RE: i18n name badges

2003-11-20 Thread Rosen, Brian
Actually, I think RFID is much more expensive than bar codes, and
it's even more expensive the more you use it.

With barcode, you pay once for the readers.  Printing barcodes on badges
doesn't cost anything.  RFID tags cost money every time you make a badge,
plus the readers are what, 10X the cost of a barcode reader now?
RFID tags with storage are currently pretty expensive, and unnecessary, IMO.
Just a unique serial number and the registration database is sufficient.

I think we can make both optional.  Barcode is easily optional, just
don't swipe in.   I think you can easily lower the range of RFID so that
accidental swiping isn't likely.  You can also just decline to get the
barcode or RFID tag.

 It should be RFID, cheaper, and easier, not only for the blue sheets.
 
 The badge could be pre-configured with the data from our own 
 IETF registration.
 
 The badge will store the names of the people who we have been 
 talking during the week, and data like when, how much time, 
  We can then use an inexpensive reader to get a small 
 database out of it.
 
 Someone can complain about privacy issues, but I feel that is 
 the same now when the blue sheet is circulated, or the 
 attendance list is in the web site, right ?
 
 It will save a lot of time (money) to all of us, including 
 the IETF secretariat.

The problem with nroff is that there is no RFC to reference that
specifies how a document is formatted with nroff.  There is wide
variation in the macro packages people use to create a document
with nroff.  Even the RFC editor doesn't try hard to get the nroff
source when editing; they make their own. 

I'm also trying pretty hard to keep the word modest I used in the

 The value in this would be that it provides everyone with the document

 is useful,
 but if it's going to be allowed with XML then we should also allow it

If we have xml in the archive, then there are several tools
that can serve you up your choice of formats from that archive.
I don't think the value of storing the html bits in the archive
is all that much additional value.  One could have a website
that delivered such a thing without storing the html bits.
Such a site would permit the hyperlinking that you are talking
about.  We also avoid heated discussions about what was allowable
in the html, what version of which tools, etc.  This is a contentious
enough issue (rough consensus and running code applies, right?),
and making it bigger makes it harder to reach rough consensus.
Let's just do one simple thing -- allow xml, and see how it goes.

You make some good points.
However, I have not proposed that we change the RFC process,
and I've been very carefull to propose that we only accept xml
optionally, retaining the requirement to 'send text'.  I did so
quite deliberately, and I'd really appreciate it if we could
take this one small step, rather than changing the entire process,
which has served us well for so long.  We get a very large bang
for such a small, incremental addition.  Can we just try this

 One of the primary reasons for proposing XML as the canonical 
 RFC format
 is that these other formats (ASCII text, HTML, PDF/Postscript,
 refer/indxbib, SQL, Tektronix 4013) can be derived from the 
 XML source.
 
 Presumably the RFC editor would publish the XML document as the
 authoritative version, and would also generate and publish 
 (from the XML)
 alternative copies in the ASCII text, PDF, and HTML formats.
 
 This satisfies the plain ASCII text rules bigots (in which camp I am
 still firmly entrenched) while taking advantage of the markup 
 and linking
 facilities provided by PDF and HTML. (I've completely given 
 up hope that
 Microsoft will ever acknowledge that non-flowed text/plain must be
 rendered with a mono-spaced font, fifty years of prior art be 
 damned, eh?)
 
  (It may be that this is possible via XML as well -- I'm
  not expert in XML so I can't tell if its readily supported
  by everyone's browser without loading lots of DTDs. Does
  someone know?)
 
 The point of XML is that you don't have to be able to read 
 it. Given an
 XML DTD for RFCs, tools can be written that express the XML 
 in pretty much
 any format you like. HTML would certainly be one of those 
 formats. (And
 for guys like me who live and die by grep, even *I* would buy into an
 xmlrfcgrep program that provided grep functionality against 
 XML-RFC-DTD
 files.)
 
  And all of these submission formats should be allowed if
  and only there's a text version to go with it.
 
 Let me go out on a limb and say No they shouldn't; only XML 
 submissions
 should be allowed.
 
 
 
 Now that the shrapnel has stopped whizzing past my head, let 
 me explain
 why.
 
 The traditional way of writing RFCs is with nroff, typically using a
 minimal subset of the -ms macros. In recent years Microsoft 
 Word (along
 with other WYSIAWYG software) has invaded the traditional 
 UNIX typesetting
 tools workspace to a certain degree (in the context of writing
 IETF-related documents). Regardless, other than the 
 occasional Loonie who
 formats this stuff purely by hand, we are all already using markup
 languages to create these documents. That being the case, XML 
 isn't a new
 way of writing these documents, it's just a different one. 
 The current RFC
 DTD isn't complicated, and -- as long as it's kept simple[*] 
 -- I don't
 see any excuse for people not to use it. Then again, I've 
 been using troff
 exclusively for 20 years now, to the point where I can 
 _almost_ see the
 consistency of its syntax ...
 
