The "Bazaar" style of project management, as
described by
Eric Raymond and typified by the Linux kernel development model, is
undoubtedly effective at producing quality software, at least in some
situations. It can also, however, be a harsh environment in which to
operate, as demonstrated by events in the kernel community over the 2.5
series, and especially over the last week.
Readers of the LWN.net weekly Kernel Page will have been following the
development of the IDE/ATA layer in the 2.5 series for some time. For the
rest, here is some quick background to provide context for the rest.
The IDE layer, of course, is the low-level code that handles the disk (and
CD) drives found on most Linux systems. This code operates under a number
of serious constraints. It must be fast - able to drive the hardware at
its maximum speed; the performance of a Linux system as a whole is highly
dependent on how fast its disks can go. It also must be absolutely
correct; users get grumpy when their data is lost or corrupted. And it
must deal with a wide variety of, um, "inexpensive" hardware that does not
always behave as the documentation and standards say it should. Hacking on
the IDE subsystem is not for the faint of heart.
In recent times the IDE maintainer has been Andre Hedrick. Andre has had
numerous communication problems with Linus (and others) which have made it
difficult for him to get patches into the kernel. It is also fashionable
in certain quarters to criticize the quality of Andre's code. But, it
should be said: Andre's IDE layer has proved, over time, to be rigidly
standards compliant and highly reliable.
Andre's inability to get patches into the kernel left a void in the 2.5
series, however. That void was filled by Marcin Dalecki, who started
posting his "IDE cleanup" patches back in February. The "cleanups" began
to look increasingly like a complete rework (and hostile takeover) of the
IDE code, and, with IDE 18, Marcin put
his name into the MAINTAINERS file.
Marcin's work has been controversial all along - especially after he
started removing features that people were using, and when the IDE layer
started breaking for some users. His approach was not subtle, and he
seemed untroubled by the concerns of the other Linux kernel hackers. After
all, said
Marcin, "Breakage is the price you have to pay for
advancements."
Linus, for the most part, seemed to agree; he merged almost every patch
from Marcin through IDE 115, posted on
August 9.
All this changed on August 16, when Linus, without fanfare, deleted the
entire 2.5 IDE subsystem and replaced it with the "foreport" of the 2.4 IDE
layer, done by Jens Axboe and others. The word from Linus is that Marcin
got tired of all the criticism and quit; Marcin, himself, has been silent
since then. It is telling, though, that Linus responded by simply deleting
and replacing the entire body of 2.5 IDE work, rather than trying to find
somebody who would continue that task. Either Linus came to agree with
other kernel hackers about the quality of the reworked IDE code, or he
concluded that nobody else would be willing to work with that code.
The end result is that six months worth of Marcin's work, in the form of
115 IDE patches, has just been dumped into the bit bucket.
And that is an example of the harsh side of participating in the
kernel bazaar. One can work for months, see that work apparently accepted,
then have it vanish in a moment. Linus has said numerous times that the
doesn't much care about the feelings of kernel hackers; he is far more
concerned about the quality of the code. This approach may well be part of
why Linus is a good manager for Linux development - in the end, the code
quality must remain high or the whole thing will collapse under its own
weight. But it also explains why kernel hackers occasionally get
frustrated and leave the kernel development community. The bazaar can be
fun and effective, but it's not always nice.

