Re: [FRIAM] Wind Farm Comprssible Flow!
Nick -- Sure. Think about tires. Air is compressed in them. By the way, those who advocate filling tires with Nitrogen sometimes conveniently forget that our atmosphere is already 78% Nitrogen. It makes a slight advantage in racing tires, but most of us run with underinflated tires anyway. It's one of the cheapest and easiest ways to boost fuel efficiency - make sure your tires have the proper amount of compressed air. - Claiborne Booker - -Original Message- From: Nicholas Thompson nickthomp...@earthlink.net To: friam@redfish.com Sent: Thu, Nov 26, 2009 3:41 pm Subject: Re: [FRIAM] Wind Farm Comprssible Flow!

Re: [FRIAM] Owen and the Mac
On Nov 26, 2009, at 2:23 PM, Jochen Fromm wrote: Cool, do you remember the time with Andy Hertzfeld, Bill Atkinson and Steve Jobs? Yup. Interesting history. Jobs goes to PARC and is blown away. Starts the Lisa project (precursor to Mac). Lots of Xerox folks went to Apple, me included (I was at WARC .. the Webster NY research center focusing on printer code). Larry Tessler found about my printing work and invited me for an interview. I had been bringing the Alto, Xerox's first personal computer, technology to Webster, even building a hardware lab so that we could add additional S-Registers to the micro-code system, thus multi-task printers: receiving networked documents and printing them. My first talk at Apple was why they could not solve the WYSIWYG problem especially with non-rational aspect ratios (i.e. h/w of printer not multiples of the screen). We had proven the problem to be hard. But heuristics were fairly acceptable. But still computationally intense. Brought along a couple of engineers with me, most famous being Steve Capps the hero of the Newton. Recently I read one of the biographies about Steve Jobs (Icon from Jeffrey Young and William L. Simon). Both Hertzfeld and Atkinson are mentioned in the book, but no word of Owen Densmore. I was one of the less well known guys 'cause I came over from the Lisa project to do the printing. I asked Andy and Bill what their approach to printing was going to be and it was to do screen dumps! Bad idea! We re-engineered QuickDraw so that there were hooks for all the graphics calls, and so printing could just give the application a large window that was the same size as a piece of paper. It was simple enough that the Mac pirate crew liked it. And Steve wanted a laser printer so this architecture worked really well. I ended up leading the PrintShop team that worked with Adobe. We built a PostScript interpreter of QuickDraw which we hooked up to the hooks above. Bloody hard. They must have missed something... Have you been the freshman in the team responsible for import/export functions, language translations and printing programs? Printing, fonts, and a simple multi-processing stunt that let Microsoft print and use their applications at the same time. My name is inside the first casting of the Mac case which had the names of the other engineers. Around 12 of us, as I recall. To me, the two heros of the Mac were Bruce Horn (Resource forks and much much more) and Larry Kenyon, the OS guy. Both were under extreme pressure and had absurd conflicts with engineering management. Interesting how we all left within a year of the release of the Mac. The carpet baggers (outside managers with absolutely no understanding of the Mac and computing) came and made Apple absolutely hell. I spent 2 hours once with Jobs talking about building the Big Mac, using Unix, PostScript, and TCP/IP networking. He listened. But also left, but then the NeXT machine was a lot like what I wanted. -- Owen FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College lectures, archives, unsubscribe, maps at http://www.friam.org
Re: [FRIAM] Owen and the Mac
Here is another picture http://www.folklore.org/ProjectView.py?project=Macintoshgallery=1 Somehow Steve Jobs got all the money, Andy Hertzfeld and Bill Atkinson got all the glory, and you got all the hard work? What a distribution. My first task in my first job after university was working on printing procedures as well. Writing printing functions is not a very thankful task, there is always a printer, printer driver or paper size which does not work. And the system would work without them, they do not belong to the core of the system. In every software system there is a core and a shell - the core that's the part which gets, stores, and processes the data. It is the part which is encapsulated by the API. The shell consists of additional parts: localization and translation, import and export, and printing. The system would run without the shell, it would only be a bit less useful. If you join a software team late, your first work is often at this shell - if you would join Google as an engineer today, you would probably work on some Javascript problems in the calendar functions. Or printing functions for the calendar. I wonder what Software Wizard Andy Hertzfeld is doing at Google currently? -J.
