04/15/2005 02:47 AMI was stunned to receive the notification from a Microsoft
spokesperson regarding "a new Office Online column from Jeff Raikes on
real-time collaboration," only to learn that there was no way for me
to subscribe to Raikes’?musings via RSS. Instead, I guess I’ll
have to remember to check Microsoft’s site on a regular basis for
anything new, or wait for the next e-mail.?How inefficient!
Speaking of efficiency, perhaps that’s the silver lining to this
cloud. Raikes’ note describes how Microsoft, being the large
international company that it is, has been a pretty good proving
ground for how its enterprise collaboration tools (Communicator, Live
Communications Server, and Live Meeting) can grease the wheels of
group productivity while saving the company money. Against a backdrop
of presence detection and management and context-sensitive
communications, Raikes says, "At Microsoft, we have more than 35,000
people using Live Communication Server-based IM and we send roughly
7.5 million instant messages per month." Using the financial returns
as another proof point, Raikes writes, "Live Meeting is used
extensively within Microsoft and it provided immediate returns. At
Microsoft in FY04, Live Meeting replaced 1 in 5 business trips and
saved the company over $40 million U.S.; in FY05, that savings is
expected to top $70 million."

More on RSS bandwidth consumption
More on RSS bandwidth consumption
07/21/2004 11:02 AMA few months back I wrote about RSS
bandwidth consumption, and this subject is again in the news
following Chad Dickerson's recent InfoWorld column about his love/hate relationship with
RSS. Dickerson notes that desktop RSS readers which hit a feed too
frequently - and then download the feed even when it hasn't changed -
are resulting in a huge server load.
However, as Dare
Obasanjo points out, many of those complaining about RSS bandwidth
consumption fail to configure their own servers to address the
problem. Dare shows that InfoWorld's feed supports neither GZip
encoding nor conditional HTTP Get, both of which would
dramatically decrease RSS bandwidth consumption. The
latest RSS reader stats show that all the major ones support these
techniques, so make sure your server (and/or the feed itself) supports
these techniques. If you have a static feed, chances are your server
handles this for you - but if you have a dynamic feed (i.e.: one
created on-the-fly with PHP or ASP), you may need to make some
changes.
In the past, raising this topic has been followed by naive calls to
stop using desktop RSS readers in favor of web-based applications,
since web-based aggregators consume less bandwidth. I'm far too
biased to argue about desktop vs. web aggregators, but the argument is
moot since many people find the UI and feature set of web-based apps
too limiting for their needs and will always want a
desktop application (witness Outlook vs. HotMail). Arguing for either
type of application is pointless, since each will be around for a long
time.
BTW, I'm glad to see that Sam Ruby is proposing updating the Atom spec and the feed validator to support HTTP
conditional get. My guess is that a lot of bandwidth will be saved
once the feed validator warns about feeds that don't take advantage
the If-Modified-Since and If-None-Match HTTP headers.
Oh, and since I mentioned RSS reader stats, I have to get this off
my chest: server stats are not an accurate representation of the
popularity of individual RSS readers. A number of RSS readers default
to checking for updates every hour, whereas FeedDemon defaults to
checking every three hours. So, three times as many
people would need to use FeedDemon for it to be ranked equally with
these other apps.
RSS readers and bandwidth consumption
RSS readers and bandwidth consumption
05/04/2004 12:32 PMWired recently asked wh
ether RSS readers will clog the Web, raising concerns about
bandwidth problems associated with RSS. While these concerns are
valid, they're really less about RSS and more about the poor design of
some RSS readers. So, I'd like to point out how FeedDemon was
designed to minimize bandwidth consumption.
The primary concern is how often RSS readers download feeds to
check for new items. After all, if a feed is updated once a day,
there's a huge waste of bandwidth if RSS readers are downloading the
feed every few minutes. However, a well-designed RSS reader won't
download the entire feed if it hasn't been modified - instead, it will
do as FeedDemon does and utilize HTTP If-Modified-Since and If-None-Match (ETag) requests. If the feed hasn't changed, then
the server simply returns a 304: Not Modified response,
which requires very little bandwidth. FeedDemon also
supports GZIP
compression and it remembers redirects, which further reduces
bandwidth consumption.
FeedDemon honors the RSS <ttl> element, which enables feed authors to state
how often the feed should be updated. FeedDemon won't allow setting a
feed's update frequency lower than the <ttl>, so be sure to use
this element in your feed if you're concerned about unnecessary
bandwidth consumption. In addition, FeedDemon honors the <sk
ipdays> and <skiphours> elements.
And I should add that FeedDemon defaults to checking for updates
every three hours, not every few minutes. Users can set the update
frequency lower than this (provided it's not lower than the feed's
<ttl>), but in my experience, few users actually do this.
So, while RSS bandwidth consumption is a valid concern, it's a
concern that I addressed from the very start when designing
FeedDemon.

