I made previous reference to a scan available online of a map of San Francisco and my intention to put that map on a Google Map. Well, I’ve spent way more time on it than I anticipated but it finally, actually works as I originally envisioned.
Challenges:
- Google Maps are aligned with “true north”; the old map is aligned with some other north, possibly magnetic north at the time the map was made
- the horizontal and vertical scales are not the same
- the old map apparently fell apart and was taped back together; this was not done perfectly and there are a few small gaps and missing bits
- the scale tends to vary over relatively small distances; agreement between the tiles I generated and Google’s tiles can wander even within one tile
I ultimately decided not to fix items 3 and 4. Fixing the gaps tended to do more harm than good and scale variances require far more graphics-fu than I am ever likely to have.
If you want to cut to the chase & see the map, it is here.
Here is what I did: Read the rest of this entry »

I tweeted a few days ago about an article on SFGate about the little street we live on. A couple days after that, the SFist posted an old map of the city from 1862.
Take close look at the map, in the lower left corner. If you follow Market Street to the lower left corner, near a large number 11 is “Kate Street”. This street no longer exists, and it leads to an area labeled “Hospital Area”; this is now Duboce Park and three cul-de-sac blocks of homes, one of which is now Potomac St. It’s fun to see the map agree with what I read in the book by Harry Nimmo referenced in the article.
I am entertaining a fantasy of creating a Google Map of the area and replacing the tiles with the old map. Hopefully I’ll actually get to that.
UPDATE: I’ve checked the Google Maps API, and it seems what I need to do is a “Custom Map Type”, which The Google deems an “Advanced Topic.” They put this in red; I may be in over my head!

We have finally seen the HP Slate, and it is … a PC with no keyboard. Add the Kindle application and it’s at least a general-purpose PC. But we found out nothing about battery life, pricing, data plans/connections, or system specs.
That, and there is no mention of it on HP’s web site. I managed to find a press release, but I am not sure if the device shown on stage is mentioned therein.

“Maybe it’s awesome”
Props to Mr. Gruber for the perfect summary of Microsoft & HP’s tablet/slate prototype. Complete with stylus! That is just what the world is waiting for, two years post-iPhone. A stylus! Can’t wit for the demo.
OK so seriously, there are a few things missing from this demo:
- twitter
- facebook
- gmail
- flickr
- SMS
- chat
ie, everything a modern consumer cares about on their (mobile) computer. A couple inescapable conclusions from this information:
- Microsoft has had a skunkworks project for a new mobile operating system that looks nothing like any Microsoft product and specifically does not emulate any current features of Word, Excel or Outlook
- Microsoft has given up one the Office/Windows duet that has given them two decades of profitability
- this project has somehow seen the light of day, but hasn’t been released in any way shape or form

More iSlate speculation: Apple will have to figure out tethering before they launch a tablet/slate device.
Why? If Apple is going to launch a mass-market general-purpose tablet device, it is going to need network access. Very few consumers are going to be willing to accept that they have to pay for a second data plan. Apple won’t launch such a device if it can only tether to non-Apple phones!
So, if Apple were to launch a game-changing tablet device, it will have to tether to the iPhone. Tethering was supposed to be available on the iPhone by now, but of course it isn’t. Maybe we’ll see AT&T supporting only this new tablet tethered to iPhones, which would at least permit Apple to hold a fig leaf in front of AT&T when they offer tethering to other phones.

Ray Kurzweil has joined the reader fray and his is software only.
So the defection from dedicated readers begins!
A hope for the Apple device that absolutely positively be announced the 27th (unless it is not): a screen that switches between a reflective, low-power mode similar to the Kindle and a higher-power backlit mode for browsing chat, and so on.

The “Skiff” reader that Hearst is working on, at least as described by The New York Times, is Yet Another Kindle Killer. Trouble is, the “Kindle” category has a lot more hype than it has sales, or Amazon would go ahead and release their sales figures. The Kindle doesn’t need killing, at least not yet.
Based on what I hear about the revenue that Hearst gets from Amazon, I am not surprised at all that they want to enter the ‘Kindle’ space and recover some of the 70% they surrender.
The device itself has a lot of appeal. But what is the business model? If the Skiff is a general-purpose computer, it won’t generate any revenue from content because it’s own web browser provides the same content for free. If the Skiff is a dedicated computer (ie provides access to content otherwise unavailable electronically) then people are expected to carry this thing in addition to or instead of a laptop or other general-purpose computer, it is the third entrant in a tiny, or at least niche, market.
Fuchsberg seems to indicate it will be a dedicated, niche device with this quote: “We think there’ll be a market for dedicated readers alongside applications on your phone or tablet PCs.”
Note to Hearst: if the point of the Skiff is to charge people for content, you have to charge everyone, regardless of the device they are using. I think that is why the Kindle hasn’t taken off, at least not as a news reader: who is going to buy a dedicated device for the privilege of paying for content that is free on gear they already own?
