What do you think?

March 30, 2007 14:48:05.954

I'm interested in some feedback from people - specifically, people who have dealt with Cincom (whether it was the Smalltalk group or not). I'd like you to tell me two things:

  • What have you liked most about your interactions with Cincom?
  • What have you liked least about your interactions with Cincom?

Those are wide open questions - the answers could be on any aspect of Cincom you've dealt with. Feel free to post comments here, or send me email. I won't post email comments unless you specifically ask me to.

Network Management in Smalltalk

March 30, 2007 9:17:21.154

IBM is looking for a Smalltalker (VisualWorks) to help build Proviso:

Join the team developing Proviso. Proviso is a highly distributed and scalable stream processing platform for collecting, processing and persisting large volumes of network performance data. Our largest customers manage many terabytes of network performance data. Proviso was recently acquired by IBM Tivoli as part of an initiative to expand its presence in the telecommunications industry and become the leading provider of network management software.

Looks like the slot in in Lowell, MA.

Smalltalk Tutorial Outputs

March 30, 2007 9:09:37.300

I should mention the "outputs" of the Smalltalk tutorial that I did last Sunday. The SPA conference (and Ot before it) has always been big on session outputs - the idea being that other people should be able to benefit even if they didn't/couldn't attend the session.

With that in mind, the tutorial page on the Wiki is here.

To summarize the summary :)

Web 2.0 and Open Source: Implications

March 29, 2007 13:36:36.340

Dare Obasanjo made a provocative point yesterday in a post titled "Open Source is Dead". His premise? That services like Twitter (and Flickr, and other "Web 2.0" things) create vendor lock-in differently - it's the community that matters most. So what if I have the source for a Twitter clone: can I create a community around my open alternative that somehow grabs people from Twitter? It's an interesting essay, and rather than try to summarize it, I'll recommend that you head on over there and read it.

Whistling Past the Graveyard, Defined

March 29, 2007 1:52:24.110

Filed under "whistling past the graveyard", David Hughes, a senior VP at the RIAA:

"The RIAA is well-aware that they are becoming irrelevant. They are also aware that nobody likes them, but they don't care about that. Someone also brought up the fact that the RIAA was recently voted as being the "worst company in America", to which David responded with some laughs and a quip about how they've been "beating Exxon-Mobil for years" in that arena."

But hey - we'll just keep suing people - that's got to provide positive PR.

Not so Much...

March 29, 2007 1:42:25.507

Daver Winer, on the latest revelations from the Kathy Sierra mess:

Next time -- think before you trash someone, no matter how much you dislike them, especially because you dislike them. It takes courage to stand up to a mob, but that is the best of what it means to be an American.

Small problem: The morons who set up meankids.com knew where that was going to go. Or worse, if they didn't know, they've been living in a cultural deprivation cave for their entire lives. If you're old enough to remember the early "social media" - BBS systems, USENET, and forums - then you darn well knew what was going to come out of a site that encouraged anonymous stuff.

Doesn't mean the people who set it up intended to see death threats tossed around, no. However - if they thought anything valuable was going to come out of such a venture after watching online behavior over the last two decades, then there's something deeply, deeply disconnected about them.

Insight on MS - and in general

March 29, 2007 1:26:47.163

This post from an anonymous MS insider hits a lot of good points on what's wrong (and right) with Microsoft - but more importantly, it makes points that many companies would do well to listen to. Take this, for instance - which is very much in line with things Laura Ries has written:

Stop fighting major wars on multiple fronts simultaneously. It is simply ridiculous for current management to assume that MSFT can fight the biggest and best companies on earth, across a dozen or more battlegrounds, and still hope to prevail. Just take a look at some of the folks MSFT is going up against: SONY (and Nintendo) in gaming, Nokia and many others in mobile, GOOG and YHOO in Search, Everyone from Alcatel to Siemens in IPTV, IBM/Oracle/SAP (and smaller players Salesforce.com. Rightnow, etc.) in ERP and CRM, IBM/Adobe/FOSS in middleware and development, AAPL and most of MSFT's former partners in mobile media, AAPL and GNU/Linux in Operating Systems, and FOSS in personal productivity. Worse, these battles are spreading MSFT too thin, and leaving its core cash cows increasingly vulnerable (would Vista have taken 5 years to develop if management hadn't been distracted with a dozen other battles?). MSFT needs to prioritize the current list down to something more realistic, while ensuring that the appropriate vigilance is maintained on the crown jewels. As a start, any new battle should require them to give up an existing one. Notice how that NEVER happens and they're always additive instead?

