| 40 <p>After all the months of 50° North Latitude winter—icy-sharp in most | |
| 41 of Canada, wet and dark here in Vancouver—the soul, the spirit, and the | |
| 42 libido all spring to life when the sun comes back. We’ve had a solid year of | |
| 43 crappy weather, but this last Saturday through Monday were solidly summery, | |
| 44 bright | |
| 45 and warm; and in this season the days are already long and each gets | |
| 46 longer so fast you can feel it.</p> | |
| 47 <p>On the back porch, our pear tree’s branches were silhouetted against the | |

| 63 <p>I’ve been watching our internal leadership conference and spending quite a | |
| 64 bit of time talking in the virtual hallways, and I’ve been surprised at | |
| 65 the intensity of feeling about Mr. McNealy. Yes, there are those | |
| 66 here saying “About bloody time, now we can make some progress” but there’s a | |
| 67 much bigger group that is genuinely emotional about this transition. | |
| 68 Maybe it’s a function of seniority: I never met nor corresponded with Scott, and | |
| 69 he hasn’t been | |
| 70 much of a presence in the company’s conversation in the time I’ve been here. | |
| 71 But there are a lot of smart, seasoned, unsentimental people making it clear | |
| 72 that | |
| 73 he’s been a major force in their lives, at a more personal level than I’m | |
| 74 used to hearing when people speak about executives. I guess also that to a | |
| 75 lot of people, Sun’s vision, for which Scott gets some of the credit, was a | |
| 76 radical and wonderful thing. I first used Unix in 1979 and quit a nice | |
| 77 big-company job | |
| 78 to become a VAX-bsd sysadmin in 1983, so I’ve always kind of | |
| 79 lived inside that vision. | |
| 80 But I’ll tell you one thing, what I’ve been hearing the last couple of days | |
| 81 makes me really regret that I didn’t get to know Scott.</p> | |

| 97 the city I live in, Vancouver, is pretty solidly Jacobsian both in its current | |
| 98 shape and its planning dogma. By choosing to live here I’m empirically a | |
| 99 fan. Oddly, few have remarked how great Jacobs | |
| 100 <em>looked</em>; her face commanded the eye. Which leads me Alex | |
| 101 Waterhouse-Hayward’s wonderful | |

| 103 surprising portraits and thoughts on decoration. W-H’s blog has become one of | |

| 108 Staying with the death-and-betrayal theme, and apparently (but not really) | |
| 109 shifting back 2½ millennia, see John Cowan’s | |

| 129 <p>At | |
| 130 <a href="/ongoing/When/200x/2006/04/13/RoR">that Rails conference</a>, when I | |
| 131 was | |
| 132 <a href="http://blog.garbledygook.com/2006/04/17/ruby-on-rails-podcast-tim-bray-ruby-on-rails-podcast/">talking</a> | |
| 133 to | |
| 134 <a href="http://jroller.com/page/obie">Obie Fernandez</a>, he asked, more or | |
| 135 less “How can Sun love us? We’re not Java” and I said, more or less, “Hey, | |
| 136 you’re programmers, you write software and there have to be computers to run | |
| 137 it, we sell computers, why wouldn’t we love you?” Anyhow, we touched on | |
| 138 parallelism a bit and I talked up the | |
| 139 <a href="http://www.sun.com/processors/UltraSPARC-T1/">T1</a>; | |
| 140 Obie took that ball and | |
| 141 <a href="http://jroller.com/page/obie?entry=will_ultrasparc_t1_emerge_as">ran with it</a>, | |
| 142 saying all sorts of positive things about synergy between Rails’ | |
| 143 shared-nothing architecture and our multicore systems. Yeah, well, good in | |
| 144 theory, but I’m too old to make that kind of prediction without running some | |
| 145 tests. Hah, it turns out that | |
| 146 <a href="http://joyent.com/">Joyent</a> has been | |
| 147 <a href="http://scalewithrails.com/">doing that</a>, and have | |
| 148 <a href="http://scalewithrails.com/downloads/ScaleWithRails-April2006.pdf">76 | |
| 149 PDF slides</a> on the subject. | |
| 150 If you care about big-system scaling issues, read the whole thing; a little | |
| 151 long, but amusing and with hardly any bullet lists. If you’re a Sun | |
| 152 shareholder looking for a pick-me up, check out slides 40-41, 49, and 52-74. | |
| 153 Oh, I gather that the T1, Solaris, and ZFS are OK for Java too. | |

