Notes:
=====================
(1) Uwe Afemann, Internet - another panacea to solve the world's problems ?
http://www.rz.uni-osnabrueck.de/rz/special/misc/inet-3w/inet-3w.htm
(2) First standards for HTTP were established (by ITU) in 1992, for WWW using
HTML in 1993 (by the predecessor of the now standardising body, W3C or World
Wide Web Consortium).
After sufficiently many "Internet Service Providers" (ISP), i.e. points of
access to the Net by individual users, had installed HTTP - and after
sufficiently many ISP had established and offered dial-up access publicly -,
the year of 1994 is now considered as the break-through date for the Web.
(3) Historically and functionally, HTTP has merely been a specific,
standardised set of commands for file retrieval according to the File Transfer
Protocol (FTP) long existing; only the (usually) coupled application of a
program which interpretes the mark-up (in HTML) of the text file thus
retrieved, constitutes the specific category of (Inter)Net use. The basic
functions of Net use are:
Telnet (use of the basic Internet protocol, TCP/IP, and a packet
driver on the individual client side, of a simple BBS-like,
quasi-direct telecommunication connection)
SMTP (Mail send/receive), later POP3
NNTP (Newsgroups messages retrieval)
FTP (file transfer and retrieval)
Gopher (an FTP based, menu-driven file retrieval system depending
on servers responding to the specific client demands; has
been marginalised by HTTP/WWW use - and server set-ups -
despite its faster and much less cumbersome file/content
transfer capability)
Finger, and Ping/ICMP
IRC ("chat" via keyboard, originally as a mode of Telnet use)
Server functions: -- Time (& Daytime synchronisation)
(ISP or backbone) -- Address/Domain name resolving
-- Routing (the most important of all,
costituing the "net" property)
HTTP (and additionally, on the server side, CGI) i.e. processing
of WWW addresses and client/server demands; all additional
task of WWW/HTML, including processing of audio-visual
elements, are strictly browser dependent presentations of
HTTP-transported files on the client side.

(5) The whole industry, and even regulatory bodies like the EU Commission or
the ITU, expect unbroken optmistic increases of lines and channels to be
available, and of exponential growth of transfer volumes (in terms of content
as well as monetary value). Some scepticism seems appropriate though - taking
the example of mobile telephones, the "population" of users was almost
completely recruited from the one already connected to conventional telephone
networks. Real new recruitment concerned economical elites in infrastructure
deprevated regions with comparably high popolation density - capital cities
in some African countries, Eastern Europe - where conventional telephone
systems have broken down.

(7) Rather ridiculous examples may be found, of all places, at the "text_only"
www-sources for the BBC's "Newsroom", the textual presentation of news
features of the British BBC World Service radio(!). (Wrong) use of the
HTML-"Table" elements, of colour attributes and the like, bloat the text of a
simple news feature from 4,304 bytes to a 49,734 bytes HTML "document" to be
downloaded. A sober - and appropriate - HTML mark-up would hardly add more
than some hundred bytes to the original. Ever so, a random sample of HTML
marked-up text items from that same source showed an increase of a quarter of
the byte volume by the HTML-marks alone, and and increase of more than 300
per cent in volume between the the sheer text content of items - certainly
line- and paragraph-formatted for good readability on a screen - and the
final HTML-marked up page. (cf http://www.news.bbc.co.uk/text_only.htm)
(8) Another example of inherent irrational development may be seen with other
recent technological innovations, fax and Optical Character Recognition (OCR).
The motive to develop OCR and its primary use for humans, it would seem, should
be the access of the blind to written sources. It is not; its "economical"
raison d'etre is to re-transform printed characters which originally had been
stored and presented as bytes and transformed to print style, into stored bytes
again. Almost amusing is the process where "word-processing" equipment and
software is used to produce paper sheets which then are transmitted from a fax
machine to another only to be read in by OCR hard-&-software there again in
order to be "processed", read and stored.
