drawing lines with Chime?
by apa＠adfa.oz.au 05 Aug '96

05 Aug '96

Greetings from a far-flung ex-colony, To all Chime gurus: Is it possible to draw a series of lines on top of a displayed molecule using the Rasmol scripting capabilities of Chime? For example, I'd like a hexagon to be drawn over a six-membered Si/Al ring in a zeolite that is diplayed as a live molecule, or display the sides of a tetrahedron encompassing a SiO4 unit, when a user presses one of those little crossed form butons. I guess that an alternative is to manually construct a fake hexagon/tetrahedron residue in the chime data file and have the script highlight these dummy atoms. Any examples out there before I reinvent the wheel? BTW, where is the chime scripting documentation hidden? ---- Alan Arnold, School of Chemistry, University College (UNSW) Australian Defence Force Academy, CANBERRA ACT 2600 Australia voice:+61 6 268 8080 fax:+61 6 268 8002 e-mail: apa(a)adfa.oz.au WWW: http://apamac.ch.adfa.oz.au/apa/apa.html ----- chemweb: A list for Chemical Applications of the Internet.

MOTM
by Paul May 01 Aug '96

01 Aug '96

Hi, August's Molecule of the Month is now on-line. It's actually 2 molecules, helvetane and israelane, and has been provided by Mitchell Miller from MDL Information Systems, Ltd (the authors of Chime). The 2 molecules are hypothetical, but have really interesting shapes. The MOTM is actually on the Bristol site, and only the non-Chimed version is ready at the moment - although the Chimed version should be available any day now (as soon as our system admin people add the MIME type for .mol files to the web server config!). As always, it's available from: http://www.bris.ac.uk/Depts/Chemistry/MOTM/motm.htm Regards, ----------------------------------------------------------------------------- Dr Paul May, School of Chemistry, University of Bristol, UK tel: +44 (0)117 9287667, fax: +44 (0)117 9251295 email: paul.may(a)bris.ac.uk WWW: http://www.bris.ac.uk/Depts/Chemistry/staff/pwm.htm ----------------------------------------------------------------------------- ----- chemweb: A list for Chemical Applications of the Internet.

browser profiles over the last 7 months
by M.Winter＠Sheffield.ac.uk 01 Aug '96

01 Aug '96

For your interest I enclose percentage browser stats for the last 6 months here. There's all sorts of reasons why these numbers aren't scientific but the apparent trends are interesting anyway. You may find these numbers helpful when deciding what features to implement on your pages. Browsers vers Jan Feb Mar Apr May Jun Jul MSIE 3.9 3.6 5.8 6.4 5.2 5.7 7.3 Mosaic 3.1 3.1 2.9 3.0 2.4 2.0 1.8 NetScape 0.9 1.6 0.8 0.9 0.5 0.6 0.4 0.3 NetScape 1 7.0 4.2 3.0 2.5 2.8 2.0 1.1 NetScape 1.1 30.3 25.8 21.7 18.3 14.9 12.6 9.0 NetScape 1.2 22.7 19.1 16.9 11.8 13.4 9.8 6.7 NetScape 2 26.8 37.2 44.0 51.3 50.4 53.3 53.4 NetScape 3 0 0 0.1 2.2 6.0 11.1 17.8 All other browsers are very small. Currently, NetScape seems to register 88% of hits but some browsers which are not NetScape register as such so 88% could be too high if I've missed some that show this behaviour. Version 3 (beta) was 18% last month. Version 2 is steady at present but the proportion of version 1 users is dropping steadily. My current favourite, MS InterNet Explorer is steady but less than 8%. Nearly 80% of all hits come from [NetScape v2 or better + MSIE] and given that MSIE is at least as capable as NetScape 2, so we are fast approaching a point at which NetScape version 2 capabilities can be assumed.

(Or do I get Club points? :-) Cookies can provide a valuable service to both "user" and "provider," and should not be seen as completely evil and restraining one's freedom. We are using cookies here at Tripos for our Sybyl/Unity beta program, and I think the user will see a definite benefit. In our case, we are using the cookie file to record user name, email address, and phone number, AFTER the user has entered it once in the registration form. The cookie allows us to not have to prompt the user EVERY time they link up to the beta information site -- we get the info from the cookie file. If you do delete or edit the cookie file, then the user must again enter all of the information we require to provide them with beta assistance. Are we asking for private information in the registration? No. All of our user sites are (of course) already known to us, since they have licensed our software. The individuals are all persons who have agreed to work with us, where we receive the benefit of more field testing, and they receive the benefit of early access to a needed software product (plus get direct communication with programmers at Tripos). I can't see how anyone would seriously consider this use of "cookies" to be an invasion of privacy. All of the registrants have willingly volunteered to participate, and we are providing a mechanism that says "Hi, welcome back, no need to enter all that registration info again!"