| 172 <p>I got email late yesterday from | |
| 173 <a href="http://blogs.zdnet.com/bio.php#berlind">David Berlind</a>: “Hey, can | |
| 174 I call you for a minute?” He wanted commentary on | |
| 175 <a href="http://blogs.zdnet.com/BTL/?p=2906">a story he was writing</a> that I | |
| 176 think is about the potential for intellectual-property lock-ins on RSS and Atom | |
| 177 extensions. I say “I think is about” because the headline is “Will or could | |
| 178 RSS get forked?”. After a few minutes’ chat, David asked if he could record | |
| 179 for a podcast, and even though I only had a cellphone, the audio came out OK. | |
| 180 The conversation was rhythmic: David brought up a succession of potential | |
| 181 issues and answered each along the lines of “Yes, it’s reasonable to worry | |
| 182 about that, but in this | |
| 183 case I don’t see any particular problems.” | |
| 184 Plus I emitted a mercifully-brief rant on the difference between protocols, | |
| 185 data, and software. | |
| 186 On the one hand, I thought David could have been a | |
| 187 little clearer that I was pushing back against the thrust of his story, but on | |
| 188 the other hand he included the whole conversation right | |
| 189 there in the piece, so anyone who actually cares can listen and find out what | |
| 190 I actually said, not what I think I said nor what David reported I said. | |
| 191 I find this raw barely-intermediated journalism (we | |
| 192 talk on the phone this afternoon, it’s on the Web in hours) a little | |
| 193 shocking still. | |
| 194 On balance, it’s better than the way we used to do things.</p> | |

| 238 <h2 id='p-1'>The Context</h2> | |
| 239 <p>Nothing I can possibly write will add any wisdom to the | |
| 240 millions of words, some 90% of them in excess of needs, written on the subject | |
| 241 of this particular person.</p> | |
| 242 <p>A personal statement: Bob Dylan has long irritated me for, during the first | |
| 243 thirty years or | |
| 244 so of his career, never having given a straight answer to a straight question, | |
| 245 and for writing songs with dozens of boring verses. But they’ll still be | |
| 246 listening | |
| 247 to lots of his performances long after I’m dead, and in recent years he’s | |
| 248 become a better, more direct, interview.</p> | |
| 249 <p>My taste in Dylan is a little unusual: once you get past <cite>One More Cup | |
| 250 of Coffee</cite>, my favorites would be <cite>Baby Let Me Follow You | |
| 251 Down</cite> (from the <cite>Last Waltz</cite> soundtrack) and | |
| 252 <cite>Crash on the Levee (Down in the Flood)</cite> from | |
| 253 <a href="http://en.wikipedia.org/wiki/The_Basement_Tapes">The Basement | |
| 254 Tapes</a>.</p> | |
| 255 <p><cite>Desire</cite>, the record, is hit and miss. <cite>Joey</cite>, | |
| 256 glorification of the life of some mafioso, is flawed in concept | |
| 257 and unlistenable in execution. <cite>Hurricane</cite>, whatever you think | |
| 258 about | |
| 259 <a href="http://en.wikipedia.org/wiki/Rubin_Carter">Mr. Carter</a>, that song | |
| 260 rocks; and <cite>Isis</cite> hits pretty hard too.</p> | |
| 261 <h2 id='p-2'>The Music</h2> | |
| 262 <p>Is there anything in <cite>One More Cup of Coffee</cite> that’s not | |
| 263 perfect? Well yes, in the verses, the | |
| 264 lyrics on occasion drag (“He oversees his kingdom / So no stranger does | |
| 265 intrude / His voice it trembles as he calls out / For another plate of food”). | |
| 266 But apart from that, the sentiment is compelling, | |
| 267 <a href="http://en.wikipedia.org/wiki/Scarlet_Rivera">Scarlet Rivera’s</a> | |
| 268 violin is beautifully scored and played, the tune is to die for, and the | |
| 269 backing vocals are by Emmylou Harris, who you can bet is going to be here in | |
| 270 the 5-✭ series one of these days. | |
| 271 And while there’s not much middle ground on the subject of Dylan’s singing, if | |
| 272 you like it, you’ll <em>really</em> like this song.</p> | |
| 273 <p>Listen to the choruses: Bob and Emmylou veer wildly around the rhythm, then | |
| 274 coalesce on the beat when it matters, and they’re making it | |
| 275 up as they go along, they’re wholly inhabiting the moment, and it’s | |
| 276 quite, quite perfect.</p> | |
| 277 <h2 id='p-3'>Sampling It</h2> | |
| 278 <p>Oh yeah, it’s out there. And there’s a live version too; but the smart | |
| 279 thing would be to go buy the un-compressed un-DRM’ed shiny round silver | |
| 280 version of <cite>Desire</cite>; it’s a keeper.</p> | |