In the small, the new roadmap we just published takes that thinking into account: we (Cincom Smalltalk) simply cannot pretend that we can keep up with every development trend in the industry - while we aren't tiny, we certainly aren't as big as IBM, Sun, or Microsoft.

It's something that every company needs to keep in mind though: MS might dwarf a lot of outfits, but even they can be spread too thin and be fighting too many battles. If you're a product manager, as I am, that paragraph I quoted above provides a lot of food for thought.

There's no reason, it's just the rules

March 29, 2007 1:12:05.699

I suppose it's reassuring to know that the TSA is not the sole repository of stupid rules that have no impact on actual security (TM). This morning, I had to go through security here at Heathrow - so I get to the outer line, and they tell me that I can't have more than one bag (I have my laptop bag and a new bag I got as swag at SPA 2007). However - and here's the stupid part - it was fine so long as I turned one of the bags sideways and stuck it inside the other one (mind you, a good fourth of it was sticking out at that point).

So far as "the rules" go, I was no A-OK. Of course, I got down to the actual scanners, and had to separate everything for the machines - but that was fine, since the only ones concerned with the "one bag" rule were the gatekeepers. Once inside, you could take everything back apart and have as many bags as you liked.

The bizarre thing is that someone thinks this serves a purpose.

Scoping Features

March 28, 2007 12:55:26.037

There was a very good session this morning on scoping, which involved a game to get the idea across. We set up teams of three, and each of us got money, product cards, and feature cards, along with marketing info. Our task - decide which products to ship with which features, given the constraints of reuse vs. one off features (more cost for reuse) and the monetary limit. Here's a picture I took of the board after round 2:

In round one, we didn't spot a way to tradeoff one of our dollars, and decided to ship only 2 of 3 possible products - which is why we tied for second in round two: we were just too far behind after that mistake. It was fun though, and it put the whole product marketing/management decision process "in my face" in a very good way. Food for thought.

A Twitter Business Case?

March 28, 2007 9:21:48.324

Via TechCrunch, I see that a way for Twitter to make money does in fact exist:

Currently, it costs a lot of money to launch a start-up in the SMS/mobile space — you have to license a shortcode monthly ($500-$1000/mo), pay a SMS gateway provider, and then pay anywhere from $0.03 - $0.05 per inbound or outbound text message. It adds up. But now, if a start-up chooses to use Twitter as a command line to their web service, it’s free (until Twitter starts charging for it).

So right now, Twitter could be in "viral" mode, getting people hooked. Later, they could start charging a nominal fee for the service. Hmm...

Authenticated RSS feeds

Jon Udell notes that authenticated RSS is hard to do, and ended up picking up RSSBandit to solve his problem:

Today I created a private blog site that is, Internet-accessible but SSL-and-password-protected and realized that there was no easy way for most people to subscribe to it. Even if the popular cloud-based readers like Bloglines and Google Reader supported authenticated feeds, I wouldn't want to let them use my credentials to impersonate me.

BottomFeeder has supported Digest and Basic Auth protected feeds (with or without SSL) for years now :)

API Design as if Unit Testing Mattered

March 27, 2007 5:51:06.923

I wasn't awake enough to take notes on Brian Marick's keynote, but I should have - it was a great talk. In any event, I'm attending Michael Feather's talk on API design. He's starting with a common problem developers have: say you want to fetch mail in code. You then have to dig through the API documentation (or in VW, the PDF docs) to figure out how to use the mail code. Interestingly enough, raw API doc isn't that useful without accompanying "how to" type doc. IMHO, what you really want in this case is example code - the API documentation doesn't help you initially (although it will help you down the road, when you want to do more. On the Smalltalk side, you then go browse code, but that works just as well - even though it's "politically incorrect" compared to massive API doc :) )

This particular example is of interest to me because I did screencasts on mail sending and receiving just last week - and I didn't have to create a new class just to figure that out. After perusing the example code in ours doc, I just tossed a few lines into a workspace and tried them out. Once I had that down, I just did the screencasts :). Ultimately, you do what I did in BottomFeeder - create a class that wraps mail sending (or receiving), and deal with your own API, and then have a simple place where the underlying vendor API is isolated and easy to manage.

So API Design: The art of creating interfaces that are useful to clients and extensible for future needs. Not all interfaces are APIs.

Unit Tests: They really do need to be isolated (i.e., not dependent on network communication, database results, etc).

API Development is hard work because:

  • APIs live forever
  • Meaning, Mistakes live forever
  • Early choices can close off future desires

Interesting comment next: Avoid Static Methods. I would have said that Sun simply screwed up, and didn't create real objects. If classes in Java were actual objects, this problem wouldn't exist. Heh - he also recommends against using Sealed, Final, and non-virtual. Again, those aren't features - they are bugs.

Here's a good piece of advice: write code that uses your own APIs. If it's too hard for you to use, then what will your clients think? As well - supply your tests to the end users (developers). There's no good reason not to.

A Pocket Definition of What's Wrong

March 27, 2007 5:10:30.176

Phil Windley, on this talk:

The basis for the talk is Seaside , a web framework for Smalltalk that Avi wrote several years ago. The problem with Seaside is you're not going to use it! There are a lot of interesting ideas in Seaside that people should know, so this tutorial is way of spreading the ideas outside of Smalltalk.

In a nutshell, there's what's wrong with the software industry. People see a fantastic technology, but insist on rewriting it (badly) in other languages because it's "politically correct" to do so. Productivity? Time Saving? ROI? Apparently irrelevant.

Wrong Answer

March 26, 2007 19:49:23.947

Scoble on the Kathy Sierra mess:

So, since she doesn’t feel safe. I’m going to stop blogging in support of Kathy, who I consider a friend and someone who’s voice would be dearly missed here. I’ll be back Monday.
The Internet culture is really disgusting. Today when I was on Justin.TV the kinds of things that people were discussing in the chat room there were just totally disgusting and over the top.

It's not specifically internet culture - we've seen this in email (and further back, on BBS systems) for years. People will say things in text that they would never say in person - because they feel like it isn't "personal". The answer isn't pulling back - it's more speech, more condemnation, more un-acceptance of bad behavior. If we want bad behavior to stop, we have to stand up to it. Pulling back only encourages it.

So here's my part of the disapproval: The people Kathy mentions in her post who were willing participants (active or passive) in this set of disgusting threats (including death threats) against Kathy - you should all be deeply ashamed of yourselves, and - at the very least - you should all offer personal apologies to her. Failure to do so will demonstrate one thing, and one thing only: that you have no character. I mean you, Jeneane Sessum, and you, Allen Herrel, and you, Chris Locke. I would hope that those three (and anyone else involved) get actively shunned until they publicly apologize. Maybe Scoble wants to withdraw and not call a spade a spade. That's not me.

Update: Sadly no - this blizzard of "Not Me!" doesn't count as an apology or explanation.

Creativity Workshop at SPA 2007

March 26, 2007 19:28:57.749

It's been a good day at SPA 2007 - I attended a Creativity workshop this morning, which was pretty neat. The idea was this: we got a problem statement, and then we did some brainstorming exercises to either find solutions or better understand the problem. Our group had a "Lotus Blosson" exercise:

  • Toss out an idea
  • Find eight related ideas and ring them around it
  • Then pick one or more of those, put them out, and repeat

We didn't find solutions, but we iterated towards understanding the problem. Here's a shot of one of the other groups, using lots of paper on another approach:

Earlier, we had a little exercise that went like this: Statements on a board, handouts with other statements. Find the ones that are "opposite" and tack them up:

So that was a fun session - I might well try some of the ideas out at work.