The GNOME project has
announced
the release of version 1.0 of the GNOME Human Interface Guidelines (HIG). The
HIG is, according to the announcement:
...the most complete and carefully researched document of its kind
in the Free Software community [and] a major step
toward the creation of an easy to use and powerful set of free
applications with a distinctive and coherent style.
Leaving aside the hype, some examination of this 130-page document shows
that it is, indeed, an impressive piece of work. The HIG examines many
aspects of the usability of graphical applications, from window layouts,
color selections, icon design, etc. through to things like how to label
menu entries. A simple example of the sort of work that has been done:
User testing of MIT's Athena system revealed that users had
difficulty finding the file manager because they were unfamiliar
with the name "Nautilus". Because users did not associate the word
"Nautilus" with the concept "file manager" the menu item did not
help them.
Like many things in the usability arena, this conclusion seems obvious - in
retrospect.
Even after years of human factors research, creating highly usable
applications still requires a great deal of plain hard work. Application
designers are often blind to things they do that confuse their users.
Creation of the best desktop applications available requires more than just
great hacking; it requires serious attention to all of the little things
that make those applications really work for the people who will use them.
The HIG, thus, is a great contribution to the free software community, in
that it will help to focus and guide that attention.
The HIG is also the sort of work that free software developers are not
supposed to be good at. What self-respecting, ego-driven, itch-scratching
free software hacker is going to bother with human factors research, after
all? Such claims have been increasingly hard to defend for some time; the
HIG is just one more example of what the free software community is really
capable of.
One other quote from the announcement is worth a look:
Further, we would like to challenge the KDE project to serve the
general user community by partnering with us in developing these
guidelines to create a common Free Software interface style.... We
call on the members of the KDE project to rise above Not Invented
Here (a natural tendency that neither project has been particularly
succesful in repressing, we know) in taking a major step for the
good of both our user bases and the long term success of Free
Software on the desktop.
A true gesture toward cooperation could certainly have been done in a less
public and challenging way. It is true, though, that the creation of a
common interface document could be a good way for the two projects to work
together. The creation of a more consistent desktop environment across the
two projects would help both - as would a more formal approach to human
factors in general. And both projects could join this work while
maintaining their own code bases. It's worth some thought.

There is not a whole lot to report this week with regard to LWN's status
and life expectancy. We are still in "discussions" with our credit card
clearing company. We are still hacking on the subscription code (it's
mostly complete) but are not sure if we will be able to accept credit cards
to pay for those subscriptions. Hopefully all of this will settle out
before too long. Meanwhile, we're doing what we can to continue to produce

Here is
an advisory from the KDE project
regarding a flaw in Konqueror's digital certificate handling. It seems
that Konqueror (along with certain other, proprietary web browsers) doesn't
look hard enough at how a site's certificate was signed, meaning that
anybody can fake a certificate for anybody else's site. Thus, with a
little additional trickery, it would be possible to set up "man in the
middle" attacks and steal credit card numbers.
The Register described this
vulnerability as "a colossal stuff-up." Certainly the error is worth
fixing, but anybody who is greatly concerned about this vulnerability would
be well advised to look at the end of the "Certificates and Credentials"
chapter in Bruce Schneier's Secrets & Lies:
I visited www.palm.com to purchase something for my PalmPilot.
When I went to the online checkout, I was redirected to
https://palmorder.modusmedia.com/asp/store.asp. The SSL
certificate was registered to Modus Media Internatinoal; clearly a
flagrant attempt to defraud web customers, which I deftly uncovered
because I carefully checked the SSL certificate. Not.
All that SSL does in almost every use is to verify that the remote site has
a certificate issued by a trusted authority. There is no verification that
said certificate has anything to do with the site that the user expects to
be interacting with. Man in the middle attacks are easily done even when
the web browser properly checks how digital certificates were signed; the
Konqueror vulnerability has not really opened up any new holes.
The real issue, which nobody is all that concerned about, is that the
digital certificate system is not doing much for its users. Quoting
Schneier again: "Digital certificates provide no actual security for
electronic commerce; it's a complete sham." Konqueror users should
go ahead and apply the patch (see the LWN
vulnerability entry for distributor updates as they arrive), but it's
not going to make them all that much more secure against man in the middle
attacks.

Bruce Schneier's CRYPTO-GRAM newsletter for August is out; it includes a
look at Palladium, the proposed law allowing attacks against online
copyright violators, and the idea of arming airline pilots. "
To me,
it's another example of the insane lengths the entertainment companies are
willing to go to preserve their business models. They're willing to
destroy your privacy, have general-purpose computers declared illegal, and
exercise special vigilante police powers that no one else has...just to
make sure that no one watches 'The Little Mermaid' without paying for it.
They're trying to invent a new crime: interference with a business
model."

PHP Remote Compromise/DOS Vulnerability
| Package(s): | mod_php4 |
CVE #(s): | |
| Created: | July 22, 2002 |
Updated: | February 18, 2003 |
| Description: |
PHP 4.2.0 and 4.2.1 have an error in the handling of POST requests which
can lead to the corruption of memory, and the usual bad consequences. According to this alert, the vulnerability can only be used for denial of service on x86 systems - there is no way to get it to run exploit code. SPARC/Solaris systems are apparently vulnerable to full remote compromise.
According to the CERT Advisory,
almost every Linux distributor, it seems, ships older (and thus not vulnerable) versions of PHP.
Note that, sometimes, systems thought to be safe from remote compromise turn out to be vulnerable to a modified attack, so x86 users should not relax too much. The solution, for those systems with PHP
4.2.0 or 4.2.1 installed,
is to upgrade to PHP 4.2.2.
For more information see the alert from
the discover of the vulnerability, Stefan Esser of e-matters GmbH,
or the security
advisory from the php team.

Kernel development
Brief items
The current development kernel is still 2.5.31; Linus has not
released a development kernel (as of this writing) since August 10.
Linus has not been idle, however; his BitKeeper repository (which may well
be released as 2.5.32 by the time you read this) contains many
changes. At
the top of the list, of course, is the replacement of the IDE subsystem.
Other stuff merged by Linus includes some NFS changes, the "scalable exit"
patch from Ingo Molnar (see below) along with his other thread support
improvements, an ACPI update, a set of page cache improvements from Andrew
Morton, a new MTRR driver, more device model work, a new RTC driver, and a
very long list of other fixes and updates.
The latest 2.5 status summary from Guillaume
Boissiere came out on August 20.
The current stable kernel is 2.4.19. Marcelo released 2.4.20-pre4 on August 19; the biggest
change in this prepatch is the addition of the JFS journaling filesystem.
The current prepatch from Alan Cox is 2.4.20-pre2-ac6. The "ac" series looks to be
the testing area for new IDE
patches for some time, and thus may be, at times, less stable than people
have come to expect.

Kernel development news
As covered on this week's front page, all of Marcin Dalecki's "IDE cleanup"
work has been removed from the 2.5.32 kernel and replaced with the 2.4
"foreport." That leaves the IDE code in a state not that far removed from
where it was when the 2.5 series started, and the Halloween freeze date is
getting closer. What is going to happen to the IDE code now, and who will
do it?
At the moment, nobody is stepping forward to be the next IDE maintainer.
For the time being it looks like Jens Axboe and Alan Cox are willing to
oversee new IDE work and filter it on its way to Linus - but they will not
necessarily do a lot of that work themselves. Alan has laid down some conditions, though:
I want order to this. That means all the driver cleanup goes into
2.4-ac (or "2.4-ide" or some suitable branch) first where we can
verify we aren't hitting 2.5 generic bugs and ide corruption is a
meaningful problem report. It means someone (not me) is the
appointed 2.5 person and handles stuff going to 2.5 (I'm happy to
identify stuff that tests ok in 2.4 as candidates). It also means
random patches not going past me.
If we can do it that way I'll do the job. If Linus applies random
IDE "cleanup" patches to his 2.5 tree that don't pass through Jens
and me then I'll just stop listening to 2.5 stuff.
In other words, the 2.4-ac tree becomes the development area for new IDE
work before it heads into 2.5. And Alan doesn't want to have to contend
with patches taking other paths into 2.5. (Alan has also posted the set of attributes an IDE maintainer should
have for anybody who is interested in the job).
What is going to happen with the IDE code? A few people have requested
that somebody pick up Marcin's work and finish the job, but nobody who is
actually working with IDE seems to have much interest in that. Quoting Alan again:
Its easier to go back to functionally correct code and do the job
nicely than to fix the 2.5.3x code. Right now I'm working on
Andre's current code in 2.4.20pre2-ac* starting off with only
provably identical transforms between AndreCode and C and
documenting it
So it looks like the 2.4 IDE implementation is here to stay. Or, at least,
something based on it - Andre Hedrick, as it turns out, has not been idle
during this time. He has a whole set of patches - much of which is already
in the -ac series - for nice things like Serial ATA, pluggable low-level
transport drivers, modular chipset support, etc. At this point, it's hard
to imagine this code not moving into 2.5 once it proves stable.
Linus has his own plans for the future of the
IDE code. These plans involve making some relatively minor changes to the
current IDE core, mostly around moving some functionality up toward the
block layer. Once that's done, development on a new "IDE-TNG" driver would
begin. The existing IDE code at that point would be mostly frozen and thus
remain stable; new work would happen in the new, scary, dangerous "TNG"
driver. Support for older hardware would be removed from the TNG driver,
allowing a great deal of historical cruft to be cleaned out.
In retrospect, creating a new version of the IDE subsystem was the obvious
way to carry out a major reworking of this code. You simply can not have a
fundamental layer like IDE be unstable for months and expect to get a lot
of other work done. The previous IDE transition (from the old "hd" driver)
was handled in this manner. Had Marcin's work been done this way, he might
well still be at it now.
As it is, the window of opportunity for major IDE work in 2.5 has closed.
There is time for smaller cleanups and the addition of needed features, but
nobody has any appetite for anything that would seriously destabilize IDE
again this close to the freeze date.

Ingo Molnar's work to improve the kernel's support of threads was covered
here
last week. This week, Ingo has moved on
to the final part of a thread's life cycle: the
exit() call. It
turns out that the Linux
exit() implementation has some real
scalability problems, which are described and fixed in
this patch.
The cost of killing a process, it turns out, is proportional to the total
number of processes running. In situations where thousands of tasks are
running (and, remember, some threaded applications run thousands of
threads) the exit() call can become truly expensive.
Why is this happening? When a process exits, the kernel must "reparent"
all of its children to keep the process hierarchy consistent. This should
be a straightforward job, since each process keeps a list of its children
in the task_struct structure. Unfortunately, due to some
weirdness in how the ptrace() system call is handled, that list is
not sufficient. ptrace(), it seems, rearranges the process tree
so that the process being traced becomes a child of the process doing the
tracing. To find processes which have been temporarly relocated to a
"foster parent," the exit() system call must iterate over all
processes in the system. And that, of course, is where the scalability
problems come in.
Ingo's solution is simply to maintain a separate list of all processes
which are being debugged with ptrace() at any given time. That
list will generally be quite short. When a process exits, it is now
necessary to look at its list of children and the ptrace list, but
at no other processes. No more scalability problems.

Oliver Xymoron posted
a set of /dev/random
patches this week, introducing them with:
I've done an analysis of entropy collection and accounting in
current Linux kernels and founds some major weaknesses and bugs. As
entropy accounting is only one part of the security of the random
number device, it's unlikely that these flaws are compromisable,
nonetheless it makes sense to fix them.
Entropy, of course, can be thought of as the amount of random data the
kernel currently has available for the creation of random numbers. The
entropy pool is filled by looking at (hopefully) random events as seen by
the processor - such as the timing of device interrupts. Oliver's claim is
that the kernel is vastly overestimating the amount of entropy it is
accumulating, and thus handing out numbers that are not as random as
expected.
Some of the trouble comes from over-optimistic assumptions of the amount of
randomness really contained in interrupt timings. Simply put, the
resolution of interrupt timing is not what the kernel thinks it is. Oliver
also claims that interrupt timing is often observable or controllable by
hostile users. The timing of network packets has long been considered
suspect for this very reason; Oliver says that disk timing is subject to
the same sort of manipulation. Oliver has also pointed out a bug in the
way timing samples are merged into the entropy pool.
Finally, Oliver claims:
Worst of all, the accounting of entropy transfers between the
primary and secondary pools has been broken for quite some time and
produces thousands of bits of entropy out of thin air.
Interestingly, this last one may not be a real bug - read Ted Ts'o's explanation of why things are done
this way for the details. Generating random numbers that are resistant to
guessing is a difficult task.
Oliver's fixes have the result of greatly reducing the amount of entropy
available to the system, and thus the number of random numbers that can be
obtained from /dev/random. Linus doesn't like this aspect of the patch; he fears
that making /dev/random difficult to use will just cause people to
not use it.
Randomness is like security: if you make it too hard to use, then
you're shooting yourself in the foot, since people end up unable to
practically use it.
If /dev/random can not obtain enough entropy to be useful, says
Linus, it's probably better to just get rid of it altogether.
This discussion has reached no real resolution as of this writing, and the
entropy patches have not been merged. Some sort of fix will likely go in
at some point, once a compromise between "proper" entropy accounting and
usefulness has been reached.