| 295 <p>First of all, implementors of anything Atom-related need to spend some time | |
| 296 <a href="http://golem.ph.utexas.edu/~distler/blog/archives/000793.html">chez | |
| 297 Jacques Distler</a>; in particular, the conversation that plays out in the | |
| 298 comments. Second, there’s this piece of software called | |
| 299 <a href="http://www.planetplanet.org/">Planet Planet</a> that allows you to | |
| 300 make an aggregate web page by reading lots of feeds; for example, see | |
| 301 <a href="http://www.planetapache.org/">Planet Apache</a> or | |
| 302 <a href="http://planetsun.org/">Planet Sun</a>. | |
| 303 Sam Ruby decided that its Atom support needed some work, so | |
| 304 <a href="http://www.intertwingly.net/blog/2006/04/23/Adding-Atom-support-to-PlanetPlanet">he did | |
| 305 it</a>. Now, here’s the exciting part: he pinged me over the weekend and said | |
| 306 “Hey, look at this” wanting to show me his cleverly-Atomized | |
| 307 Planet Intertwingly feed. | |
| 308 I looked at it in | |
| 309 <a href="http://ranchero.com/netnewswire/">NetNewsWire</a> and was puzzled for | |
| 310 a moment; some but not all of the | |
| 311 things in the feed were highlighted as unread, even though this was the first | |
| 312 time I’d seen it. Then the light went on. | |
| 313 This | |
| 314 is Atom doing <em>exactly what we went to all that trouble to make it do</em>. | |
| 315 NetNewsWire has good Atom support and, because Atom entries all have unique | |
| 316 IDs and timestamps, it can | |
| 317 tell that it’s seen lots of those entries before in other feeds that I | |
| 318 subscribe to. That’s how I found Jacques’ piece. This is huge; anyone who | |
| 319 uses synthetic or aggregated feeds knows that dupes are a big problem, showing | |
| 320 up all over the place. | |
| 321 No longer, Atom makes that problem go away.</p> | |

| 336 <p>Check out Dave Hyatt’s | |
| 337 <a href="http://webkit.opendarwin.org/blog/?p=55">excellent write-up</a> on | |
| 338 designing and rendering Web pages so they take advantage of the | |
| 339 higher-resolution screens that <em>may</em> be coming our way. | |
| 340 I emphasize “may” because I’ve seen how slowly we’ve picked up pixels over | |
| 341 the years. The first really substantial screen I ever worked on was a | |
| 342 1988-vintage Sun workstation with about a million pixels. The Mac on my | |
| 343 lap right now, which has 125 times as much memory as that workstation, has | |
| 344 only 1.38 million pixels. | |
| 345 Anyhow, Hyatt has some smart things to say on the issues, | |
| 346 which are trickier than you might think. I suspect that sometime in a couple of | |
| 347 years, if I still care about <span class='o'>ongoing</span>, I’m going to | |
| 348 have to go back and reprocess all the images so that higher-res versions are | |
| 349 available for those who have the screens and don’t mind downloading bigger | |
| 350 files. | |
| 351 Anyhow, Dave’s piece may be slightly misleading in that he talks about SVG | |
| 352 as though | |
| 353 it’s something coming in the future. Not so, check out | |
| 354 <a href="http://zcorpan.1go.dk/sandbox/svg/atom/.xml">this nifty SVG Atom | |