Java: Not the cool answer anymore

March 26, 2007 18:56:35.253

Phillip Greenspun explains that Java is fading from cool to passé:

In September 2003, I innocently posted Java is the SUV of programming languages? based on the fact that students in 6.171 who’d chosen to use Java were incapable of getting anything done. It created quite a stir in the comments and on Slashdot. This semester is the first time that we’ve taught 6.171 since then. Despite the fact that all the students are expert Java programmers, having used Java to build a big project in 6.170, none have chosen to use Java this semester. It is all Ruby on Rails, Microsoft .NET (C#), and a touch of Python.

Meanwhile, the Enterprisey folks - who are always years behind the curve - still think it's the end all, be all :)

Turning up the Heat on Agile Projects

March 26, 2007 12:29:21.958

This workshop is going to deal with how we deal with problems on a project - Joseph Pelrine and Ben Fuchs (tech and psychology). More information on this stuff on their website: http://www.cateams.com/index.php. Difficult Behaviors - from minor to bad:

  • estimate fudging
  • chronic lateness/under-performance
  • gossiping
  • negativity
  • harassment
  • vandalism
  • physical violence

For our purposes, "difficulty" is in the context of the team and the project. We can deal with the team or with the individual.

A nice metaphor for team state - compare to cooking:

  • Burning: Team in panic mode, chaos, ruination
  • Cooking - things mix properly, flavors come out, things progress
  • Medium Heat - things stagnate, don't mix - things break (meetings missed, bugs accumulate)
  • Low Heat - things congeal - "This is how we do things"
  • Off - solid, "This is how you must do things" (no discussion possible)

Periodically, you have to "turn the heat up", and then let things cool on their own (as the team self organizes). How do you turn the knobs?

  • Work Pressure (TimeBox vs. amount of work)
  • Diversity (age, gender, perspectives, ethnicity, etc)
  • Physical environment
  • Tools to slow down/and/or amplify team dynamics
  • And, of course, conflict

Dealing with conflict: Pre-Conventional (Police, Medical staff use these sorts of approaches)

  • Core Issues: Physical Safety
  • Metaphor: Conflict as a threat to survival
  • Model: Conflict management, de-escalation
  • Approach: Positive authority

Conventional (most professional situations)

  • Core Issues: Identity, Rank, Power
  • Metaphor: Conflict as a threat to identity
  • Model: Conflict Resolution
  • Approach: Mediation/Facilitation

Post-Conventional (teams/inter-personal, for instance)

  • Core Issues: Shared meaning
  • Metaphor: Conflict as opportunity
  • Model: Conflict transformation
  • Approach: Sense-making

Constructive conflict requires emotional maturity and an ability to be self reflective. The session included multiple exercises, and I can't really convey those here.

Interesting perspective: We look at things via OIC: Observation, Interpretation, Conclusion - where the latter two come from our own beliefs, biases (etc). Often times, we see things completely differently than the other person intended.

We wrapped up with a group exercise: one of the participants related an actual work problem, in order to generate some feedback. I'm not going to say anything about it, as we all agreed to keep all the people involved anonymous.

History? Who needs that?

March 26, 2007 11:38:12.883

James McGovern talks about outsourcing in India (et. al.), and makes a snap judgement based on an utter lack of historical awareness:

People are poor if they have to purchase their basic needs at high prices no matter how much income they make. Take the case of India. Because of cheap food and fibre being dumped by developed nations and lessened trade protections enacted by the government, farm prices in India are tumbling, which means that the country’s peasants are losing $26 billion U.S. each year.

So.... The migration of industries like textiles and heavy manufacturing from England to the US in the 19th century did long term damage to the US? Sheesh - I wish people had some base awareness of what's happened in the past before they started making sweeping generalizations.

Dave Thomas Keynote

March 26, 2007 9:32:50.934

I wanted to exercise, but I couldn't pass up the opportunity to hear Dave Thomas (Smalltalk Dave) give a talk. Dave is having a fun time offering to let us vote on which of his two presentations to give :) Heh - he's skipping the planned talk due to audience demand, and saying only that there are ways to introduce agile techniques into large organizations. Instead, we're going to take a look at where Dave thinks development is going in the next decade and a half.