"
Bogofilter is a Bayesian spam filter. In its normal mode of operation, it takes an email message or other text on standard input, does a statistical check against lists of "good" and "bad" words, and returns a status code indicating whether or not the message is spam. Bogofilter is designed with fast algorithms (including the Judy fast-associative-array technique), coded directly in C, and tuned for speed, so it can be used for production by sites that process a lot of mail."

"
A growing number of enterprise projects today call for a reliable method of binding Java objects to relational data -- and doing so across a multitude of relational databases. Unfortunately (as many of us have learned the hard way) in-house solutions are painful to build and even harder to maintain and grow over the long term. In this article, Bruce Snyder introduces you to the basics of working with Castor JDO, an open source data-binding framework that just happens to be based on 100 percent pure Java technology."

As is often the case, however, reaction to a new W3C specification, even a very early draft, exposed a venerable, enduring fault line in the XML world, namely, the split between XML users and XML core developers. In this case, we'll let the former be represented by the weblogging community, the latter by the XML-DEV list. Of course, this division is mostly a fiction, a little heuristic I'm using to make a larger point, but it's not entirely divorced from reality."

Convention, is up at the O'Reilly Network. "
In 1774, free culture
was born. In a case called Donaldson v. Beckett in the House of Lords in
England, free culture was made because copyright was stopped. In 1710,
the statute had said that copyright should be for a limited term of just
14 years. But in the 1740s, when Scottish publishers started reprinting
classics (you gotta' love the Scots), the London publishers said "Stop!"
They said, "Copyright is forever!" Sonny Bono said "Copyright should be
forever minus a day," but the London publishers said "Copyright is

Ultimately, this is probably all for the

Meeting nine times since kickoff in March, the Embedded Linux Consortium's Core Platform Working Group has achieved consensus on a strawman specification. The document will soon circulate for comment among member companies under the organization's intellectual property rules. This cycle will enable the group to build a completed core platform specification for the global embedded Linux community by year's end. A difficult but worthy goal, the Core Platform is expected to bring order to the market by reducing concerns and silencing competitive disinformation about operating system fragmentation and support."

Brian Finley
examines how corporate involvment in open source development has
changed things. "
Now the individuals working on a project are
doing it because they're told to, they're adding the features that
they're paid to add, and corporations are providing direction to the
developers instead of the individuals being self directing. Sure the
individuals have a certain degree of autonomy, but they must now work
within the scope of the "corporate good" instead of being focused on what
they think would be fun or on what they need to get their own job
done."

This article
on Tech Web claims that Linux may make it onto corporate desktops by
accident.
"
With so many companies lining up behind Linux enterprise solutions, the top-down theory that the open-source operating system might gain a piece of the corporate desktop market by being a server OS has some merit. Red Hat and UnitedLinux are the two organizations most likely to deliver such a version. But it'll be the big guns of IBM, Sun, Oracle, HP, Dell, and others whose increasingly Linux-based missions could literally push Linux onto the desktop almost as an afterthought."

Sun cites the fact that Linux has been growing faster on the desktop than in the server market as a primary reason that Sun plans to focus attention on the client side.

Sun will be able to shove nearly two

this proves you don't need Microsoft Windows to do your work, although
how Linux would be different from Sun's Solaris OS in powering such a
project, I really don't understand."

