zwicky pages (so far)
Cześć wszystkim, (1) How to write in latin-2 on emacs: (1a) With a fairly new emacs (e.g. 20.7 or later): - M-x set-language-environment latin-2 - M-x set-input-method latin-2-prefix (also C-x <ret> C-\) - then can toggle input method with: C-\ Examples: `a`e`l's'c'o`z'z'n ąęłśćóżźń to stop ' being used, use, e.g., a space: ' a -> 'a (1b) You can put the following in your ~/.emacs file (custom-set-variables ;; custom-set-variables was added by Custom -- don't edit or cut/paste it! ;; Your init file should contain only one such instance. '(case-fold-search t) '(current-language-environment "latin-2") '(default-input-method "latin-2-prefix")) (2) The zwicky pages at the moment have a verrrrrrrrrry long URL: http://adjani.astro.uni.torun.pl:9673/zwicky/ Please see Tomek (czosnek) or me to create an account. pozd boud
hi all if it comesabout those wiki pages thtcan be modifien online I don;t think it's very secure since an authorisation goes over an external net (I watche the pages from my hause - and didn't log on deliberately) unencrypted. If one enters adjani hes free to explore further. maeybe that should be a seure page. pozdrawiam ******************************************************************************* Bartosz Lew e-mail: szajtan@astri.uni.torun.pl szajtan@phys.uni.torun.pl Centrum Astronomii UMK szajtan@poczta.onet.pl TORUN, POLAND www: http://www.phys.uni.torun.pl/~szajtan ******************************************************************************* On Wed, 6 Nov 2002, Boud Roukema wrote:

Hi Bartek, I think what you are saying is that the password used to modify a zwicky page could be read while it's passing through the net, and so other people could then use the password. Here's my response if I've understood you correctly: (1) the authorisation is handled by the server zope - we have "encrypt user passwords" enabled, so i think the passwords are... encrypted - if zope works as it says it does. (2) Even if someone *did* get the password, s/he would only be able to change the same pages that everyone else can change, inside of the zwicky folder. This is why later on we can consider having some pages modifiable by *everyone*. (3) The zope/zwicky login is *not* your adjani login. Your adjani password will certainly fail on zwicky. Tomek or I need to make you a login + allow access from your internet service provider (at the moment we're being ultra-paranoid and only local machines are authorised).

Not exactly. Encryption is only valid for storing password on the server's disk. But they are sent over network with open text. If we want encryption we have to run Secure Socket Layer as Bartek says. TL
Hello! I've got (perhaps silly) a short question. Vacuum is fulfilled by virtual particles (especially photons - I suppose). According to Heisenberg uncertainty principle - dE*dt>h/4*Pi or something like that. So virtual particle with energy dE exist dt seconds (in case there's no other particles nor magnetic field which could give for the virtual photon enough of energy to make it real). But energy of virtual particles is real. So can it influence on evolution of Universe? Can virtual particles appear in all points of space simultaneously? ,-,-, ,-, ,- ,- , ,. , ' ' ' '-- ' '- ' ' "
hi I think that virtual parcicles were introduced so they could explain some mechanims and stuff and to have such a thing that doesn't interact with (unless some special conditions - strong grav. fields in black holes outskirts) with nothing and doesn't influence on anything since they live so short. So in such approach this energy (which would be positive) even if maeybe real we cannot use in any way nor even distinguish it's presence (which is why we call the energy virtual). afterall I think we have enough problems with DE, DM, labmda, that why to bother with another form of energy :) ps. if I know well virtual particles borrow some energy from spacetime so this new positive energy would be balanced with some negative-energy debt in space, I quess. In case of no fields, virtual particles which appear always with their anitparticle counterpart would anihilate (canceling their bills with space) before rest of the world would realised (noticed) that anything happened. pozdrawiam ******************************************************************************* Bartosz Lew e-mail: szajtan@astri.uni.torun.pl szajtan@phys.uni.torun.pl Centrum Astronomii UMK szajtan@poczta.onet.pl TORUN, POLAND www: http://www.phys.uni.torun.pl/~szajtan ******************************************************************************* On Mon, 2 Dec 2002, Marcin Hajduk wrote:
