    Free bicycles to borrow at Marymoor Park


    Marymoor Park just keeps getting better.

    Just this year, they added a little Subway sandwich shop, so you don't even have to pack for a picnic in the park. Next, free Wi-Fi (sponsored by MSN). Then movies in the park (sponsored by First Tech Credit Union).

    The latest addition is free bicycles (sponsored by Dasani). Show a photo ID and you get a cardkey that gives you access to one-speed coaster-brake bicycles you can borrow for the day.

    If you squint you might be able to make out my name


    Late Tuesday night, Jenny Lam, the creative director for this year's PDC, came by our hallway and asked for permission to rummage through our offices for "stuff". They were looking for props to use to decorate a developer's cubicle in a video they were filming for the conference. I was able to loan her a framed letter of appreciation and my pass to the Windows 2000 launch. I used to have a lot more junk in my office, but I went on a cleaning binge during our last office move and the really cool mementos ended up at my house. If you watch the movie and squint you might be able to make out my name on the personalized items, but I wouldn't hold my breath. My stuff will be on screen for probably a quarter of a second, and I'm guessing it won't be big enough to read anything of significance. (Jenny tells me that one of the things in the cubicle is a forgery. See if you can spot it.)

    They were able to get much cooler stuff from my neighbor's office. Among other things, he had a chemical model of the caffeine molecule.

    Incidentally, Jenny puts my Martha number at two. I've met Jenny, and Jenny was personally interviewed by Martha Stewart. I just think that's so neat, being two steps away from The Martha.

    Windows 95 crashes a cash register


    Not everything related to the Windows 95 launch went well. The St. Louis Post-Dispatch reported that a local CompUSA store found that their cash registers crashed at midnight, forcing eager customers to wait ninety minutes before the problem could be resolved. The cause: A bug in the cash register software which had lain undiscovered because the store had never stayed open past midnight before!

    And there was the the launch of Mindows 95 in Hong Kong.

    Not one to sit by and miss out on all the attention, Apple responded with its absolutely brilliant counter-advertisement.

    Marymoor Park summer movie series 2005 is nearly over


    Every Wednesday evening in August of this year, Marymoor Park will be showing a movie. Tonight's movie is Bend It Like Beckham. The movie begins at dusk, and a $5 donation is suggested, proceeds to be shared between the park and a local charity. The charity tends to be thematically related to the movie; for Beckham, for example, part of the money will go to the Lake Washington Youth Soccer Association.

    A ticket to the Windows 95 launch


    A limited number of seats at the Windows 95 launch were available to the product team, so there was a lottery to see who would get one of those tickets. The remainder of the team would be standing on bleachers hidden behind the stage, to be unveiled at the grand climax of the product launch festivities.

    I happened to have been a winner in the ticket lottery, but the fact that there weren't enough seats for everybody created some degree of grousing among the have-nots. As a show of solidarity, I forewent the special VIP pass and ticket, instead taking my place in the crowd of red, blue, yellow, and green T-shirts waiting backstage and giving the pass and ticket to a colleague who really wanted to be in the tent.

    While I waited in the staging room to be positioned for the grand finale, I was somewhat surprised to see my colleague in the room with me. She gave me back my unused VIP pass and ticket, saying, "It didn't feel right being out there in the tent. This is where I belong."

    I probably have the only unused ticket to the Windows 95 launch.

    While standing on the bleachers behind the screen, we could hear everything going on. When Jay Leno disappeared backstage to head off to his next scene, he emerged between the two sets of bleachers. We silently waved at him, but he was obviously focused on his job and didn't have time to schmooze with us.

    It was very hard staying quiet for so long backstage. Our presence was supposed to be a surprise; any noise would give us away. There were moments where whispers got out of hand and people had to wave frantically (or—heavens—shush!) to restore quiet. I thought for certain one of our out-of-control moments had let the cat out of the bag, but from talking to people afterwards who were in the tent, I learned that nobody noticed a thing.

    Our only instructions from the director were "Wave, clap, and cheer!", keeping up the energy until the last of the crowd had filed out. Everything beyond that was improvised. Somebody started up a cheer, with half of the bleachers shouting "Windows!" and the other half responding "95!" I'm sure there were other things we did to maintain the excitement, though I can't remember any of it now. I just remember that after a while I got tired of smiling and clapping but kept it up because I was on the aisle next to all the attendees, and that's show business!

    Buying an entire Egghead Software store


    During the development of Windows 95 (which released to the public ten years ago today), application compatibility was of course a very high priority. To make sure that coverage was as broad as possible, the development manager for Windows 95 took his pick-up truck, drove down to the local Egghead Software store (back when Egghead still existed), and bought one copy of every single PC program in the store.