 While there isn't a whole lot I *can't* accomplish in troff, 
 my experience
 with using it to write I-Ds suggests that those documents are so
 structured that I really just want to write a simple set of macros
 tailored for that task. I shudder to think what the Word crowd goes
 through in this regard. WYS might be WYG, but the path 
 between the two (in
 my very limited experience) is one whose mana will suck the 
 very sanity
 from your living soul.
 
 There is no argument to be made against the suitability of XML as the
 canonical format for authoring RFCs and drafts. Writing the 
 raw XML might
 not be pleasant, but neither is writing raw 'roff (or MS 
 Word) for many
 people. Let's embrace this as an opportunity. If we can get 
 the marketing
 twits to concentrate on selling GUI XML RFC authoring tools, 
 we just might
 be able to distract them from contaminating the actual working groups.
 
 --lyndon
 
 [*] The critical aspect is that the DTD *must* be kept 
 simple. If the DTD
 evolves into a Turing machine with Perl-like syntax we can just
 acknowledge that it's time to shut down the IETF and go home.

 the forlorn hope that people still know - and more importantly,
 understand - what the 'E' in IETF stands for.

RE: A modest proposal - allow the ID repository to hold xml

Is it not better to add xml incremental to text, rather than
exclusive OR?  If we demand that the I=D editor have a tool
and use it to generate text, we open a large box of problems.

What if the version of the tool the author used is different
from the I-D editor?  What if the xml is not well formed and
the tool does something unexpected?  What do we do when we
upgrade the xml schema (that is, do we have to go back and
edit older documents)?  All of these questions would have to
be answered, and answered well enough to satisfy some pretty
demanding people, some of whom are pretty content with the status quo.

My proposal avoids such discussions.  It makes no requirements
other than if xml is submitted, then it SHOULD be in conformance
to 2629.  

I also think it is MUCH better to start with the I-D archive and
not change the RFC process.  Among other things, I-Ds expire.
If this change doesn't work, in 6 months, we can be rid of any
vestiges.  RFCs don't expire (although they get obsoleted), and
the time frame is much longer.  Let's stick to I-Ds only, please.

  While I normally run in horror from all things XML, this is 
 one of the few
  exceptions. XML would immediately solve a number of 
 problems I face almost
  daily:
  
  - give me a list of all the documents belonging to a particular WG
  
  - for any given RFC, show me the chain of document dependencies
  (obsoletes, updated by, obsoleted by) that pass through 
 this document
  
  - for any given RFC, generate a dependency graph based on 
 the normative
  references in this document
  
  You have to have a structured document format to 
 programmatically solve
  these sorts of problems, and XML provides that. (While I've 
 become quite
  adept at searching rfc-index.txt with less, I really want something
  better.)
 
 May I add in the same direction ? The structure of the document allows
 for invoking relations between nodes, which helps for expressing
 elaborate search both on meta informations (WG, Author, etc.) and on
 content (the actual titles and text sections). You can surely look
 within all 'xmlly' available drafts for draft belonging to a specific
 WG AND referencing a list of specific docs in sections whose 
 title contains
 a specific word. This would be hard to express against the 
 txt version.
 
  And I second Ned's comments about generating *useful* diffs between
  document revisions. This is especially useful if we 
 generate drafts in XML
  format.
  
  I'm not sure how to address the problem with legacy RFCs. 
 I'll bet we
  could find volunteers to generate XML equivalents from the 
 existing plain
  text documents. (We would need an XML tag to indicate which 
 of the plain
  text or XML documents is considered authoritative.)
 
 I wonder whether this has not already been done by zvon
 (http://www.zvon.org/). Concerning referencing rfcs, citation 
 libraries
 from http://xml.resource.org look rather complete.
 
 Several additions to the xml cause:
 
 Edition in xml allows for good modularity, e.g. with the definition
 of xml entities. This is an easy way to divide work between several
 editors.  Availability of the xml source helps for editors to welcome
 new contributors.
 
 What I would suggest is the following:
   - Authors provide draft in xml XOR txt . This allows for a test
 period of xml as an alternate default format; authors do not
 provide both, this in order to avoid incoherences.
   - rfc editor generates txt, ps, etc. versions. html 
 version may only
 require reference to a stylesheet, though this is 
 currently tricky
 because few browsers actually support xml+xsl.
 