Dynamic RSS Feeds and Bandwidth
Consumption
Dynamic RSS Feeds and Bandwidth
Consumption
09/09/2004 01:08 PMScoble has been writing about RSS
bandwidth concerns lately, so I thought I'd once again post on
this topic. I've poste
d befor
e about using conditional HTTP Get
(If-Modified-Since) to decrease RSS bandwidth
consumption, but here's a simple recap of how this works:
Almost all aggregators store the date/time that a feed was last
updated, and they pass this to the HTTP server via the
If-Modified-Since HTTP header the next time they request
the feed. If the feed hasn't changed since that date/time, the server
returns an HTTP status code 304 to let the aggregator know the feed hasn't
changed. So, the feed isn't re-downloaded when it hasn't changed,
resulting in very little unnecessary bandwidth usage.
This sounds simple enough, but there's a big problem here: many
high-traffic RSS feeds are created dynamically through server-side
code, and the HTTP server won't automatically support conditional HTTP
get for dynamic feeds. So, all too often the feed is rebuilt each and
every time it's requested - which is obviously a huge waste of both
bandwidth and CPU time. One solution is to write your own code to
return a 304 based on the If-Modified-Since header, but
in many cases it makes more sense to use a static feed that's rebuilt
only when new information needs to be added to it. For example, my FeedDemon FAQ
feed is a static RSS file that's rebuilt whenever I add a new
entry to the
FeedDemon FAQ. This way, my HTTP server takes care of the
If-Modified-Since comparison, and there's no unnecessary
regeneration of the feed.
However, while this works well for feeds that don't require many
updates, it's not the best approach for feeds that need to be updated
more frequently. This is the problem I faced with my support forum feeds, which
are created dynamically from information stored in a SQL Server
database. Since new forums posts are often made every few minutes, I
decided to use server-side code to limit how often aggregators can
download the feeds. Almost all aggregators support conditional HTTP
get, so I simply check the If-Modified-Since date/time,
and if it's within the last 15 minutes I return a 304 to tell the
aggregator the feed hasn't changed - even if it has. This essentially
limits aggregators to checking for updates more often than every 15
minutes.
Here's a snippet of the ASP.NET code I use to do
this:
Dim dtNowUnc As DateTime =
DateTime.Now().ToUniversalTime
Dim sDtModHdr = Request.Headers.Get("If-Modified-Since")
' does header contain
If-Modified-Since?
If (sDtModHdr <> "") And IsDate(sDtModHdr) Then
' convert to UNC date
Dim dtModHdrUnc As DateTime =
Convert.ToDateTime(sDtModHdr).ToUniversalTime
' if it was within the last 15 minutes,
return 304 and exit
If DateTime.Compare(dtModHdrUnc, dtNowUnc.AddMinutes(-15)) > 0 Then
Response.StatusCode = 304
Response.End()
Exit Sub
End If
End If
' add Last-modified to header - FeedDemon
stores this with cached feed so it's
' passed to the server the next time the
feed is updated
Response.AddHeader("Last-modified",
dtNowUnc.ToString("r"))
Now, I'll be the first to
admit it's not the most elegant hack, but so far it has worked very
well for me. I considered checking the date/time of the most recent
forum post and using that for the
If-Modified-Since
comparison, but that would've required a database hit each time the
feed was requested, so I opted for the less precise but more
CPU-friendly solution.

07/24/2004 09:20 AMRemember when emails were flying around about the sulfnbk.exe virus?
It began on the internet, spread like wildfire, and eventually made it
all the way to the cable news channels. It turned out, of course,
sulfnbk.exe wasn't a virus. It's a program that backs up long
filenames created by Windows, but few people bothered to look it up
before deleting it. As a result, the more unfortunate victims were
puzzled to find some DOS programs had rendered many of their file
names illegi~1. Less a computer proficiency deficiency than an
aversion to independent thought, the sulfnbk syndrome seems to repeat
itself with unfailing consistency. The story you're about to read is
just the latest permutation.

Ebooks doing well sans DRM
Ebooks doing well sans DRM
08/27/2004 01:46 PM
Cory Doctorow:
CNet reports that ebook sales topped 3 million last year, and that
publishers are slowly coming around to rejecting DRM. The best part is
that famous writers like JK Rowling are rejecting ebooks, a courtesy
that leaves the field open for struggling midlist writers (ahem).
Bad experiences with heavy-handed DRM have soured many potential
customers on e-books, said Mike Violano, vice president and general
manager of eReader, which equips its titles with a security key based
on the credit card number used to purchase it. The approach give wide
latitude to the original buyer while effectively thwarting illegal
copying, he said.
"There are far too many standards and ways of doing things now, and
that's a source of frustration for customers," Violano said. "If they
have a bad e-book experience the first time, where they have trouble
reading something they've paid for, it's hard to get them back."
Analyst Bedford said nervous publishers have emphasized security over
opening new markets.
"There's no good DRM, period," she said. "Publishers all want
heavy-duty DRM, but the problem is that anything you do gets in the
way of buying and using e-books. My bias is to use a lot of
psychological DRM. You put a price on it; you have statements...making
it very clear you can use this as you would a print book, and you rely
on the fact that by and large, most people aren't out to break the
law."