A global economical assessment might be rather damaging, not to speak of
incidental ecological charges to our limited resources (bloat of paper
consumption in general, and of that of the environmentally dangerous fax paper
in particular). The perfectly appropriate technology of the first-generations
PCs would do the job probably for a fraction of total "costs", and without
the additional equipment for OCR. It may be reminded that these are real,
social costs: resources spent on the means of organisation of our societies
are taken from the available surplus value of productive work, and they are
lost for other, meaningful employment, even if some (minor) parts of the
economy - say, paper, fax, and scanner producers - may have their particular
profit from it.
(9) ARPA, the US-military network of linked (computer-)information sources,
certainly had the function to serve a power-centered and hierarchical
institution originally - even if this was a "public", but nontheless
secrecy-obsessed one. Its very contruction however, as a completly
decentralised, non- (or even anti-)hierarchical system made it nearly "by
nature" a public thing. Once opened, the public of that time accepted it as
such and contributed, again in a totally decentralised way, to its development
and expansion. Much of what followed then may be interpreted as a
permanent attempt to catch and cage the swarming birds (cf. the debate on
privacy and censorship, concisely resumed in that respect in Katja
Diefenbach, Kontrolle, Kulturalisierung, Neoloberalismus, in: P.Schultz, Ed.,
Netzkritik. Berlin: Edition-ID-Archiv 1997)
(10) A tentative classification of "key actors" could look like this:
-- owners/administrators of physical infrastructure:
-- basic infrastucture -- telcos
-- backbones/nodes (big) servers
-- ISPs=interfaces -- (smaller/local)servers
-- regulators:
-- on infrastructure (basic/technical telco functions)
-- on material access -- (at first) by public instances:
administrations, universities,
libraries
-- on their material support
(i.e., budget authorities)
-- on physical inter-operablity (ITU)
-- on software interoperability (ISO/W3C,ITU,...)
-- on "content" (public legislators/judiciary)
-- hardware/software producers -- for intermediary use (ISPs/backbones)
-- terminal/end-user use (machines as well
as applications)
(11) The "
" element of HTML mark-up has in all versions clearly been
defined for what is says, the ordered row/colums presentation of (variable but
volume restricted) tables, and has been recommended to not be used for
general page-layout tasks. This is arguably the most abused mark-up tools of
all though, and it plays havoc with screen readers for Braille output. But
this is very much a problem of professionalism of web site designers, and a
task for supervision by their superiors.
(12) Which is patently wrong - "FRAMEs" can be read by even the most primitive
versions of text/line browsers sequentially, so this should not be used as a
pretext to bar access to their contents.
However, the - "legal" and standardised - procedure allone of the web site
server to identify the type of client (the name/type of the browser used by a
visitor) raises a number of more fundamental questions of privacy, personal
data identity/determination and more (not to speak of "proprietary" properties
of servers to use "proprietary" qualities of a client's browser to manipulate
the client's machine, like "cookies").
Of quite another nature is the argument about how far a Web designer can or
may determine the complete end-product of "presentation" on a client's screen.
The intention to make it come out "best" - in terms of presumptions of
the clients' browser capacities - is equally legitimate as the users' choice of
browser programs (or ability to choose/employ such). Under condition of equal
footing this would not produce a problem of basic accessibility, as both
sides could balance advantages of "better" screen presentation for secondary
attributes.
(13) There is a factual, but slowly less rigid link between hardware equipment
and software employment specificly in respect of the basic operationg system
with INDIVIDUAL PCs. Because of the INTEL CPUs' memory addressing limits and
modes, PCs of the pre-80386 type could not use alternative operating systems to
the Microsoft-DOS or MS-Windows(=DOS) type (though there had been and there are
alternative, MS-DOS compatible OSs, which by-pass those problems -
but the later NS/MS browsers never were adapted to them). Apple, with its
"Macintosh" the main alternative of hardware-plus-OS stand-alone PCs, saw a
steady decline of its market share, from about 15 % of NEW PCs sold in the
beginning of the '90ies to about half of that in later years (but less so in
absolute numbers), and in any event the NS/MS browsers were always late to be
adapted to the Apple-Macintosh OS. IBM's own, new "OS/2" only came off the
ground, and rather slowly, with the "Pentium" CPU generation. The UNIX-type OS
was designed from the beginning for "big" computers, using individual PCs only
as (relatively "dumb") end-user terminals, connected mostly (at first) via
Local Area Networks (LANs) of the Ethernet type and pertinent additional
hard- and software (from another near-monopoly, Novell) - but basically any
DOS-run PC could serve in this environment, and connected to the large
university networks, still to-day quite a large number do, but these are
unaccounted for in any statistics. LINUX, a completely non-commercially
developed UNIX-type (and compatible) OS however, has gained steadily ground on
the user-side, but again this is mostly unaccounted for in the usual
"market"-statistics of PC-sales with an OS installed (users just replace that
with the nearly cost-free LINUX); UNIX/LINUS does require at least the
past-1992 generation of INTEL 80386 CPUs however.