Since leaving OTI, Dave has founded Bedarra Research Labs - he's looking to be able to do some development again, but current technology fads make him feel like he's had all his limbs hacked off. The problem: we're in an incredible complexity mess due to the badness of the current languages. This has generated a plethora of tools to try and compensate for that, but it only makes for a bigger pile. We have what Dave calls "Latent Technical Complexity".

Open SOurce from OS to Application allow every customer application to be "unique".

Why the latent complexity?

  • Objects, components, interfaces, AOP, WS*, SOA (etc, etc)
  • Enterprise Applications and the need for their customization
  • Integration is difficult.
  • Flagrant disregard for limited resources (Embedded Java, XML, SOAP)
  • "Linux works because it's basically BSD circa 1980"

Lessons:

  • KLOCS kill both performance and ability to evolve
  • A Better Algorithm is better than optimization

There's a real skills gap: "everyone" knows Java: "Certification is a statement that you aren't competent". If you want to be where the action is, it's in the domain (business) side, not the development side.

MDD: The Ideal. Then there's the OMG (Object Losers Group, heh). way: MDA, or UML all the way down. This gives you development and debugging at the level of the abstraction. Interestingly, UML isn't even fully defined.

Heh - you aren't getting the real flavor of this talk - Dave is a truly funny guy.

The challenges of next generation applications: Business Driven vs. Technology Driven.

  • Based on sound and deep understanding of the business
  • complexity mandates development driven by business experts - domain fusion, probablities and fuzzy reasons)
  • Support for high performance teams
  • First time applications vs. traditional processes improvement

Real time business:development in real-time, execution in real time. They have masses of data and event streams. Important point: Processors, memory, bandwidth, and storage are "free" - Amazon ECL and S3, for instance.

So going back to games: Not just the fun stuff of the graphics and physics. You also have data persistence and versioning. You have distributed processing, visual content editors, scripting and compiler technologies, and UI work.

Game updates happen at high speed, they are distributed, and state changes hit multiple other objects. So back to MDD: a natural way of expressing application requirements in a disciplined and well understood "language" which models some aspect of the domain.

We want to work in a high level, domain oriented language - which will allow us to specify the domain more easily. Ideally, the developers would work with a domain (not a software engineer) expert who is versed in computational modeling. This is really about DSL (Steve Kelly!) - Domain Specific Languages.

Back to the future: We want languages that encourage "think and try it" - not ones that favor "design code and test". There are lots of examples of end user programming: Spreadsheets, MatLab, QBE tools, visual languages like ProGraph, DabbleDB, etc. There are lots of important things that aren't being taught anymore:

  • Constraint Programming: ThingLab
  • Dynamic Object Programming: Smalltalk, CLOS
  • Logic Programming: Prolog
  • Reactive Programming: Erlang

He listed others - point being, "fad" training is what Universities do now. Language design challenges:

  • Expressiveness
  • Readable and Writeable
  • Strong specific vs. Strong generic (domain-wise)
  • Uniform access to data (i.e., LINQ)
  • Persistence
  • Supporting multiple domains
  • Supporting multiple paradigms

SPA 2007 Begins

March 26, 2007 3:13:48.480

It's the opening session of SPA 2007, here at Homerton College. It's a nice location - I like it better than last year's spot, the Robinson Centre. There are three sessions of interest to me this afternoon after the opening - I'm going to head on over to Joseph's session though, since we are adopting more of a Scrum-type approach to development on the Cincom Smalltalk team. Here's to a good week!

Sunday Sessions Wrap

March 25, 2007 16:40:19.578

The tutorial I gave this afternoon went fairly well - I had fifteen people and a lot of questions. It was fun to get in front of a group of non-Smalltalkers and show off the system again - and it also reminded me of how long it's been since I was a beginner (the beginner questions they had weren't anything like the beginner questions were back in the 90's, when I taught for ParcPlace. Oh, for anyone interested in what I covered: it was a shorter version of Smalltalk Daily - which you can watch in order here.