| 420 <p>The notes on usage and source code will return in coming weeks when I get | |
| 421 the cycles to rewrite this whole article.</p> | |
| 422 <h2 id='p-1'>What a “Hit” Means</h2> | |
| 423 <p>I recently | |
| 424 <a href="/ongoing/When/200x/2006/02/07/Thumbnail">updated</a> the | |
| 425 <a href="/ongoing/misc/Colophon"><span class='o'>ongoing</span> software</a> | |
| 426 (but haven’t updated the Colophon I see, oops). | |
| 427 Anyhow, the <code>XMLHttpRequest</code> now issued by each page seems to be a | |
| 428 pretty reliable counter of the number of actual browsers with humans behind | |
| 429 them reading the pages. I checked against | |
| 430 <a href="/ongoing/When/200x/2005/12/04/Google-Analytics">Google Analytics</a> | |
| 431 and the numbers agreed to within a dozen or two on days with 5,000 to 10,000 | |
| 432 page views; interestingly, Google Analytics was always 10 or 20 views | |
| 433 higher.</p> | |
| 434 <p>Anyhow, do <em>not</em> conclude that now I know how many people are | |
| 435 reading whatever it is I write here; because I publish lots of short pieces | |
| 436 that are all there in my RSS feed, and anyone reading my Atom feed gets the | |
| 437 full content of everything. | |
| 438 I and I have <em>no #&*!$ idea</em> how many people look at my feeds.</p> | |
| 439 <p>By the way, this was the first time in weeks and weeks that I’d looked at the | |
| 440 Analytics numbers, and they showed almost exactly zero change from the report | |
| 441 linked above. So I’m going to turn them off; they’re a little too intrusive | |
| 442 and I think may be slowing page loads.</p> | |
| 443 <p>Anyhow, I ran some detailed statistics on the traffic for Wednesday, | |
| 444 February 8th, 2006.</p> | |
| 445 <table cellspacing="3" cellpadding="2" class="wltable"> | |
| 446 <tr valign="top"><td>Total connections to the server</td><td align="right">180,428</td></tr> | |
| 447 <tr valign="top"><td>Total successful GET transactions</td><td align="right">155,507</td></tr> | |
| 448 <tr valign="top"><td>Total fetches of the RSS and Atom feeds</td><td align="right">88,450</td></tr> | |
| 449 <tr valign="top"><td>Total GET transactions that actually fetched data (i.e. status code | |
| 450 200 as opposed to 304)</td><td align="right">87,271</td></tr> | |
| 451 <tr valign="top"><td>Total GETs of actual ongoing pages (i.e. not CSS, js, or | |
| 452 images)</td><td align="right">18,444</td></tr> | |
| 453 <tr valign="top"><td>Actual human page-views</td><td align="right">6,348</td> | |
| 454 </tr> | |
| 455 </table> | |
| 456 <p>So, there you have it. Doing a bit of rounding, if you take the 180K | |
| 457 transactions and subtract the 90K feed fetches and the 6000 actual human page | |
| 458 views, you’re left with 84,000 or so “Web overhead” transactions, mostly | |
| 459 stylesheets and graphics and so on. | |
| 460 For every human who viewed a page, it was fetched almost twice again by | |
| 461 various kinds of robots and non-browser automated agents.</p> | |
| 462 <p>It’s amazing that the whole thing works at all.</p> | |

