Trip to M�xico City

by Miguel de Icaza

I will be talking to some Novell customers in Mexico City about Novell Linux initiatives and some of the Novell offerings on Thursday September 20th, if you want to come, register here.

A Nation Divided

I found this link from Jon Udell's blog: Valdis Krebs has graphed the books purchased in online retailers and has come up with a pretty interesting view of the nation based on the book purchasing patterns.

It begins in 2003 continues in early 2004 and there is a recent update

Atsushi Enomoto on the Move

Super-hacker Atsushi Enomoto is on the move. He will be at the XMLOpen conference in the UK representing the Mono team, and later will land in Boston for couple of weeks to do some local hacking and consume lobster sushi.

Evolution 2.0 is out

Evolution 2.0 has been released.

Shame about the shortcut bar being gone, I never use the folder list, I have my life organized using shortcut bars.

MD5 security: great blog entry

by Miguel de Icaza

Sebastien has posted his thoughts on the MD5 vulnerability. Check it out!

Robert Cringely

I always find Robert Cringely engaging on his articles, and his last installment follows this tradition. Some would say its nothing short of insanely great.

Anyways, a couple of thoughts:

  • 50,000 or so geeks over at Microsoft spend some portion of their time thinking `How can we defeat/block Linux' and they come up with some pretty crazy ideas. In this installment Robert makes the point about the new USB system, but this is just one angle.

    It is clear from Chris Anderson's last post that it is an ongoing strategy to come up with schemes that will lock Linux out (even if they are highly inadequate for the world where scams are the rule of the day).

    Avalon's feature set is one of these creative things they come up with. I am convinced that they see Avalon as the tool that will replace the Web (the marketing folks will step in and claim that they `augment the user experience').

  • The software industry like no other one has a tremendous flexibility to create completely new models and abstractions, roll out prototypes and such.

    Maybe we are reaching a point where we need government regulations on the software industry or in some of its components. An explicit acknowledgment of Linux and open source players as an important player in consumer choice.

    Ah, not only had I suggested that when Slashdot posts a link to the MS lobbying efforts.

Speaking of augmenting the user experience. It is clear that plenty of work can be done today to augment the user experience of the web: GMail and Google Local services is leading the pack in smooth user interfaces. Everyone is raving about the keyboard navigation, the clean look and the good interaction of GMail, while am delighted to see the clever hacks to explore maps without doing page reloads.

And finally there is A9 who also sports a great user interface on the Web.

Firefox reaches one million downloads

Firefox reached one million downloads ahead of schedule. Congratulations to the Mozilla hackers!

Tomboy: the latest hack from Alex

by Miguel de Icaza

Alex has released into the world his tomboy software. Check it out. Am addicted to it.

Kerry Followup

Another reason to vote for Kerry: to avoid more de-regulation.

Been enjoying reading Stiglitz's new book: The Roaring Nineties.

Posted on 18 Sep 2004

Follow up to John and Todd

by Miguel de Icaza

John list of reasons to vote for Kerry was zero, so I figured I could cook up a few interesting links:

  • Chomsky said: "Kerry is sometimes described as 'Bush-lite', which is not inaccurate. But despite the limited differences both domestically and internationally, there are differences. In a system of immense power, small differences can translate into large outcomes."
  • For an outsider like me, it seems interesting that Democrats can fix the deficit, while republicans like to get in debt, nice graph.
  • Military spending will not likely make the US more secure, see Zinn. Am not an American, but am living in the USA, so I care about my security.
  • Kerry's position on greenhouse-gas emisions.
  • Kerry's non-nuclear proliferation.
  • Kerry's position to embrace science instead of ideology. Contrast with the current administration distorted research.
  • Kerry's economic policies were endorsed by ten nobel prize winners. I guess its simple to have better policies than Bush, as Nobel economic winer described the current policies: `The worst in 200 years'.
  • MoveOn has a few ads. My favorite: the fisherman (Richard Dove).
  • Woody Allen thinks that voting for Bush for him would be tragic, extremely tragic.

I guess am biased being the son of a scientist and all that.

New Chomksy

A new piece from Chomsky.

I also found his blog. Wonder if Chomsky uses Emacs being from MIT. I have always wondered how approachable Chomsky would be to have dinner with my friends. Anyone have his email address?

Gnome Updates

A new publication: Gnome Journal to keep up-to-date on interesting bits from the Gnome world.

Gnome 2.8 was released: fancier, simpler, cleaner and more hip than ever.

I had dinner with the Fluendo guys in Barcelona last week at Thomas' place days after they had released their Theora Java applet. The quality is very good, and the best thing is: you do not need to install any software on any machine to watch live video streams from Theora servers. They will be happy to sell you a streaming server.