    He then returned to Microsoft, unloaded all the software onto tables in the cafeteria, and invited every member of the Windows 95 team to come in and take responsibility for up to two programs. The ground rules were that you had to install and run the program, use it like a normal end user, and file a bug against everything that doesn't work right, even the minor stuff. (Of course, you had to provide the program to the person investigating the bug upon request.) In exchange for taking responsibility for ensuring that Windows 95 was compatible with your adopted programs, you got to keep them after Windows 95 shipped. If you did a good job with your two, you could come back for more.

    The cafeteria was filled with Windows 95 team members, browsing through the boxes upon boxes of software like bargain-hunters at a flea market. And there were the inevitable "What'd you get?" comparisons afterwards.

    I picked up only one program, an English/German automatic translator. It ran fine but produced pretty bad translations. (Not that the quality of the translations was in any way the fault of Windows!)

    Why are icons multiples of 8 pixels in width?


    Icons are all multiples of eight pixels in width. It's not just because computer people like powers of two.

    Back in the early days of Windows, video cards were monochrome or, if you were lucky, 16-color. These were all planar video modes, the mechanics of which were discussed earlier. Now imagine copying a bitmap to the screen where both the bitmap and the screen are planar. If the starting coordinates of the destination was an exact multiple of eight, then the bitmap could be copied via block transfer instructions. On the other hand, if the destination was not a perfect multiple of eight, you had to do a lot of fancy bit shifting to get it onto the screen.

    This is the source of the CS_BYTEALIGNCLIENT window class style. With this style set, the window manager will try to position the window so that the x-coordinate of the client rectangle's upper left corner sits at a perfect byte boundary of video memory. If you were running at a 1bpp video mode (monochrome or 16 color), this meant that the x-coordinate was a multiple of eight. By positioning the window this way, a bitmap copied to the upper left corner of the client rectangle would be copied via fast block transfer instructions.

    If you look at dialog box dimensions from Windows 95 or earlier, you'll find that they are nearly always a multiple of 32 DLUs in width. Since four horizontal DLUs equal one average character width, you had to keep your dialog width a multiple of 32 to ensure that the final dialog size was a multiple of eight.

    Keeping bitmap widths such that they represented exact byte boundaries was important for performance on the machines of the day. Copying blocks of pixels around was typically performed in three major steps: A thin vertical strip from the left edge of the bitmap to the first byte boundary, then the bulk of the bitmap up to the last byte boundary, and finally a thin vertical strip from the last byte boundary to the right edge. If you kept your eyes open, you could actually see these three stages of drawing occurring. (Like I said, machines of the day weren't all that fast.) Keeping things byte aligned and at byte width meant that the two thin vertical strips had zero width and therefore could be optimized out.

    Of course, in today's world of 32bpp displays, all these old considerations are largely irrelevant.

    How do you convince developers to pay their "taxes"?


    The Tablet PC team have a tough task ahead of them at this year's PDC: They have to get people to care about power management.

    The reason why this is tough is that power management is rarely a deal-maker. If a user is evaluating, say, personal finance software, how much weight are they going to place on which program consumes less battery power? That's probably a third- or fourth-level tiebreaker. No amount of power management is going to overcome the fact that your program's interface is harder to use than your competitor's. Nobody ever said, "Oh, yeah, I switched my word processor from X to Y because X was chewing too much battery power." When a battery doesn't last very long, users tend to blame the battery, not the software that is draining it.

    Power management falls into a category some development teams call "taxes". It's something you do, not because it actually benefits you specifically, but because it benefits the software landscape as a whole. Other taxes include making sure your program plays friendly with roaming user profiles, Fast User Switching, Hierarchical Storage Management, multiple monitors, Remote Desktop, and 64-bit Windows.

    Of course, not all development teams in the world are so diligent as to pay all their "taxes". I suspect most cheat on their taxes, and some of them just don't pay any at all.

    So here's my question to you: How do you convince developers to pay their "taxes"? (Should developers have to pay taxes at all?)

    This might be for real, even though it comes out at 7am


    One of our researchers IM'd me yesterday to let me know that someone she interviewed mentioned that some people suspected that I wasn't real because most of my posts are published at the same time every day.

    I dunno. The evening news comes on at the same time every day, but I'm pretty sure they're real. Maybe I should be more suspicious.

    If I were real.

    Justifiable assault with folding chair


    Everybody's lunchtime conversation a few days ago was the riot at a used laptop sale in Richmond, VA. [Local coverage.] What got me was this fellow Jesse Sandler:

    "I took my chair here and I threw it over my shoulder and I went, 'Bam,'" the 20-year-old said nonchalantly, his eyes glued to the screen of his new iBook, as he tapped away on the keyboard at a testing station.

    "They were getting in front of me and I was there a lot earlier than them, so I thought that it was just," he said.

    Because if somebody cuts in front of you in line, you are perfectly justified in assaulting them with a folding chair. That's one of the guiding principles this country was founded on.