| 495 <a href="http://www.oreillynet.com/xml/blog/2006/04/xml_in_xml.html">has | |
| 496 upgraded</a> the machine].</i></p> | |
| 497 <h2 id='p-1'>Why “Lark”?</h2> | |
| 498 <p><a href="http://www.laurenwood.org/anyway/">Lauren</a> and I went to | |
| 499 Australia in late 1996 to visit her mother and to get married, which we | |
| 500 did on November 30th. Forty-eight hours later, Lauren twisted her knee | |
| 501 badly enough that she was pretty well | |
| 502 confined to a sofa for the rest of our Australian vacation.</p> | |
| 503 <p>So I broke out my computer and finished the work I’d already started on my | |
| 504 XML processor, and decided to call it Lark for <b>La</b>uren’s <b>R</b>ight | |
| 505 <b>K</b>nee.</p> | |
| 506 <h2 id='p-2'>How Lark Worked</h2> | |
| 507 <p>Lark was a pure | |
| 508 <a href="http://en.wikipedia.org/wiki/Deterministic_finite_state_machine">deterministic | |
| 509 finite automaton</a> (DFA) | |
| 510 parser, with a little teeny state stack. | |
| 511 Some of its transitions were labeled with named “events” that would provoke | |
| 512 the parser to do something if, for example, it had just recognized a start tag | |
| 513 or whatever.</p> | |
| 514 <p>DFA-driven parsers are a common enough design pattern, although I think | |
| 515 Lark is the only example in the XML space. | |
| 516 There are well-known parser generators such as | |
| 517 <a href="http://en.wikipedia.org/wiki/Yacc">yacc</a>, | |
| 518 <a href="http://en.wikipedia.org/wiki/GNU_bison">GNU bison</a>, and | |
| 519 <a href="https://javacc.dev.java.net/">javacc</a>, | |
| 520 usually used in combination with lexical scanners such as | |
| 521 <a href="http://en.wikipedia.org/wiki/Flex_lexical_analyser">flex</a> so that | |
| 522 you can write your grammar in terms of tokens not characters. | |
| 523 Also, they handle LALR langauges, so the parsing technique is quite a bit | |
| 524 richer than a pure state machine.</p> | |
| 525 <p>I thought I had a better idea. The grammar of XML is simple | |
| 526 enough, and the syntax characters few enough, that I thought I could just | |
| 527 write down the state machine by hand. | |
| 528 So that’s what I did, inventing a special-purpose DFA-description | |
| 529 language for the purpose.</p> | |
| 530 <p>Then I had a file called <code>Lark.jin</code> which was really a Java | |
| 531 program that used the state machine to parse XML. The transition “events” | |
| 532 in the machine were mapped to <code>case</code> labels in a huge | |
| 533 <code>switch</code> construct. Then there was a horrible, <em>horrible</em> | |
| 534 Perl program that read the <code>Lark.jin</code> and the automaton, | |
| 535 generated the DFA tables in Java syntax, inserted them into the code and | |
| 536 produced <code>Lark.java</code>, which you actually compiled | |
| 537 to make the parser.</p> | |
| 538 <p>So while Java doesn’t have a preprocessor, Lark did, which made quite a few | |
| 539 things easier.</p> | |
| 540 <p>There were a lot of tricks; some of the state transitions | |
| 541 weren’t on characters, they were on XML character classes such as | |
| 542 <code>NameChar</code> and so on. | |
| 543 This made the automaton easier to write, and in fact, to keep the class files | |
| 544 small, the character-class transitions persisted into the Java form, and the | |
| 545 real DFA was built at startup time. | |
| 546 These days, quick startup might be more important than <code>.class</code> | |
| 547 file size.</p> | |
| 548 <h2 id='p-3'>What Was Good</h2> | |
| 549 <p>It was <em>damn</em> fast. James Clark managed to hand-craft a | |
| 550 Java-language XML parser called | |
| 551 <a href="http://jclark.com/xml/xp/index.html">XP</a> that was a little faster | |
| 552 than Lark, but he did that by clever I/O buffering, and I was determined to | |
| 553 leapfrog him by improving my I/O.</p> | |
| 554 <p>This was before the time of standardized XML APIs, but Lark had a stream API | |
| 555 that influenced SAX, and a DOM-like tree API; both worked just fine. | |
| 556 Lark is one of very few parsers ever to have survived the | |
| 557 <a href="http://www.securityfocus.com/archive/1/303509/2002-12-13/2002-12-19/0">billion | |
| 558 laughs attack</a>.</p> | |
| 559 <p>Lark was put into production in quite a few deployments, and the flow of | |
| 560 bug reports slowed to a trickle. | |
| 561 Then in 1998 I noticed that IBM and Microsoft and BEA and everyone else | |
| 562 were building XML Processors, so I decided that it wasn’t worthwhile | |
| 563 maintaining mine.</p> | |
| 564 <h2 id='p-4'>What Was Bad</h2> | |
| 565 <p>I never got around to teaching it namespaces, which means it wouldn’t be | |
| 566 real useful today.</p> | |