All this boils down to a rather steady share of non-MS-DOS equipped "sales of
new PCs" in the range of 15 % of the total; with an overall increase of that
total. Only in that respect the publicity claim of Microsoft of having 85 % of
PCs "installed" with their OS (and until now, all "Windows" versions are MS-DOS
based too) may be true. It does not say anything about how and with what OS,
and if, with what "Graphical User Interface" (GUI, for instance MS-"Windows)
these PCs then effectively are run - a rather recent report, based much on
Microsoft/CH's own data, concludes that "about half of all" PCs in Switzerland
are run under MS-"Windows" and MS-"Windows-NT" (WochenZeitung, Zurich: 8.1.98).
According to the French Microsoft office, after a first year of "Windows-95"
sales "43 % of new PCs sold" were equipped with that software. (De Morgen,
Brussels: 23.8.96)
(14) The first was quoted from Microsoft publicity in a commentary of the
"Gaurdian" newspaper at the occasion of the anti-trust procedure then in course
in the USA, the second quotes the then newest update of the publicity page of
Caldera, an independent DOS operation systems producer; both date from the last
week of December, 1997.

Typically, "Online Services" exclusively named commercial providers and
did not consider semi-public access (e.g., universities, libraries) or
publicly available, non-commarcial access accounts (eg. the rather large
networks like APC in GB, Comlink in Germany); not to speak of those
interlinked BBS networks which, like the FIDO or Zerberus networks, at that
time offered already all Internet functions but WWW access (and some of them
even that).

(24) This is rather absurd particlularly in Germany where the mail-order
market for the substantial private/individual use of PCs is much more
developed than in France or Belgium, where PC sales to a much higher degree
are oriented towards the "office" use.
(25) From a usenet discussion, Tue, 15 Jul 1997:
"Subject: Re: Discrimination of non-illiterates
>> Installing WINDOWS in an office is illegal... it violates the
>> "Americans With Disabilities Act" in that though the pretty
>>pictures for the illeterate are nice... The blind can't read
>>them and have to have a TEXT based system such as DOS.
>
>Is this real (or wishful thinking) ? Has there been a (test) case ?
At the moment it's both. The law is real, but nobody has tested it
yet. So far companies like LOTUS (makers of 1-2-3) have managed to
buy off the victims of WINDOWS in their offices far as I know.
But considering the damage that windows is doing to me (Server carpal
tunnell made much worse by using that stupid electronic rodent) I'd
love to see it happen.
Oh, yes... There are a few attornies on INTERNET and most of them
(all the ones who have responded in fact) feel it might be a good
case. Emphasis is on the word MIGHT however."
Note: There are precedences of disabilities-related, or outright disabling
cases. The "Financial Times" for instance had nearly a third of editorial
staff affected by RSI, had to pay heavy indemnities for some permanent cases
and was forced to replace the used corporate system with ergonomically harmful
screen hardware (and screen presentation software) and keyboard equipment.
Cases like these are considered relevant for later procedures on disabl*ING*
conditions.- Germany has a constitutional provision (article 3, para 3 of the
"Grundgesetz", a directly appliccable clause against discrimination on
grounds of disabilities or handicaps) but despite of some 12 to 15 thousand
blind computer users, there had been no testcase (yet).
(26) An example e.a., is the EU Commission server for press releases,
http://europa.eu.int/en/comm/spp/rapid.htm. The European (ministerial) Council
(http://ue.eu.int/angl/newsroom.htm) sends text-only using clients to the
commercial site of Netscape to download and install that browser first in
order to access the (pure text, and all text) content of its official
communications.