 Newcomers to xml should be informed of the following:
   - xml is easy.
   - Grammar/spelling tools compatible with html generally 
 work (I use
 ispell and aspell indifferently).
   - Document structure and well-formedness can be validated.
   - Maintaining an xml source is easy, compared to 
 maintaining a ASCII
 formatted txt: this is a point authors may care about.
   - xml rendering generates classic formats and newers: 
 this is what
 reviewers, readers care about.
   - xml users are not hackers, extremists or ninjas. 
 Common sense and
 good pratice is the main source of xml advocacy. 
 Also, xml is not
 perfect; it is only better.

Are you suggesting that we would need a new working group
to allow 2629 conformant xml to be optionally submitted with
text to the I-D archive?

Why?

I'm not proposing any new RFC.  Guidelines to authors is not
an RFC.  2629 is an RFC.

The xml2rfc tool, which is not the only tool around, but it's
a good one, puts a 70 line style header in front of the text,
but then has almost no other bloat that I can see.  Is that
too much?

I don't think there is any cruft at all in the xml described
in RFC2629.

Now, to the charge that this is feeping creaturism, we must
admit guilt.  I think there is some value in this proposal.
Many seem to agree.

RE: ASN.1 (Re: Pretty clear ... SIP)

2003-08-26 Thread Rosen, Brian
Good points, esp. the references to 2234.

May I also point out that many SIP stacks use automatically generated
parsers from the ABNF description.  These have many, but not all, of
the advantages claimed by ASN.1.  It was a goal of the RFC3261
work to make the ABNF grammar complete enough to use a parser generator.
Strict compliance to 2234 is helpful in this regard.

The proof is in the pudding.  Our experience with interoperability testing
is quite good, and contrary to statements on this thread, most current
systems interoperate with very old SIP devices.  This is more true of
old SIP phones than it is of old proxy servers.  If you use a time line
based comparison (age of spec vs interoperability results), I think you
would find SIP beats the pants off of H.323, which in the first several
years was dismal, but of late is pretty good. 

Also note that SIP is quite compressible, c.f. RFC3320, and the wireless
folks, currently one of the applications most concerned with the 
number of bits on the wire, seem quite content with compressed SIP, and
are not beating the doors down for ASN.1 encoding.

This version of the ASN.1 debate at least is focusing on PER.  The
last one I remember was the Megaco debate, which was BER based.  They
lost that one; the work showed BER encoded ASN.1 was both longer and
slower than text encoded.  With Megaco, you have directly comparable
messages.

 I have had people tell me that the post-1988 versions of

RE: presentation-prep as safety hazard

2001-03-21 Thread Rosen, Brian

Well, but 
Most PC designs use phase lock techniques which keep external
signals way below the CPU operating frequency
There are legal limits for radiation; most laptops and all  
 PDA devices are "Class B" which is a pretty low level.  
The real issue I suspect is that there is no practical way to test 
what the effect of a whole planefull of "at-the-limit" devices do 
to the plane's systems. It is very reasonable to design the avionics 
to be hardened against this sort of thing, but the older planes wouldn't 
have such avionics.

I expect we will see some lessening of the rules as the experience
and turnover of the airframes proceeds.  We already have the
"mobile use okay until pushback" which is a real change.

RE: rfc publication suggestions

2001-03-13 Thread Rosen, Brian

I didn't mean to imply the IESG is doing something wrong deliberately.

From personal experience, documents are approved by the IESG
that have unresolved IANA considerations.

From observation, documents are approved by the IESG that have
normative reference issues.

The next event is some months later, when the RFC editor picks
up the document, and authors are notified of the issues.  Are
you suggesting that in all, or even most of the cases, authors
are unaware of these issues before the RFC was approved by the IESG?

RE: rfc publication suggestions

2001-03-12 Thread Rosen, Brian

An interesting metric would be the time from the date something enters
a queue to the time its status is first changed - i.e. the first time
the editor looks at it.  I believe that is some number of months.  
Once the editor picks it up, then its time in queue is more a function 
of outside influence (waiting for others to do something), 
then internal processing of the RFC editor.

That's my recent experience anyway.