| 567 <p>It had one serious bug that would have been real work to fix and since | |
| 568 nobody ever encountered it in practice, I kept putting it off and never did. | |
| 569 If you had an internal parsed entity reference in an attribute value and the | |
| 570 replacement text included the attribute delimiter (<code>'</code> or | |
| 571 <code>"</code>), it would scream and claim you had a busted XML document.</p> | |
| 572 <h2 id='p-5'>That Automaton</h2> | |
| 573 <p>What happened was, | |
| 574 <a href="http://www.oreillynet.com/pub/au/1712">Rick Jelliffe</a>, who is a | |
| 575 Good Person, was | |
| 576 <a href="http://www.stylusstudio.com/xmldev/200604/post30110.html">looking for | |
| 577 a FSM for XML</a> and I eventually noticed, and so I sent him mine.</p> | |
| 578 <p>There’s no reason whatsoever to keep it a secret: | |
| 579 <a href="/ongoing/code/lark/com/textuality/autom.txt">here it is</a>. | |
| 580 Be warned: it’s ugly.</p> | |
| 581 <p>Fortunately, there were only 227 states and 8732 transitions, so the state | |
| 582 number fit into a | |
| 583 byte; that and the associated event index pack into a short. | |
| 584 To make things even tighter, the transitions were only keyed by characters up | |
| 585 to 127, as in 7-bit ASCII. | |
| 586 Characters higher than that can’t be XML syntax characters, so we’re only | |
| 587 interested whether they fall into classes like <code>NameChar</code> and | |
| 588 <code>NameStartChar</code> and so on. A 64K <code>byte[]</code> array takes | |
| 589 care of that, each byte having a class bitmask.</p> | |
| 590 <p>As a result of all this jiggery-pokery, the DFA ends up, believe it | |
| 591 or not, constituting a <code>short[227][128]</code>.</p> | |
| 592 <p>Here’s a typical chunk of the automaton:</p> | |
| 593 <pre><code>1. # in Start tag GI | |
| 594 2. State StagGI BustedMarkup {in element type} | |
| 595 3. T $NameC StagGI | |
| 596 4. T $S InStag !EndGI | |
| 597 5. T > InDoc !EndGI !ReportSTag | |
| 598 6. T / EmptyClose !EndGI</code></pre> | |
| 599 <p>This state, called <code>StagGI</code>, is the state where we’re actually | |
| 600 reading the name of a tag, we got here by seeing a <code><</code> followed | |
| 601 by a <code>NameStart</code> character.<br/> | |
| 602 Line 1 is a comment.<br/> | |
| 603 In line 2 we name the state, and support error reporting, providing the name | |
| 604 of another state to fall back into in case of error, and in the curly braces, | |
| 605 some text to help build an error message.<br/> | |
| 606 Line 3 says that if we see a valid XML Name character, we just stay in this | |
| 607 state.<br/> | |
| 608 Line 4 says that if we see an XML space character, we move to state | |
| 609 <code>InStag</code> and process an <code>EndGI</code> event, which would stash | |
| 610 the characters in the start tag.<br/>And so on.</p> | |
| 611 <h2 id='p-6'>Other Hackery</h2> | |
| 612 <p>An early cut of Lark used String and StringBuffer objects to hold all the | |
| 613 bits and pieces of the XML. This might be a viable strategy today, but in | |
| 614 1996’s Java it was painfully slow. | |
| 615 So the code goes to heroic lengths to live in the land of character arrays at | |
| 616 all times, making Strings only when a client program asks for one through the | |
| 617 API. The performance difference was mind-boggling.</p> | |
| 618 <h2 id='p-7'>An Evil Idea</h2> | |
| 619 <p>If you look at the automaton, and the Lark code, at least half—I’d bet | |
| 620 three quarters—is there to deal with parsing the DTD and then dealing with | |
| 621 entity wrangling. | |
| 622 A whole bunch more is there to support DOM-building and walking.</p> | |
| 623 <p>I bet if I went through and simply removed support for anything coming out | |
| 624 of the <code><!DOCTYPE></code>, including all entity processing, | |
| 625 then discarded | |
| 626 the DOM stuff, then added namespace support and SAX and StAX APIs, it would be | |
| 627 less than half its current size. | |
| 628 Then if I reworked the I/O, knowing what I know now and stealing some tricks | |
| 629 that James Clark uses in | |
| 630 <a href="http://expat.sourceforge.net/">expat</a>, I bet it would | |
| 631 be the fastest Java XML parser on the planet for XML docs without a | |
| 632 DOCTYPE; by a wide margin. It’s hard to beat a DFA.</p> | |
| 633 <p>And it would still be fully XML 1.0 compliant. Because (snicker) this is | |
| 634 Java, and your basic core Java now includes an XML parser, so I could simply | |
| 635 instrument Larkette to buffer the prologue and if it saw a DOCTYPE with an | |
| 636 internal subset, defer to Java’s built-in parser.</p> | |
| 637 <p>I’ll probably never do it. But the thought brings a smile to my face.</p> | |