Cookie Requests
by Rzepa, Henry 30 Jul '96

30 Jul '96

Netscape 3, under Options/Network/Protocols allows an alert to be shown if a remote server has asked to write into your "cookie" file. I encountered such a request from e.g. http://structbio.nature.com/1996-April/thesolutionstructureofhivnefre Of course, you can inspect your cookie file to see what it wrote there (if you can make sense of it), and only the originating server can subsequently make use of this information. I still find it interesting to know exactly what information is being saved in this file, and what use the remote service makes of it. Some of it is clearly useful (ie version number of the browser you use etc), some of it may prove useful in your browsing of the site (ie you have visited the config page, and there is no reason to go there again) and some may relate to e.g. the user has viewed this article 3 times previously, so let us act upon this information. I suppose its a bit like the "club" cards in supermarkets, where the supermarket knows more about your weekly shopping habits than you do (I suspect for example that supermarkets must have a pretty good idea of the level of alcoholism in the country. Should your local supermarket alert your doctor if it concludes you are over-doing it for example?) I strongly suspect that the use of "persistent client states" as they are known, is likely to increase dramatically. Perhaps many of us will not mind if the remote server is keeping a "stateful" record of our browsing. But how would visitors from the commercial side of things view this? Is it part of the "e-world", or should we be concerned. i am keeping an open mind on this at the moment! Dr Henry Rzepa, Dept.

I have been hearing about "Magic Cookies" for a while, but what follows is the best description I have seen. I am using the software Cookie Monster on all of the Macs in our lab, and on my personal computer, as I have already been getting junk mail from some of the sites I have visited. Just depends on whether you want people to know where you are going and where you have been. I have not had any problems with it so far. The URL for this information and to download the software (it is e-mail ware)is: http://www.macworld.com/software/IndexSoftware.NewUploads.html Cookie Monster 1.5.1 The following is the description posted on that page: Author: Nicolas Berloquin Needs: Netscape Navigater or Microsoft Explorer Equipment: Macintosh Fee: e-mail ware File size: 9 K The Magic Cookie is a file created by Microsoft Explorer and Netscape Navigator which resides in the preferences folder. It stores data about you, and enables servers you visit to keep track of what you search for and access. They can store this information in their databases for the purpose of marketing analyses and perhaps to generate mailing lists. Besides commercial uses, it's always possible that some servers out there could use this feature to simply record any of your comings and goings and do with the information what they will. We're trying not to sound too Orwellian, but you get the drift... Cookie Monster trashes the MagicCookie file every time it is launched. Install it in your Startup Items folder and Magic Cookie will do the rest. If for some reason you would like to reinstall the Magic Cookie, simply take Cookie Monster out of your Startup Items folder. For more info, you can lookup: http://pobox.com/~nicolas/monster.html http://www.illuminatus.com/cookie_pages/cookie.cgi http://www.bravado.net/rodgers/InterNetNews.html or netscape's technical page on the cookie standard: http://home.netscape.com/newsref/std/cookie_spec.html On Monday, July 29, Henry Rzepa wrote: >Netscape 3, under Options/Network/Protocols allows an alert to >be shown if a remote server has asked to write into your "cookie" >file.

Greek characters
by M.Winter＠Sheffield.ac.uk 26 Jul '96

26 Jul '96

Somehow this didn't get posted when I first wrote it and as I think it important, I'm sending it again Tip of the day Colleagues might like to know that NetScape version 3b5 and InterNet Explorer 2.0.1 (Mac versions, I don't know about other hardware) both support the display of Greek characters. Good news! This is some greek text Where I've written "symbol" you can write a comma delimited list of fonts and if one of them is available, presumably the first, then it gets used by the browser. Could someone please tell me what the font names are on non-Mac platforms that are equivalent to the Mac symbol font (which contains Greek letters)? *** (Extra: Explorer is now at 2.1b1 on the Mac) Dr Mark J Winter (Deputy Head of Department, Director of Studies) Department of Chemistry, The University, Sheffield S3 7HF, England tel: +44 (0)114 282 4498 fax: +44 (0)114 273 8673 e-m: M.Winter(a)Sheffield.ac.uk http://www.shef.ac.uk/~chem/staff/mjw/mark-winter.html WebElements is the periodic table on the world-wide web: http://www.shef.ac.uk/~chem/web-elements/ ----- chemweb: A list for Chemical Applications of the Internet.

VSEPR tutorial/guide available on WWW
by M.Winter＠Sheffield.ac.uk 26 Jul '96

26 Jul '96

I've just completed a first draft of a VSEPR package at http://www.shef.ac.uk/~chem/vsepr/ The Chime plug-in is preferred but not required. If you have any of Chem3D, Linus Lite, ChemDraw, RasMol, you can use them as helper applications, but these are not required. Browsers versions NetScape 3.0b5 or InterNet Explorer 2.0.1 are preferred but not required (except that earlier version numbers and some other browsers will not display Greek characters and symbols too well). Interactive calculations are a feature. I'd appreciate feedback.
