Trivial it ain't! More on Quicktime and IE6
by Rzepa, Henry 26 Jun '02

26 Jun '02

This is the official solution for allow plugins (in this case Quicktime) to again be played on MS IE 5.5 SP2 and IE6 XP. One presumes a similar solution will be required for Chime and other Chemical plugins. The example below suggests that an ActiveX control is downloaded from the Internet. I presume a stand alone solution suitable for eg CDROMs will also materialise. Note how the onus is on the content developer to CHANGE their HTML page to make it work. I wonder how many will.

Instead, >the browser replaces it with a "broken plug-in icon" and attempts to >assist the user in obtaining the required software. An unfortunate >side effect of this approach is that the user is directed away from >your site and is distracted by the installation process. > >THE ISSUE >Until recently, the plug-in installed as part of QuickTime worked >for both Netscape browsers and Microsoft Internet Explorer on both >Windows and Mac OS. Now Windows users who try to play a QuickTime >movie in Internet Explorer version 5.5 SP2 or later will encounter >the "broken plug-in icon" until they install the new QuickTime >ActiveX control from Apple in addition to the QuickTime plug-in. >Users of other browsers on either Windows or Mac OS are >unaffected--they can continue to use the plug-in installed with >QuickTime and do not need to get the new QuickTime ActiveX control. > >Once users have the new ActiveX control installed, they are also >unaffected; they can also view existing pages. > >THE SOLUTION >When authoring web pages, you can easily prevent this problem by >authoring your HTML to check that the required ActiveX control is >installed wherever you have QuickTime content embedded. This HTML >change will result in web pages compatible with Netscape and >Internet Explorer browsers on both Mac and Windows systems (see >below for more information). > >The required code consists of an HTML OBJECT element with an >enclosed EMBED element as in the following example: > ><OBJECT CLASSID="clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" >width="160" height="144" >CODEBASE="http://www.apple.com/qtactivex/qtplugin.cab"> ><param name="src" value="sample.mov"> ><param name="autoplay" value="true"> ><param name="controller" value="false"> ><embed src="sample.mov" width="160" height="144" autoplay="true" >CONTROLLER="false" >PLUGINSPAGE="http://www.apple.com/quicktime/download/"></EMBED> ></OBJECT> > >CLASSID must always equal: >clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B >CODEBASE must always equal: >http://www.apple.com/qtactivex/qtplugin.cab >PLUGINSPAGE must always equal: >http://www.apple.com/quicktime/download/ > >The other attributes should be customized to your web page. You need >to substitute "sample.mov" (in both SRC attribute elements) with the >URL of the actual movie to be played. You should also change the >HEIGHT and WIDTH parameters to match the height and width of the >movie (in pixels). > >If you already have EMBED elements for the QuickTime plug-in on the >relevant pages, you need to enclose each of them in an OBJECT >element with CLASSID and CODEBASE parameter values as shown above >and with SRC and other parameter values to match those in your >existing EMBED element. The OBJECT element can use any EMBED >attributes QuickTime understands. Visit >http://www.apple.com/quicktime/authoring/embed.html for more >information. > >For existing web pages, it may be sufficient to add such an OBJECT >element to the "front door" page of your site. Once the OBJECT >element on the "front door" page has caused the user to install the >ActiveX control, all subsequent pages with the original EMBED >elements will work properly. In cases where you cannot be certain >that the "front door" page is always visited, then all your pages >should be revised to use these OBJECT elements. > >HOW IT WORKS >The OBJECT element is used by Internet Explorer on Windows >9x/NT/2000/XP platforms and by other browsers that support the >QuickTime ActiveX control. The enclosed EMBED element is used by >Netscape browsers, Internet Explorer for the Mac, and other browsers >that support the "Netscape style" QuickTime plug-in. Browsers that >understand the OBJECT element ignore the EMBED element; those that >don't understand the OBJECT element use the EMBED element. > >Within the OBJECT element, the CLASSID parameter uniquely identifies >which ActiveX control to use. A CLASSID parameter with the value >"clsid:02BF25D5-8C17-4B23-BC80-D3488ABDDC6B" tells Internet Explorer >to use the QuickTime ActiveX control. (You must use exactly this >value; it is the only value that identifies the QuickTime ActiveX >control). If the user does not already have the ActiveX control >installed on his or her system, the CODEBASE parameter tells the >browser where to find it for downloading. Internet Explorer will >automatically offer to download and install the ActiveX control for >the user, after which the movie can be played without restarting the >browser, or, if QuickTime is not already installed, will prompt the >user to download and install QuickTime. You must always use >"http://www.apple.com/qtactivex/qtplugin.cab" for the CODEBASE URL. >This URL will always have the latest version of the QuickTime >ActiveX control. >Because a browser will use either the OBJECT element or the EMBED >element, but not both, most of the element attributes must be >included in each. Note that in the example above the EMBED element >has autoplay="true" and the OBJECT element has <param >name="autoplay" value="true">, so the movie will begin to play >automatically whether it is loaded with the QuickTime ActiveX >control or the QuickTime plug-in. The only attributes that should >not be duplicated are CLASSID, CODEBASE, and PLUGINSPAGE. CLASSID >and CODEBASE are specific to the OBJECT element. PLUGINSPAGE is >specific to the EMBED element. > >Although Windows Internet Explorer 5.5 SP2 and 6.0 will no longer >use the QuickTime plug-in, once the QuickTime ActiveX control has >been installed on a user's system, these versions of Internet >Explorer will use the installed ActiveX control to satisfy a >properly coded EMBED element. > >ADDITIONAL READING > >For more information on the OBJECT element, see: > * The W3C Web site at > http://www.w3.org/TR/REC-html40/struct/objects.html#edef-OBJECT > >For more information on HTML in general, see: > * HTML & XHTML: The Definitive Guide 4th Edition, > by Chuck Musciano & Bill Kennedy, published by O'Reilly. > * Dynamic HTML: The Definitive Reference, by Danny Goodman, > published by O'Reilly. > >For more information about QuickTime on Web sites, see: >QuickTime for the Web, published by Morgan Kaufmann Publishers. ><http://developer.apple.com/techpubs/quicktime/qtdevdocs/QT4WebPage/QT4WebBo…. >htm> > >For more information on Internet development, see: >http://developer.apple.com/internet/ > >Disclaimer: >IMPORTANT: This Apple software is supplied to you by Apple >Computer, Inc.