A focus on security is necessary, but can the
government and the Free Software and Open Source communities agree on
what that means? For the first time since the September 11th attacks,
one of the foremost computer security conventions took place: BlackHat
2002 in Las Vegas, Nevada. The American government embraced the occasion
as an opportunity to show the new direction they want to take for dealing
with security in cyberspace. Their new approach involves cooperation with
the industry, because the next major strike of terrorism very well could
be through cyberspace. And any attack on our society could be
severe. Fortunately, a lot of progress is being made in the field of
security, and a lot of that innovation is coming from the Open Source and
Free Software communities. When it comes to issues of security, however,
many governments have yet to find a good way to deal with free and
open-source software."

Hat Linux 7.2 only by different RPM package manager versions and
installer functions. Now that Raleigh, North Carolina-based Red Hat is

Dell, Hewlett-Packard and IBM partner with one or more OS distributors for kernel integration and support. Sun's limitation in using a version of Red Hat's Linux will likely prevent it from capitalizing on performance enhancements in enterprise applications and database management offered by Red Hat's Advanced Server--drawn from partnerships with Oracle and other ISVs. However, this limitation reflects Sun's plan to target edge-server applications based on LAMP (Linux, Apache, MySQL and PHP) and Sun One."

According to
this article in the Seattle Times,
Amazon.com has saved millions of dollars by switching to Linux.
"
Amazon.com switched nearly its entire computer
network to the freely shared Linux operating system not because of politics
but because it is helping the company grow and cut costs, Amazon's engineering chief said yesterday.
"We wanted the best tool for the task," said Jacob Levanon, director of
systems engineering at the Seattle-based Internet retailer.
Amazon has become a poster child for the progress Linux is making in
large-enterprise computing since the Web giant began using Linux to run 92
percent of its network computers last September."

According to News.com, Verizon
has switched
its programmers to Linux, and is saving bundles of cash as a result.
"
Telecommunications company Verizon Communications saved $6 million in equipment costs by moving its programmers to Linux computers, the company said Wednesday.
The company cut costs by replacing programmers' Unix and Windows workstations with Linux systems that run OpenOffice instead of Microsoft Office, said George Hughes, a Verizon executive overseeing the work. The average desktop cost went from $22,000 to $3,000 per developer, he said in a talk at the LinuxWorld Conference and Expo."

Linux receives some
mainstream press coverage from MSN.
"
Whatever happened to Linux on the desktop? Once upon a time the open, free operating system held a philosophical magnetism that promised to bring down Microsoft. But its reliability and low cost count for nothing at the PC coalface, where Windows rules.
It's different in corporate-land. Linux has had a dream run, its acceptance accelerated with support from heavyweights such as IBM and Hewlett-Packard. These companies want Linux to power their back-end servers, but when it comes to the PC, familiarity is more important than cost, and few are familiar with Linux."