| 650 <p>Last weekend, Lauren felt like cooking up home-made Easter eggs, so | |
| 651 the shopping list included “chocolate chips (large bag)”. I was heading down | |
| 652 the bulk-foods aisle and realized one of the vertical acrylic bins was full of | |
| 653 them. Someone had been sloppy, and there was a little heap of chocolate chips | |
| 654 on the shelf underneath it. For a second, I flashed into pure eight-year-old | |
| 655 mode, thinking “Holy cow, there’s a <em>whole bin</em> full of chocolate | |
| 656 chips, and more just lying there!” I popped a few in my mouth and they were | |
| 657 excellent; semi-sweet, dark, strong, and firm. I was still in the state that | |
| 658 Buddhists don’t mean when they say “Child’s Mind”, thinking “I | |
| 659 can get as many as I want!” The list did say “large bag” after all, so I put | |
| 660 a bag under the spout and gleefully jammed the lever <em>all the way | |
| 661 over</em>. At home, Lauren said “You went overboard, a bit, didn’t you?” | |
| 662 and now we have a plastic canister-full in the pantry which should last us | |
| 663 into 2007. It’s a good feeling.</p> | |

| 685 to make a long story short, it almost completely works again. At one point | |
| 686 she seemed nearly infinite in her capabilities, sitting in front of the | |
| 687 computer wrangling software updates while knitting baby stuff and looking up | |
| 688 words in a German dictionary for the kid’s homework. Some of the German nouns | |
| 689 and muttered curses at the Windows install sounded remarkably like each other. | |
| 690 Why would anyone not marry a geek? The only problem is that Win2K won’t | |

| 708 <p>Herewith two hideously ugly little shell scripts for use when Spotlight | |
| 709 refuses to search your mail. | |
| 710 Spotlight is a flawed v1.0 implementation of a really good idea and will, I’m | |
| 711 sure, be debugged in a near-future release. | |
| 712 <i>[Update: The LazyWeb is educating me... these are moving targets.]</i></p> | |
| 713 <p>My problem is that whereas Mail.app will search my To/From/Subject | |
| 714 lines (slowly, and with a | |
| 715 <a href="/ongoing/When/200x/2005/11/20/UnTiger">really irritating GUI</a>), | |
| 716 the “Entire Message” option just doesn’t work, it returns instantly with no | |
| 717 results. Yes, I’ve read the hints about making Spotlight re-index, | |
| 718 but it just flatly refuses to work for me. Mind you, I have a lot of | |
| 719 email, but still, it should at least try.</p> | |
| 720 <p>It turns out I had never really figured out the <code>-print0</code> and | |
| 721 <code>-0</code> idioms that a lot of the shell-command stalwarts now have. | |
| 722 Thanks to Malcolm Tredinnick for raising my consciousness.</p> | |
| 723 <p>This lives in <code>$HOME/bin</code> under the name | |
| 724 <code>mailgrep</code>:</p> | |
| 725 <pre><code>#!/bin/sh | |
| 726 find $HOME/Library/Mail/IMAP* -name '*.emlx' -print0 | \ | |
| 727 xargs -0 fgrep -i $@</code></pre> | |
| 728 <p>Isn’t <code>xargs</code> a funny command? I’ve discovered that it’s nearly | |
| 729 impossible to describe what does, and then why what it does is necessary, but | |
| 730 there are just a whole bunch of places where you’d be lost without it.</p> | |
| 731 <p>This lives in <code>$HOME/bin/mailview</code>:</p> | |
| 732 <pre><code>#!/bin/sh | |
| 733 find $HOME/Library/Mail/IMAP* -name '*.emlx' -print0 | \ | |
| 734 xargs -0 fgrep -i -l -Z $@ | \ | |
| 735 xargs -0 open</code></pre> | |
| 736 <p>The first cut of this dodged <code>xargs</code> and used an | |
| 737 incredibly-inefficient and slow chain of <code>-exec</code> arguments to open | |
| 738 the files one at a time with | |
| 739 <code>view</code> (aka <code>vim</code>), to work around | |
| 740 a well-known <code>vim</code> misfeature; it complained about the input | |
| 741 not being a terminal and left my Terminal.app keystrokes borked.</p> | |
| 742 <p>But Malcolm, confirming my belief in the broken-ness of <code>vim</code>, | |
| 743 said “Oh, *that* ‘view’. I thought it was some sexy Mac ‘view my email’ app”. | |
| 744 D’oh, of course; the magic OS X <code>open</code> command does just the right | |
| 745 thing. | |
| 746 Erm, you might want to run <code>mailgrep</code> before you run | |
| 747 <code>mailview</code>; I’m not sure what would happen if you asked OS X to | |
| 748 open three or four thousand email messages at once.</p> | |

| 762 <p>Friday Slide Scan #28 is two Eighties florals, one interior, one | |
| 763 exterior. With a confession.</p> | |
| 764 <p>First some spring flowers fallen from a tree, just as now in our front | |
| 765 yard, at dusk.</p> | |