I'd love to have a discussion of:
What do we WANT the queue time to be
What would we have to do to get it there

I'd say that time to first action should be a couple of weeks to a month.
I'd also like to see if there were some more processes we could 
put in place so that the text never entered the queue until things
we KNOW have to be done, are actually done (like normative references,
IANA considerations,).  What happens now is silliness due to 
the known queue length - we put things in we know are deficient,
always assuming we will have the issues resolved before it wends it's
way through the queue.  Of course, it rarely works out that way,
and instead the RFC editor gets to be the nagging mother to us all.
Maybe we change the process so that a document is looked at
immediately for those missing things, and put in a hold queue
until they are resolved, and THEN they get into the "real" queue.
How much work would it be to scan the document for the normal
missing items?  Could we allocate people to do that as they
enter the process?

RE: HTML better for small PDAs

2001-02-28 Thread Rosen, Brian

Interestingly, 8.5 x 11 comes about because of writing, not reading.

Books are smaller than 8.5 x 11.  Tablets are 8.5 x 11, and typewriters 
copied that.  Laser printers copied typewriters.  Stenographers used smaller

tablets because they had to hold them in their hands rather than put them on
a desk.  Writing on a PDA is similar.

Reading is another story.  Turns out that line width is not all that 
important. No book has 72 characters per line, and no book has fixed pitch 
fonts.  All of that is a technology crutch, and horrible for readability.  
People who claim 72 character fixed pitch lines is for readers are smokin 
something funny.  It's left-over Hollerith card, with no basis in human
value.

Display technology has a really annoying reality - people always want more
resolution, but they pay close to nothing for it.  A great many companies
have
imploded because they believed people will pay a significant premium for a
better display (I imploded one or two myself, including a 300 dpi CRT
display
in '85). Just isn't so.

Display technology also is not subject to Moore's law - it's currently much,
much slower, and about 90% of the innovations have not turned into
commercial
realities.  Take every announcement of new display technology with a very
large dose of skepticism.

The biggest problem with PDAs today is contrast ratio, and that is fixable 
with more brightness, but has the problem of eating batteries.  You will 
probably see high contrast ratio, probably color, PDAs commonplace soon. 
They will increase resolution maybe 5% per year on average, but don't hold 
your breath on much more than that.  I can see displays that unfold once, 
like a book, but the idea that to read something you will unfold, and
unfold, 
and unfold doesn't seem like it will get very far.

If you want something to be readable, use a proportional font, don't worry
too much about line width, and increase your contrast ratio.

With respect to this discussion, it's not ASCII that's the problem, it's
the font and the fixed line width.  However, if we fix that, then a we
Get to fix several less important issues without any additional 
  complexity
but
We get all the problems of universiality, and archival storage

The solution has been obvious, but it has a cost we haven't figured out how
to pay.  The solution is to separate the functions of "source", "display" 
and "archive".  Source in XML, display in a variety of formats, including 
fixed width, fixed pitch ASCII.  Archive both the XML source and the ASCII.


The cost is that to be useful, we need tools to produce nroff markup from
XML source, because no one is ready to accept RFCs that can't be displayed
the way we display them now, and archive them the way we archive now.
Marshall's excellent work is fine for I-Ds, but it isn't enough for RFCs.
We need to produce pleasing ASCII, and the tool we use for that is nroff.
The tool and the DTD has to allow the overworked, and under appreciated
RFC editor staff to produce at least the same quality of ASCII output as
they do now, with no more than the current level of effort.  New tools mean
training, and that is another part of the cost.

We also have to create an XML archive from the current archive. 

Harald's suggestion of allowing ASCII and one other file to be archived for
I-Ds is a very reasonable, and very useful step.  He has a really good
point;
if we show that we will use another format, then we can move forward.
As soon as someone puts up a pleasing HTML render for the XML source,
that will be my preferred way to view I-Ds.  The indexing, reference,
and other side effects will also be welcome.

  You're thinking too traditionally. Displays will decouple from the

RE: 49th-IETF conf room planning

2000-12-13 Thread Rosen, Brian

On this subject, may I suggest that we have outgrown hotel conference
facilities.
The place where we have outgrown them is hallways -- hotel facilities simply
do not have adequate hallways to accommodate us.  Much of the value of the
meeting
is the impromptu "BOF"s that occur in the hallways and other open areas.

At this particular meeting, we compounded the problem by putting food
service
in the MIDDLE of the hall.  We also, in virtually the same area put the
registration area, causing close to illegal density of people.  This is just
unacceptable.

Why is that?

Seems to me it's part of the same issue, and technologically,
whatever solution you find for one ought to be pretty close
to the other, and if you do one, you should do the other.

I do think that just because a I-D expires, does not mean it
is unworthy of being preserved.  

Now the thread started with references to I-Ds. I do think
such references, except when used as historical references,
should be discouraged.  Certainly, I would not like to see
an RFC, especially a standard's track RFC, reference an I-D.
