 95 PC, or “corruption is guaranteed.”Cause of the Problem:The AFP volume indexes are stored in RAM on the server and are used by the Services for Macintosh file server. The SFM process manages the indexes for each volume constantly and makes heavy use of RAM for this processing. These indexes are written to disk at shutdown and may be written at other un-documented times. When the server crashes, the indexes are lost and the old ones are read from disk. These indexes are responsible for the contents of the AFP volumes that the user sees. Even when SFM is stopped and started, the files do not come back.Solution:This is a known Microsoft by that was fixed in the June, 1998 hotfix called sfm-fixi.exe, which enables SFM to rebuild the indexes upon restart after a crash. This is the multiple-bug hotfix that includes fixes for 10 SFM Service Pack 3 bugs, including the Jumping icon fix.Alternate solution:Chris Pepper offers this manual approach:

I was able to clear this problem by moving the missing files into a different directory (existing or newly created; could be a subdirectory of the affected directory), and then moving them back, on the server itself. As soon as the files were moved, they showed up on the Mac; they remained visible after moving them back.

Another method of updating the index file:Jerry Lees sent in a method that he uses to prevent the problem of Mac files disappearing from NT Server. He is Running NT 4 SP 5.

I too have found this to be a problem on my network. I have not done a lot of tracing to find the source of the problem… mainly because I have found a patch to the problem that I can run periodically.Basically, I have a batch file that runs nightly and renames the files like this:ren *.jpg *.jalren *.jal *.jpgren *.htm *.jalren *.jal *.htmAnd so forth. This forces the index to be updated and rebuilt.

3. Microsoft Windows NT 4 Server — Recovering files that disappear from mounted server volumes on Macs.If you don’t yet have the sfm-fix hotfix mentioned above, Kevin van Haaren of HNTB Corporation sent us this method of recovering files that disappeared from the Macs but were still visible from Windows machines. This method does not require rebooting the NT server or Mac clients.

  1. Get all users to dismount the volume
  2. Remove the volume
  3. Apply file-level permissions on all sub-directories (from Windows Explorer) with just Administrators full-control
  4. Recreate mac volume setting the permissions as needed

Joe Clarke adds that simply recreating the Mac volumes forces a desktop rebuild with all the icons restored. Things that must be addressed after using this procedure are custom volume icon (if any) disappearance, and icon rearrangment.4. NT jumping icon hotfix created a disappearing icon bug.Microsoft says that the hotfix for the jumping icons bug (and other bugs) created a new bug on volumes with large numbers of files. With over 10,000 or so files on a volume, the SFM hotfix causes some file icons to disappear from mounted volumes on Macs. Upon rebuilding the Mac volume, the server can occasionally crash.Microsoft said that NT 4.0 Service Pack 4 fixed this new problemThis also might fix the problem:

Method 5

If the issue exists in a volume that is part of a folder (for example, D:\Public), type the following command at a command prompt:

dir > d:\public:afp_idindex

If you are rebuilding a root drive share such as C:\ or D:\, type the following command at a command prompt:

dir > d:\:afp_idindex

NOTE: This command intentionally damages the index of the Macintosh volume. After SFM is stopped and restarted, the damage forces Windows NT to rebuild the index on that volume immediately. If an “access denied” error message occurs, the volume may be in use by opened files or the folder is being shared for personal computer access. Disable all programs and file sharing to prevent this error message.

After SFM is restarted and the index is complete, an event is logged in Event Viewer. If the volume is large in size, it may take several minutes before all volumes and files are visible by the Macintosh client. Avoid stopping the SFM service at this time.
The following error will appear when you corrupt the volume index:

Cool company that makes a kiosk that creates a 3d laser engraved image of yourself in 5 minutes.

http://www.3d-etc.com/

Saw it first at the Montreal Eaton Centre two years ago.   I think it cost somewhere between $5 to $10 to create the image.   Strangely though, it doesn’t seem to have expanded much more in Canada.   Seems to have quite a few installations in the U.S. .     Not easy to find on google either…

Update:  Aug 4, 2010

The website seems to have removed all references of its installed locations.   I can only assume that they might not be focusing on the 3d kiosk any more.

However, I’ve found the parent manufacturer for this kiosk, located in a company that seems to be in China.   The company is called Heifei Cnca Laser.       http://www.cncalaser.com/  .    The only new news item is a reference to a showing in Kuala Lumpur, July 2010.

Notes on setting up a sbgrid workstation

Wednesday, August 12th, 2009

(work in progress)

Preparing a fedora 7 linux computer for stereo molecular modelling using sbgrid structure.

Install all updates  -  yum update

Get Livna rpm for fedora 7 - this will allow yum to automatically connect to the livna repositories

Assuming the installed hardware has a stereo capable nvidia card

Yum install kmod-nvidia rpm

Livna display configuration - disable all (gdm etc)

Possible problems : graphics card might not recognize monitor - esp if monitor does not transmit proper plug+play id codes, try different monitor brand if you have trouble over 800×600 .   Otherwise, must need to manually define monitor type, or modify the xorg.conf file.

If using sbgrid, copy /programs from a donor computer.

Notes:  I tried the Bad Copy Pro demo and it didn’t much of anything.   For my particular problem, I would rate this software as a fail.

http://www.restorer-ultimate.com

Notes:   The demo was able to find entire directory structures and all the file contents.   Was satisfied enough to buy the software immediately.   Highly recommend it.