I got some more requests from CD's after the session as well, so word of mouth must have been ok :)

After things wrapped up at 7 PM, we headed down to the great room for a Google sponsored dinner:

Joseph Pelrine is here, so I took a picture of him chatting at a table - I also want to thank Joseph for his help during the tutorial today - he sat in and had some helpful and timely suggestions. Thanks!

So now I just have to sit back and enjoy the conference - and there are a number of good sessions that conflict tomorrow. Decisions, decisions...

Negative PR Horizon

March 25, 2007 6:02:01.675

Slashdot highlights some more of the RIAA's finest work:

"The latest target of the RIAA's ire is a 10-year-old girl in Oregon, who was 7 when the alleged infringement occurred, and whose disabled mother lives on Social Security. In Atlantic v. Andersen, an Oregon case that was widely reported in 2005 when the defendant counterclaimed against the RIAA under Oregon's RICO statute and other laws, the defendant's mother sought to limit the RIAA's deposition of the child to telephone or video-conference. The RIAA has refused, insisting on being able to grill the little girl in person. Here are court documents

I wonder how much caffeine the RIAA's PR staff needs to take in to stay ahead of the constant wave of negative PR Events generated by their lawyers?

The conference is starting today - I've got my talk in a couple of hours. Unlike the chilly drizzle we had yesterday, it's nice out today: I took a picture of the central quad here at Homerton:

Looks like it'll be a good day to teach Smalltalk!

Saving Newspapers

March 25, 2007 5:36:27.621

Doc Searls has a number of suggestions for newspaper owners - sadly, most of them still aren't ready to hear any of them - even though the wolf is at the door.

Scoble has related thoughts on this here - and he's not pulling any punches:

The industry has NOT invested in its future.

It is reaping the rewards of that.

How many future journalists are being trained for the online world?

I can tell you how many: zero. When I talked with students back then about half thought they were going to work in newspapers.

I told them they were smoking crack.

Harsh, but not wrong.

Industry Misinterpretations 28: Twittering

March 25, 2007 3:41:03.216

We had some timing issues this week - David Buck and I recorded at 5:30 yesterday afternoon, without Michael. Michael woke up an hour later and then he and I recorded a session. I'm posting the latter session as this week's episode - only so that Michael can make his announcement himself.

Michael and I spoke about web development using Javascript/Ajax, and then moved on to Twitter and our recent work on Swallow. We also touched briefly on some of the emails we've been receiving. I'll be posting the session I recorded with David next week - due to an equipment problem I had partway through that, it's a tougher editing job :)

Some ideas for Swallow

WKRP going to DVD

March 24, 2007 18:36:24.223

This will make my friend Mike happy - WKRP's 1st season is hitting DVD. He had mentioned that the holdup was due to payout issues over all the songs that were playing (in full or in part) during the episodes. Whether that was the issue or not, it's out there for order.

The Singularity is Hype

March 24, 2007 16:21:21.990

I finished "Future Hype" this morning on the train ride up here to Cambridge - it was a decent book, and a fast read. The author's main point: don't believe all the hype you hear about how things are moving so much faster now than they ever have been.

My history reading has made me skeptical of that idea, and one of the examples given by Seidensticker is communications. Yes, the internet is an advance: but consider earlier communications advances, and where they took people. When the net came online, we already had news traveling around the globe nearly instantly, via phone, television, and radio. Now go back to the early 19th century, before the telegraph was invented - communications took days, weeks, or even months. Ambassadors back then had much more power and latitude than they have now; when the young US sent an official to deal with the Barbary pirates in 1805, he wasn't going to get new instructions from Washington for months - he was left to his own best judgement. In 1858, there was a transatlantic cable - suddenly, the President could give his foreign (at least in Europe) ambassadors new instructions anytime he wanted.

Consider that upheaval. Just within the foreign service ranks of the various powerful nations of the day: foreign office staff went from being powers unto themselves to being message carriers in an instant. When the internet really came into its own in the early 90's, it didn't have anything like that impact.

The book is filled with similar anecdotes, and should reset any thinking person's notions of how fast change is happening. The early industrial revolution, for instance, changed the lives of the average Westerner a lot more than anything that's happened in the last 50 years - look at the changes taking place right now in places like India and China to see a modern day example of that.

