I should mention that I've seen a few cases for the iPhone 4 and I think Apple's "bumper" is the best. It's unobtrusive, it's consistent with the style of the phone, and it feels like I'm holding a phone and not a phone wrapped in something.

I didn't get the bumper originally but did after a couple of weeks — not at all because of any antenna issues, but to keep the phone from sliding off my desk with the slightest accidental nudge.

Benefits of the bumper:

• The rubber edges provided a nice amount of grip so that the phone stayed in place.
• The phone was lifted slightly off the table, so if there was a bit of grit on the table the glass on the phone wouldn't get scratched.
• I could lay the phone down on its face without fear of scratching the front; this gave me slightly more privacy in the event that I got a sensitive text message.

Drawbacks:

• The bumper doesn't fit in the dock.
• The slot at the bottom is too small for the connector on my third-party docking cables.
• The rubber is a little too grippy; it snags against my pocket when I'm pulling the phone out.

I don't mind the first drawback, because I don't use a dock. I don't mind the second, because I have plenty of Apple cables. The pocket-snagging, though — that was a minor annoyance but one that was repeated many times a day.

My solution was to remove the bumper and instead apply four translucent rubber dots to the back of the phone. As you can see from the packaging, these flat dots are also called "bumpers." They are originally to keep lamps and vases from sliding and scratching furniture.

Benefits of the dots:

• I'm back to the original sleek feel of the phone, which I like.
• I get the gripping benefits I got with Apple's bumper.
• The pocket-snagging is no longer an issue.
• There is airflow under the phone, sort of like what Bluelounge's Cool Feet do for laptops (the effect is probably negligible, but the phone does get pretty warm sometimes).
• The dots cost practically nothing.

I could probably run a scam on eBay advertising brand-new iPhone "bumpers" for five dollars apiece.

Drawbacks:

• The back of the phone is now ugly — but when I'm using it I only look at the front anyway.
• I'm no longer comfortable laying the phone face-down — but that's a tradeoff I can live with.
• Pocket lint will gather around the edges of the dots — but I can live with that too.

I forget exactly when I did this, but after a few days the dots have stayed stuck on pretty well. No signs of peeling. I got mine from Bed Bath and Beyond, in a package that included more dots and more kinds of dots than I needed. They might also be available at hardware stores or office supply stores.

[Please see update below — this has nothing to do with the MacPaint page.]

This has been news for at least a day or two:

For those who want to see how it worked "under the hood", we are pleased, with the permission of Apple Inc., to make available the original program source code of MacPaint and the underlying QuickDraw graphics library.

What's odd is how the web page at the Computer History Museum made Safari 5 freak out when I tried to post the link on Facebook. I tried pasting into the Link field, expecting Facebook to display a text excerpt and select a preview image like it always does. Instead I got an empty window with this in Safari's address field:

http://www.facebook.com/ajax/composer/attachment.php?
data[url]=http%3A%2F%2Fwww.computerhistory.org
%2Fhighlights%2Fmacpaint%2F
&app_id=2309869772&stream_id=724065703
&composer_id=c4c46efc1298210b2a81b4

I thought I could get around this by pasting the link into the "What's on your mind?" field. Now Facebook did display an excerpt and an image, but the "Share" button had no effect.

Ironically, Safari's "View Source" menu item is disabled when I go to the page in question.

What could be so freaky about a simple web page? From a quick glance at the page source (viewed in Chrome, which had none of the above problems), it seems to be basic HTML and JavaScript.

Seems like I should report a bug to either Apple or Facebook — probably both — but I'm kind of busy now.

UPDATE: As I learned from Marquis's comment, this happens in Safari with any link — even plain old http://www.google.com. So it has nothing to do with the Computer History Museum site. I tried the latest versions of other browsers:

• Opera 10.60: Behaves like Safari (blank window with AJAX URL).
• Firefox 3.6.7: I paste the link and hit "Attach", and nothing happens.
• Camino 2.03: No problem.
• Chrome 5.0.375.99: No problem, as I mentioned earlier.

The smack-talking is not over. The co-CEOs of RIM had this to say:

Apple's attempt to draw RIM into Apple's self-made debacle is unacceptable. […]

CrackBerry is hosting a poll which they say refutes Jobs's claims:

Update: Well, after a few thousand quick votes it seems some 86% of us BlackBerry Bold 9700 users think El Jobso's evidence is a big pile of BS. As for the 14% who think it may hold water, well, I'm sure some of those must be legit… but the numbers speak for themselves. Sorry Steve – it seems you became part of the media you like to beat up on with this one… making a story where one doesn't actually exist.

Let me see if I understand this paragraph correctly.

1. If a vast majority of users don't have a problem with your phone, there is no real problem and it's irresponsible to drag that phone into a media circus. More importantly, this logic doesn't apply to the iPhone, only to BlackBerry phones.

2. If a minority doesn't agree with your predicted poll result, they're probably lying, but the majority voters in your self-selected audience are, it goes without saying, beyond suspicion.

Got it.

I just realized the RSS link on this page was for my other blog. Oops!

On another note, I'll be uploading files from last night's CocoaHeads in the next day or two — I want to clean up some things.

Daniel Jalkut on saying "yes":

When someone asks me to speak at a conference, write an article, give a toast at a wedding, attend a conference, or just to have lunch, my gut reaction is to refuse.

Almost every public thing I do that pulls me away from my computer and out of my house, comes from saying yes when I want to say no. I psyche myself up, remember that this life isn’t going to drive itself where I want it to go, and step up to the plate.

Saying "yes" has been a recent theme for me too, though maybe in a different way. A couple of months ago I had a flurry of social engagements. It was an atypical time for me because generally I don't get out that often. At the time I thought it would be good when things quieted down because I would finally have time to get things done. But looking back, I see I got quite a bit done during that time. And when things did quiet down I gradually got more inert and inactive, and less got done than when I was running around and squeezing work and errands between social outings.

I still believe I am an introvert and time alone to refuel — blessed solitude — is absolutely crucial for my mental health. Being left alone is also a professional necessity: as a programmer, I need long, quiet blocks of time to feel productive and satisfied. But I also need "yes" activities to bounce me around sometimes. Otherwise, like a pinball that never hits any bumpers, I tend to roll down the drain. So I'll try to look for more of those opportunities, and accept more of them when they come my way. I'll also try to recognize which kinds of events tend to energize me rather than drain me.