Digital archive seminar
by Wendy Warr 27 Nov '01

27 Nov '01

Seminar on Digital Preservation of the record of Science state of the art Paris, France, February 14-15 2002 ICSTI, the International Council for Scientific and Technical Information, has been encouraging discussion, debate and actions on ensuring that the record of Science continues to preserved. With the progressive movement towards digital production and distribution of scientific information there is a risk that the record represented by this material will be lost. Although many of the parties concerned with digital production and distribution have taken measures to preserve the material the effort is diffused and overall co-ordination may be necessary. .... Many other bodies in the Science community, such as CODATA, IUPAP, ICSU, interests from the international standards arena, those concerned with the creation of open archives as well as the scientific publishing community both the traditional and the newer actors, are all involved in one sense or another with preservation. In addition the library community and the representatives of the history of science community are intimately concerned. While, as noted, many activities and initiatives are under way and research programmes are in progress, the cost of digital preservation can be significant and the need to avoid duplication of effort is paramount. The need for a federal approach to both the preservation process and access to the archives has been suggested; this requires co-ordination. ... ... The topics to be discussed will be of interest to: · authors and publishers of scientific information, in particular developers of newer digital methods; · those concerned with the short and long term storage and distribution of this material, librarians and archivists; · developers of computer systems for digital archiving; · those involved in the creation of national and international standards, as well as subject or data-type oriented codes of practise; · national and international representatives from the Science community, specifically the professional and other bodies with interests in science subjects; · representatives of the scientific data community. The meeting will be held at the premises of UNESCO, with the kind permission of the Assistant Director General for Science. There is no fee for attendance but neither UNESCO nor ICSTI is in a position to offer support for travel or accommodation.

Summary: Monitors command in rasmol/chime
by Bachrach, Steven 13 Nov '01

13 Nov '01

Hens Borkent sent me a note informing me that the Monitors command is actually a rasmol script and he pointed me to the rasmol manual page. Here is the information on this command: ************************ Monitor Syntax: monitor <number> <number> monitor {<boolean>} The RasMol 'monitor' command allows the display of distance monitors. A distance monitor is a dashed (dotted) line between an arbitrary pair of atoms, optionally labelled by the distance between them. The RasMol command 'monitor <number> <number>' adds such a distance monitor between the two atoms specified by the atom serial numbers given as parameters Distance monitors are turned off with the command 'monitors off'. By default, monitors display the distance between its two end points as a label at the centre of the monitor. These distance labels may be turned off with the command 'set monitors off', and re-enabled with the command 'set monitors on'. Like most other representations, the colour of a monitor is taken from the colour of its end points unless specified by the 'colour monitors' command. Distance monitors may also be added to a molecule interactively with the mouse, using the 'set picking monitor' command. Clicking on an atom results in its being identified on the rasmol command line. In addition every atom picked increments a modulo counter such that, in monitor mode, every second atom displays the distance between this atom and the previous one. The shift key may be used to form distance monitors between a fixed atom and several consecutive positions. A distance monitor may also be removed (toggled) by selecting the appropriate pair of atom end points a second time. ******************** It would be a nice feature if rasmol/chime could also display angles and dihedral/torsional angles. Thanks to Hens for the definitive answer.

RE: Molecule-of-the-month: Model for Sharpless Expoxidation
by Bachrach, Steven 12 Nov '01

12 Nov '01

This is a nicely done page. I noticed an interesting trick (near the bottom of the page) of displaying a bond distance within chime. The key seems to be the "monitor" keywork within the embed command. There is no mention of this command in the MDL chime pages. Can anyone shed some light onto its use - it looks pretty straightforward but I would like more complete info.

Scientific Websites being hijacked by pornographic websites?
by Lachlan Cranswick 09 Nov '01

09 Nov '01

Hi, As pointed out a while back - the scientifically very useful Webmolecules website was hijacked to become a porn site due to non payment of domain registration) http://www.webmolecules.com/ (does anyone know if they have a new address?) Another addition to the pornography domain that was recently pointed out to me was: Scientific American and Nature Science and Technology Jobs http://www.scitechjobs.com ---------- My main query - does anyone know of the software that these porn people are using to find possible scientific sites to hijack - when domain registration is about to expire - then make a payment for it. The implication is they are able to analyse the significance of a scientific website (a colleague has suggested they use how many other sites link to it) - find out when the domain expires - then place a order (automatically via credit card?) to obtain it a few seconds(?) after domain registration has officially expired? Am mainly interested in seeing if this domain expirey software can be used to warn domain owners prior to their domains expiring. Thanks in advance, Lachlan. PS: Are there any "academic" resources showing how effective/profit making these hijackings might be to their new owners? E.g., what percentage of people who click through expecting a scientific site keep within the site. ----------------------- Lachlan M. D.