Slightly Better Connectivity

March 24, 2007 10:31:22.504

I had a pleasant visit with Bruce Badger this morning at Paddington Station - we got some coffee before I headed up here to Homerton (SPA 2007). The good news: better connectivity. The bad news: Untill Monday, it's pay as you go at 1 pound sterling per hour. Ouch!

InfoWorld on Dead Tree, Dead?

March 24, 2007 4:50:00.696

ValleyWag is reporting that InfoWorld is going to shutter their print edition:

InfoWorld, the long-standing weekly magazine to which enterprise technology startups made a dutiful pilgrimage, is to shut down, according to a newsletter report. The title, owned by the IDG publishing group, will continue to operate as a web news site; but the print magazine, which carried celebrity columnists such as Ethernet inventor Bob Metcalfe, is dead after nearly three decades. Tech titles have been the first, in the magazine industry, to fall to web competition. Red Herring magazine, as we've reported, can't compete with Valley insider blogs such as Techcrunch and Gigaom.

I have mixed feelings about that. On the one hand, I realize that the print edition costs a lot to produce (and is mainly advertiser supported - I get my copy free). On the other hand, I like getting the print edition - I rarely go to the websites for things like InfoWorld, ComputerWorld (et. al.). I read some of their stories, but only the ones that go by in my news reader. With the print edition - like a regular newspaper - I read stories I wouldn't necessarily be looking for.

Sadly, my interest in grazing the print edition just isn't part of a big enough market to justify the ongoing print editions. I don't pay for InfoWorld, and I don't currently pay for any newspapers, either - so my inchoate desire for hardcopy is just that.

An inauspicious start

March 24, 2007 3:23:06.942

If I were superstitious, I'd say that someone was sending me a message. Blazing hot hotel room, bad WiFi. Then, something truly weird happened to me last night. I got up to go to the bathroom - last night's airplane dinner was not sitting well with me - and then I found myself lying on the floor, confused. I have no memory of falling down - I must have passed out. I came away from that with a scrape on the forehead and a sore front tooth (only thing I can figure is that I must have landed on it).

I had something similar happen to me when I was very sick as a teenager - but that time, I woke up on the way to the floor (and believe me, that was no fun). This time, I have no memory of passing out at all, nor of hitting the floor. When I woke up, I was disoriented enough to not be sure about where I was. Fortunately, everything seems fine this morning.

The only thing I can think of is that dinner - just before it happened, I had fairly intense discomfort in my lower abdomen. I sure hope the rest of the trip goes better than this...

Pathetic Connectivity

March 23, 2007 20:45:10.650

Well, the Sheraton Heathrow has two things going against it right now - mostly non-existent connectivity, and the temperature of room is sauna-like. Not a great start to the trip :/

The business is changing

March 23, 2007 20:44:48.953

Glenn Reynolds on falling CD sales:

The music industry blames piracy, but other factors -- from the ability to just buy the songs you like, and not a CD full of filler, to competition from other things like games and the Internet, to the fact that releases tend to suck more than they used to -- seem more significant.

I brought this topic up the other day, and I think I had it right then - the business is moving back to a singles model. The "album oriented" period is coming to an end, and it's a painful adjustment - for studios and for artists.

This doesn't mean that the album will go away; but it does mean that album sales will no longer be the driver for the industry.

See you on the other side (of the Atlantic)

March 23, 2007 9:21:32.108

I'm about to board my flight, so it's time to shut down and pack everything back up. As usual, I'm completely *cough* ready *cough* for my Sunday event - I'll be doing last minute preparation on the plane :) I also bought two books that look interesting:

  • "1491", which looks at pre-Columbian America as a more complex thing than we have been taught
  • "Future Hype", which looks to debunk the "things are changing faster than ever" meme.

WiFi at O'Hare

March 23, 2007 8:47:32.820

Getting WiFi access here at O'Hare in Chicago is easy enough - finding a place to plug the laptop in - not so much. With so many of us lugging laptops around, would it be too much to ask to provide a few more outlets?