The Gnome Summit announced its dates; this year in Boston will be held in the Stata Center in MIT, the new gorgeous buliding across the street from the Cambridge Novell offices where we work from: Mark your claendars.

Jeff's company launched their new distribution: Ubuntu. Not only they picked a great name for their company, but they are adding timed releases to Debian, I would say the major problem for Debian's adoption (please do not send me email saying `just use sid/whatever' or `Debian testing is great for me').

Evolution 2.0 is finally out according to the state page. But I can not find the official announcement. An overview of some of the new features is here

Errors and Warnings

When I started using C# on the early preview days of .NET, one of the first things I noticed is that the compiler did quite a lot of work to produce helpful error messages.

While implementing MCS, we noticed that it went beyond the obvious internal checks of the compiler: the MS C# team actively had to add extra work to produce a more meaningful error. This is in addition to C#'s definite assignment requirements which by itself catch plenty of errors that are commonly introduced in C.

Recently Marek Safar has been on a quest to refine our error and warnings to produce as many as the MS compiler does and to fine tune our reports. We are not there yet: today we catch 617 errors/warnings, we fail to report 18, and we report differently in 136 cases.

The parsing errors are the most difficult to cope with our compiler as we used Yacc to build the parser and the parser recovery is a lot harder than if you do your own top-down parser (something that we might do in the future).

Being Fabulous

I did a presentation on Mono last week at the Universidad Oberta de Catalunya, here is the: video.

I was exhausted when I did the presentation, having slept only four hours for the past fourty-eight due to the jetlag, the dinner following up was excellent, I had a chance to talk to a few folks afterwards.

Back from Barcelona

by Miguel de Icaza

Noticed that Matthew MacLaurin from MS research weight in on Nat's work on the dashboard, WinFS and metadata.

Paco has posted a nice update for those who want to use Gtk# on Windows: simple installers and integration into Visual Studio as well as videos to see for yourself how to use it.

Nat's keynote presentation this morning was excellent: plenty of content packed in the fifteen minutes they had allocated, and they showed some Groupwise integration, F-Spot and collaboration features using iFolder.

The best feature of iFolder in my opinion? Being able to share the folder with myself in different computers: my laptop, my Windows box at work, my Mac at work and my two computers at home. The idea is simple: now all the data gets replicated and I no longer have to worry about which machine has the latest version of a draft.

Massimiliano explains his SSAPRE implementation for Mono. Massi has been working on implementing the large optimizations for the Mono JIT engine.

Gonzalo and Ben have been working on making Mono's ASP.NET implementation scale and perform better. The upcoming 1.1.1 release will contain all the goodies. Get ready to be impressed.


I will be in Mexico City on Tuesday. To reach me, call my US cell phone number, I doubt my local phone works anymore.

Avalon part 2

by Miguel de Icaza

Chris Anderson from the Avalon team replied to some of my points that I made last week

First, let me stress again that I think that the guys over at the Avalon team are doing some fantastic work and probably have had to make some hard decisions and have a lot on their plate.

Cris, As I said in my previous post, if Avalon really takes off, we might look into bringing that API to Mono as well.

My concerns stem from the fact that we do not want to waste our time with dead-end APIs as we are vastly under-resourced, so we must choose carefully. With that in mind, and keeping in mind my bias.

I agree that solving the low-tech attacks effectively with software is probably a research subject. And I appreciate that you guys are putting a lot effort on the security infrastructure for WinFX, Avalon and .NET but it still falls short: it will not resist the low-tech attack today.

Bruce Schneier has a good introduction to attack trees. The core is that in any system that is to be secured an attacker only needs to choose the weakest link. In this case, Avalon's ClickOnce just seems like a disaster waiting to happen. Imagine Outlook viruses gone wild.

Solving this is extremely simple, the answer is well known: do not allow ClickOnce-like technologies.

My guess is that the problem is that this goes against the fundamental reason for the existence of Avalon.

Joel's latest piece has some good points on the role of software in societies. It seem that engineering organizations are too much in contact with the technical details of how to make things happen, without looking at where and how the software is going to be consumed.

Certain things in the Gnome world have been hard explicitly to avoid problems of this nature (the never-shipped and luckily-defunct executable-mime-type handler is one example).


Anyways, my problem is that it seems that Avalon is trying to do too much too soon. It seems to be following the over-designed footsteps of Java's Swing: it avoids the over model-view-controller-itis, but it introduces its own pains and has the elements of a second system

The surface area is just of gargantuan proportions, sure, if you are dealing with a `Button' you will be fine. But hey, it was relatively simple to build buttons with Motif and Swing too.

