In Wired News: Rooting Around Site With Intent?, Michelle Delio discusses a case in Sweden where a reporter downloaded Intentia‘s Q3 2002 financial statements before they were officially released. Intentia has filed a complaint against Reuters and the reporter in question, claiming they violated various intellectual property and computer protection laws.

Both Intentia and Reuters agree the Reuters reporter obtained Intentia’s financial statement directly from Intentia’s website.

…
But since Intentia did not provide an explicit link to the report, Intentia’s lawyers consider Reuters’ retrieval and early publication of the information a violation of intellectual property and computer system protection laws.

…
The reporter did not use software that would penetrate or search Intentia’s private systems. The reporter did not enter a password in order to obtain the data. The reporter simply went to the area of Intentia’s site where such information is normally posted and found the report.

This just proves once again that most people don’t understand security or the Internet. Placing confidential data on a public website is just asking for trouble. If you need to pre-publish data (e.g. to make sure it can be accessed from the outside before announcing it), put a password or other ACL on it!

These people need SelectAccess :-).

Well, Weight Watchers appears to be working for me. 6 weeks, 12.6 pounds weight loss; see the link or the graph in the sidebar.

I like the system. It’s simple enough to carry around in my head. It’s not a “fad” diet, so there are no food restrictions; anything goes as long as it fits into my daily points allottment. This cannot be under-emphasized: the combination of knowing which foods are “expensive”, combined with the ability to plan in advance for those expensive foods, is what is working for me.

I’m a geek; systems like this appeal to my orderly mind. With data, useful decisions can be made; guessing and waving-of-hands wasn’t working for me. And data is everywhere; Weight Watchers publishes books; lots of websites publish recipes; and the USDA Nutritional Database is online! In fact, I have a copy of the database, combined with a search engine that calculates points. (No link, sorry; it’s password protected so that they don’t send their lawyers after me :-).

I joined the At Work program at Lombard, where my friend Gerry works. That’s important; it’s a 5 minute walk from my office, and I go at lunch time instead of in the evening when I’m usually busy. I’m pretty sure that if I had to switch to evening meetings near my home, I’d stop going because of the inconvenience factor (even though the closest meeting is about a 15 minute walk from my house :-).

I can get by without the motivational stuff that is discussed in meetings; I internalised most of that stuff years ago, as part of other changes in my life. On the other hand, the Weight Watchers scale is accurate. That lets me measure steady weight loss, which is part of my incentive to stay on program. With the best personal scale I’ve found so far, I could vary my weight by 5 pounds just by leaning forwards or backwards. Most of them probably work ok, but it’s impossible to measure a 0.4 pound loss on those things.

(Anyone who has a good scale recommendation, send me e-mail. :-)

I also find the meetings useful for some of the tips exchanged between the group, but as a ‘netizen I can get those online, too.

Anyway, overall I’m quite happy with the program. It’s is worthwhile investment, in my humble opinion.

From Spin of the Day:

Nike Files Supreme Court Brief
Nike has asked the US Supreme Court to review a California Supreme Court ruling that Nike’s public statements on the work conditions of its overseas factories be considered commercial speech and be subject to truth-in-advertising laws. Nike argues that the ruling is “profoundly destructive of free speech.” The ruling applies to statements made by Nike in op-eds, letters to the editor, and comments made to reporters. PR trade publication The Holmes Report wrote that as a result of the ruling, Nike would not be releasing its annual corporate responsibility report. A number of PR trade organizations have joined together to file a friend-of-the-court brief. “At stake is our ability to do the kind of work we do in regard to public debate,” Council of PR Firms president Kathy Cripps said. “If the US Supreme Court does not hear this case, a lot of what we do will be considered commercial speech. This is possibly the most vital issue the industry is dealing with, and we need to come together to defend our position.” Source: The Holmes Report, October 21, 2002; PR Week, October 21, 2002

Is it just me, or is this Nike and the PR firms arguing in court to protect their right to lie to the public? <shudder>

So this year, my father in law (the gas furnace expert) tells me that he refuses to do the annual inspection/cleaning on our furnace, because he thinks it is dead. If it is dead, he is required (by law) to turn off the gas, so that we don’t foolishly kill ourselves.

So fine, we decided it’s time to replace the furnace. We do the research, find a contractor, and pick a furnace. We decided on a mid-efficiency furnace, because dad-in-law said that (because of drafts in our house and the ductwork) we wouldn’t gain a significant advantage from a high-efficiency furnace. A high-efficiency furnace needs to be vented and exhausted through ABS piping instead of a conventional chimney, increasing the cost.

The installers showed up today…

In 1994, our house was renovated to add a new second floor on top of the front of the house, above what was previously a flat roof. As part of the addition, they had to extend the chimney to clear the new (peaked) roof on the front of the house. (Man, roofs are a pain :-).

Building code at the time required a metal chimney liner, to improve draft, reduce the amount of cruft in the exhaust path, and prevent exhaust fumes from leaking from the chimney into the house. Now this house already had a chimney liner, probably from an older furnace upgrade.

Did they remove the old chimney liner? Of course not. Instead, they removed its cap and built an unlined extension on top of the old chimney. This means the existing liner cannot be removed (removing it requires removing the extension). However, our new furnace cannot be installed without bringing the chimney up to code, which requires a continuous liner in the chimney; installing one means first removing the remains of the old one.

Because the new chimney extension wasn’t properly capped (until the raccoon guy added a mesh screen in spring 2001). So the old liner was half blocked with two dead birds and a whole bunch of sand from the new chimney extension. At least we’ve got that stuff cleared out, so the existing furnace should work a bit better while we ponder our options.

The two options are: 1) high-efficiency (condensing) furnace. 2) repair the chimney. Both options, I guess, require at least another $1000, which (naturally) I don’t have.

Home ownership is fun. Ask me about the whole raccoon story sometime…

Owning a home is so much fun…

When we moved in to our current house two years ago, we were warned by our home inspector that our flat roof would probably leak, and our furnace was on its last legs.

Our flat roof had been “repaired” in 1998, so we weren’t too worried about getting to it right away; it was October (almost winter), and so not a good time to be doing roof repairs.

Four months later (in February), we had a brutal snowstorm that turned to rain. the snow blocked all of the downspouts, trapping the rain on the flat roof. There was a dormer sticking out of the flat roof, protecting the stairs to the newly added second floor. The water level rose until it could get under the over the roof lip around the dormer, and then poured into the house, filling the ceiling underneath. WE discovered this when the door-frame nearby started dripping water; by this point the ceiling was full and water was pouring down the insides of the walls. Shortly thereafter the ceiling one floor down started dripping.

We went up on the roof (still in the rain), and shoveled all the snow and ice off to stop the overflow. Then we poked a hole in the ceiling, and pulled out about 60 litres of water. (A wet ceiling sags, creating a significant volume of trapped water :). Alas, shoveling the roof turned out to be the last straw for the roof; it started seeping into the room next door.

This was about when we decided that flat roofs are evil, and needed to be exorcised. Now winter is a bad time to be doing roof work, so we waited until spring. By the time Spring 2001 had rolled around, the stock market had collapsed and my wife had been laid off; suddenly there was no money for major renovations.

So for the next many months, we had two uninhabitable rooms in our house, because every time it rained, the ceilings would drip. We finally scraped together a plan, enough money, a building permit, and a contractor in December 2001. They were wonderful; in 5 days they stripped the old flat roof and built a wonderful peaked roof in its place. As an added benefit, I now have a nice attic storage space where the flat roof used to be.

When stripping the flat roof, we discovered that the previous roof contractor had simply laid insulation and a new (1-ply) rubber membrane on top of the existing gravel, on top of the old flat roof. This meant that the new rubber membrane had no support, which is why it disintegrated in only three years. It also explained some of the strange behaviour we saw; the ceiling would leak a day or two after rain, because it took that long for water to percolate through both roofs and the gravel layer.

Up next? the furnace…

Even after reading the “how we did it” section, I’m still impressed by Escher’s “Ascending and Descending” in LEGO…

I used to run, as a kid; I loved it. Some of my friends are (now) runners. I’d been thinking about taking it up again, when along comes this post…

Becoming a runner is actually not that difficult. Not surprisingly, it involves running. There’s other stuff, too, eventually, but running is the important part. If you can run a mile, run a mile. If you can only run around the block, run around the block. Tomorrow you’ll run around the block, and the next day you’ll find you can run around two blocks. And next week you’ll find you can run a mile. Then one day you’ll run a mile, then stop to catch your breath, then get invigorated and run another mile.

And then you’re a runner. That’s it, really.

There’s other stuff too, but it doesn’t really matter until you’re already a runner. […] Don’t worry about any of that now. Just run. Running is key. Otherwise you’re just another fat schmuck lying on the couch reading Runner’s World.

From my friend Greg Wilson; source unknown:

British poultry farmers trying to raise ostriches in the 1990s called in
scientists to find out why their birds were failing to breed. Careful
observations confirmed the birds were courting the farm workers rather
than each other, Norma Bubier of Pro-Natura UK and colleagues reported
in a seminal paper in British Poultry Science (vol 39, p 477), entitled
“Courtship behavior of ostriches toward humans under farming conditions
in Britain”.

The research was no laughing matter for the scientists or the farmers.
Ostriches are big. “You wouldn’t want to be in a pen with an amorous
ostrich, because if it tried to climb on top of you, you’d be in serious
trouble,” says Charles Paxton of the University of St. Andrews. Most of
the birds had been hand-raised by humans, and Paxton suspects they
identified with people when they went looking for mates. However, the
British ostrich industry collapsed before he could investigate further.

So RedHat 8.0 is out, and supposedly (according to the reviews) has a nicer desktop experience than in the past.

Windows is vexing me.

There are two versions of WINE floating around now; one that will run most OpenGL games, and the other that supports MS Office, and will run many multimedia browser plugins under Mozilla.

The only thing I really use Windows for (at home) these days is browsing, games, a couple of relatively innocuous utilities, and the enormous Excel spreadsheet that is my Rolemaster character.

Conclusion: it’s time to attempt, once again, the Linux-only laptop. First, I have to liberate some “copious spare time”….

I discovered that I was actually using IPv6 (quite successfully) when I turned it off and a bunch of things broke :-)

So the state now is:

• I’ve re-enabled IPv6 on the cfrq.net network.
• I’ve disabled IPv6 on Windows, since that’s what was really bugging me.
• I’m still running Apache 1.3.26; it supports PHP, and I haven’t rebuilt PHP for Apache 2.0.40 yet.
• I’ve shot zebra dead as a doornail, and I’m back to using static routes. With my CIPE patch for detecting the liveliness of the network connection, this gives me relatively efficient routing even in the face of my ever mobile laptop.

The experiment continues…