Dear LWN readers,
There has been much discussion on the net - and particularly within the
free software / open source community on the issue of Reasonable and
Non-discriminatory Licenses. It has been pointed out that these
Licenses are discriminatory when it comes to free software. I also
believe that they are more discriminatory to smaller software publishers
than they are to the large ones. Especially the ones that are large
enough to have an arsenal of patents that they can use to manipulate
better arrangements with the holder in question.
I have a suggestion of what I would call a truly nondiscriminatory
license: Let's base it not on dollars or dollars per unit but on a
percentage of profit. For example if a new protocol were to be
developed to serve WWW pages and it became so prolific that all of the
major WWW servers (IIS, iPlanet, Apache, AOL, etc.) needed to
incorporate it to stay competitive then they should all be able to
license it in a way that made since to their business plan: whether
motivated by profit or not. If all of the WWW servers were forced to
license it for say 2.5% of their net sales then it would work out.
Apache is free. Two and a half percent of nothing is nothing. Problem
solved. Even AOL would score under this proposal as I believe that they
made the source code for their WWW server open source long ago. However
companies like Micro$oft - who charge lots of $$$ for their software -
would have to pay 2.5% of that some to the patent holder of said
protocol.
On the same note suppose someone developed NaI-HTML (New and Improved
HTML), patented it, and licensed it using this new RAND License.
Mozilla would obviously be able to use it for free (they charge nothing
for their software). Opera would be able to include it in the free
version of their software but may have to pay a small percent to include
it in their commercial version (or should I say
commercial/advertisement-free version) because they charge for it. The
tricky part would be Micro$oft's IE. If on the one hand it is solely
contained in IE and IE is given away for free I suppose that they would
be able to not pay. But, on the other hand if they embed the protocol
in Windows, so their other applications can understand it, then it
becomes part of a non-free system and they should have to pay. If they
chose to add the functionality to the Office suite then they would for
sure have to pay for it.
The tricky part is something like Mandrake distributing Mozilla: they
do charge for Mandrake but not for Mozilla; should they have to pay for
including a free program that uses the RAND protocol in their non-free
distribution? What about the people that download the ISO off off the
Internet and don't pay them anything for that - surely Mandrake cannot
afford to pay the RAND fee in that case.
Micro$oft is documenting many protocols at this very moment in its
attempt to comply with its anti-trust settlement. Further they are
trying to claim that by using a (current) RAND proposal that their
protocols are open to everyone. We, in the open source community,
understand that we are being discriminated against but we need a way to
articulate that point to Judge Colleen Kollar-Kotelly and others that
have the political power to affect change. Especially to organizations
such as the W3C who are getting stuck in the middle of a bad situation
by overpaid patent litigators.
Regards,
Tres Melton
P.S. This, by no means, means that I agree with the prospect of
patenting software. This is just an idea that would make it taste a
little bit less bitter.

Hi Declan,
I think that your article is of the same type that a German would have
written when Nazi's had started. Yes we know that Prof. Felton would not
have been prosecuted, but you know if the present trend continues for
another 10 years, the then Prof. Felton will not be given any warning and
would be prosecuted when presenting the paper and then he will go to
Jail. You think things are not that bad, only Russian employees are getting
Jailed. You will say that Skylarov broke the law, but no his company broke
the law. Do you think if you were a scientist for a brewing company, and
that company tried to sell the brew into some country where its prohibited,
and you happen to be in that country, should you be jailed. Skylarov was
just giving a presentation, like Felton would have been giving a
presentation. Ofcourse, if we take the German and Nazi example he was just
a jew, they won't do that to a German right.
I think your profession is also under the firing line. But you think that
you would be able to recognize a gun held to your head, right.
I think at the end of the article you get to the point of understanding
that this just a point in the battle and of course the proponents of DMCA
would much rather have Prof. Felton in jail. They just know that its not
possible with the current state of legislation. They will much rather wait
till they get to the next 10 steps.
I think Orwell's 1984 is coming, it would just be delayed some 25-30 years.
thanks,
-anand

(1) a single study does not a trend make

Good choice of industries. European banks use it, and Korean car plants. (-:

We should be wary of vendors hyping _anything_ as the next great technology.
Remember the extreme agony (multiple tries, multiple faux pas, and several
times as many servers for the same job) Microsoft themselves went through to
get Hotmail off the ground on Windows instead of FreeBSD? Think back further:
do you remember a program called `The Last One?'
Linux isn't the _next_ great enterprise-wide technology, it is the _current_
great enterprise technology. 95% of the tools you need exist now, are being
used in worldwide enterprises, and - as has been said in many places - are
getting better faster than anything else around them.
My little corner of the market is already to busy for me to deal with, the big
problem is to get enough ex-Windows people up to speed on Linux to cope with
the stampede.
Oracle have just realised that they're undermined, Sun is panicking because
they're a bit brighter than Oracle and really have seen the writing on the
wall, SCO have essentially vanished from the map (less than 12 months between
`Linux is a fad, ignore it' to being bought out by a Linux company), and the
screams and thrashing from Microsoft are kind of self-evident.
SGI jumped on the bandwagon early, although they still seem to be unsure how
to ride it. Gartner don't seem to know what to make of it. Every new report
seems to work against the last.
Cheers; Leon