You are right that it is unfair to comment on a product that is not even beta, but if you guys are shipping in 2006, I do not see a lot of room to maneuver there. I can only hope I am wrong.

Tk and XView are nice examples toolkits that hide the complexity from the user each on their own ways. These toolkits encapsulated the complexity and exposed only the basics to the user: they provided fairly high-level building blocks and the rest was tucked-in behind the scenes. On the other side, we have things like Avalon where the implementation details transpire at every level: not only is the developer going to use the high-level building blocks, but he will be exposed and will face the internals.

Am not arguing that it is necessarily bad, but it is easier to expose as little as possible and add features on an as-needed-basis than it is to come up with a large framework and maintain every implementation decision made today.

By exposing as little as possible you have a choice when it comes to architecting the internals, and most importantly to re-architect the internals in the future if you must. A clean separate between the exposed API and its implementation. But Avalon does not have this luxury: the API is the implementation and the API transpires very much of the implementation (mind you, this is very convenient for people interested in re-implementing it, while tying their hands to an existing design).

I read with interest the various justifications for not following the standards just when Avalon was coming out, I wont argue about the merits of the CSS one, but the case for not using SVG is particularly poor: `not using pascal casing', `not using full english words'?

It can only make sense in a world of only-Microsoft technologies, but even there, you are shooting yourself in the foot: collaboration with others might be initially difficult, but it has always paid off in nature.

Collaboration of Microsoft with competitors tends to be difficult. Maybe there are ways we can improve this.

As for missing features, there are ways of driving the standards forward. For example the whatwg group is finally moving the web forward again.

In any case, thanks for listening Chris, and lets hope that you guys can improve Avalon, but in the meantime some folks are considering the options, Joel has two good articles: API war and his call to arms to improve the Web with some followups. Update: Fixed a few typos.

Mono Updates

Sebastien has posted an update on CAS.

Our XQuery implementation was born on August 20. Atsushi has posted an update on System.XML 2. You can also see his prototype to call CIL from XQuery.

Debating trip to Redmond

Due to some other commitments it seems unwise to attend the TG2/TG3 ECMA meetings in Redmon on the week of the 20th.

Am wondering if I should fly in on Sunday to attend the Tuesday meeting. If there are people from Microsoft interested in meeting on Sunday for dinner and Monday (nothing formal, just chilling out and debating software things). That might make for two useful days: one ECMA and one of chilling out.

Thoughts? miguel at novell dot com is the address.

Have to make a decision on the next 48 hours.

Another Molly Ivins Gem

Molly Ivins can write very well.

Greg Palast on Choice Point

Greg Palast on Choice Point and the DNA database of every citizen:

These guys are in the Fear Industry. Secret danger lurks everywhere. Al Qaeda's just the tip of the iceberg. What about the pizza delivery boy? ChoicePoint hunted through a sampling of them and announced that 25 percent had only recently come out of prison. "What pizza do you like?" asks CEO Smith. "At what price? Are you willing to take the risk?..."

Oh my god! Good thing I get my Pizza from the frozen section at the minimart. I feel safer now.

On Resolution

by Miguel de Icaza

I have been using a laptop with 1400x1050 for more than a year, probably two years. Recently I have been considering getting something more hip, to go with my hip nature. Something like the IBM X40.

The only problem I have is that anything below 1400x1050 now feels to me like this:

Associated Press: Beating the last year record of 375 billion dollars, this year the projected deficit is going to be 422 billion.

Taylor just sent this note:

	Budget Deficit  $442,000,000,000
	                      divided by
	Workers              141,700,000 (Census Bureau)
	Equals                     $3119 per worker
	I hope you all are ready to work extra hard next year.
	 Flak Jackets don't grow on trees.

Economic girlie men with a twist.

Update 2: Am sorry for updating this so many times, but I could not help but make a reflection. The `do not be a girlie man' defense of economic and tax policies sounds as idiotic to me as the defense of the internet boom business models. I can not help but think back at how a few people warned of the coming catastrophe and people laughed at those who were wondering where the profits were and how those things would be sustained.

It seems that the current economic and tax policies are rooted not on careful economic research but in punch lines. That bubble is going to burst.


I will be going to Barcelona on Saturday for the Novell Brainshare conference.

Jordi has also organized a public Mono/Gnome presentation at the University Oberta de Catalunya on Tuesday (September 14th).

Update: The location is: UOC, Avgda. Drassanes, 3-5, Barcelona at 7pm. I will try to drag Nat Friedman along.

Nat in Barcelona last year.

Peace Activist Detained

Guardian: On Sunday, the military placed Ms Fahima in detention without trial using a law applied to thousands of Palestinians over the past four years of intifada but rarely to Israelis.