| 768 enlarging.</p> | |
| 769 <img src="0713.png" alt="Flowers in shadow with light in background" /> | |
| 770 <p>Here’s the confession. Sometimes on Fridays when I’m feeling kinda | |
| 771 burned-out, I knock off work and do these slide scans in the office, because | |
| 772 this is where I have the | |
| 773 <a href="http://www.tbray.org/ongoing/When/200x/2004/04/14/MineIsBigger">big | |
| 774 screen</a>. | |
| 775 Blowing these pictures up to mega-huge, picking away at the old-slide crud and | |
| 776 scanning artifacts, tinkering with the colour balance, and listening; I never | |
| 777 play music while I’m writing or coding seriously, but I play it real loud while | |
| 778 photo-editing. It’s all pretty well pure pleasure; you just can’t imagine | |
| 779 how good that second one above looks at near-native size. | |
| 780 It reconstitutes the part of my mind that I earn my living with; that’s my | |
| 781 story and I’m sticking to it.</p> | |
| 782 <p>Images in the Friday Slide Scans are from 35mm slides taken between 1953 | |
| 783 and 2003 by (in rough chronological order) | |
| 784 <a href="http://www.textuality.com/BillBray/">Bill Bray</a>, | |
| 785 <a href="/ongoing/When/200x/2004/08/11/MomsGarden">Jean Bray</a>, Tim Bray, Cath | |
| 786 Bray, and | |
| 787 <a href="http://www.laurenwood.org/anyway/">Lauren Wood</a>; when I know | |
| 788 exactly who took one, I’ll say; in this case, at least one is by Cath Bray. | |
| 789 Most but not all of the slides were on Kodachrome; they were digitized using | |
| 790 a Nikon CoolScan 4000 ED scanner and cleaned up by a combination of the Nikon | |
| 791 scanning software and PhotoShop Elements.</p> | |

| 864 <p>James Governor | |
| 865 <a href="http://www.redmonk.com/jgovernor/archives/001526.html">relays a | |
| 866 question</a> that sounds important | |
| 867 but I think is actively dangerous: do AJAX apps present more of | |
| 868 a server-side load? The question is dangerous because it’s meaningless and | |
| 869 unanswerable. Your typical Web page will, in the process of | |
| 870 loading, call back to the server for a bunch of stylesheets and graphics and | |
| 871 scripts and so on: for example, this <span class='o'>ongoing</span> page calls | |
| 872 out to three different graphics, one stylesheet, and one JavaScript file. | |
| 873 It also has one “AJAXy” XMLHttpRequest call. | |
| 874 From the server’s point of view, those are all just requests to dereference | |
| 875 one URI or another. In the case | |
| 876 of <span class='o'>ongoing</span>, the AJAX request is for a static file less | |
| 877 than 200 bytes in size (i.e. cheap). | |
| 878 On the other hand, it could have been for something that required a | |
| 879 complex outer join on two ten-million-row tables (i.e. <em>very</em> | |
| 880 expensive). And one of the virtues of | |
| 881 the Web Architecture is that it hides those differences, the “U” in URI stands | |
| 882 for “Uniform”, it’s a Uniform interface to a resource on the Web that could | |
| 883 be, well, anything. | |
| 884 So saying “AJAX is expensive” (or that it’s cheap) is like saying “A mountain | |
| 885 bike is slower than a battle tank” (or that it’s faster). | |
| 886 The truth depends on what you’re doing with it. | |
| 887 In the case of web sites, it depends on how many fetches you do and | |
| 888 where you have to go to get the data to satisfy them. | |
| 889 <span class='o'>ongoing</span> is a pretty quick web site, even though it runs | |
| 890 on a fairly modest server, but | |
| 891 that has nothing to do with AJAX-or-not; it’s because of the particular way | |
| 892 I’ve set up the Web resources that make the pages here. | |
| 893 I’ve | |
| 894 <a href="/ongoing/When/200x/2006/02/14/AJAX-Performance">argued elsewhere</a> | |
| 895 that AJAX can be a performance win, system-wide; but that argument too is | |
| 896 contingent on context, lots of context.</p> | |

| 912 <p>Graham McMynn is a teenager who was kidnapped in Vancouver on April 4th and | |
| 913 freed, in a large, noisy, and | |
| 914 <a href="http://www.cbc.ca/story/news/national/2006/04/12/bcabduction060412.html">newsworthy</a> | |
| 915 police operation, on April 12th. | |
| 916 <a href="http://en.wikipedia.org/wiki/Hao_Wu">Hao Wu</a> is a Chinese | |
| 917 film-maker and | |
| 918 <a href="http://beijingorbust.blogspot.com/">blogger</a> who was kidnapped in | |
| 919 Beijing on February 22nd in a | |
| 920 small, quiet police operation not intended to be newsworthy, and who has not | |
| 921 been freed. | |
| 922 Read about it | |
| 923 <a href="http://spaces.msn.com/wuhaofamily/">here</a>, | |

| 926 Making noise about it <em>might</em> influence the government of China to | |
| 927 moderate its actions against Mr. Wu, and can’t do any harm. | |
| 928 Mr. McMynn’s kidnappers were a gaggle of small-time hoodlums, one of whom was | |
| 929 out on bail while awaiting trial for another kidnapping (!). | |
| 930 Mr. Wu’s were police. | |
| 931 In a civilized country, the function of the police force is to deter such | |
| 932 people and arrest them. A nation where they are the same people? Nobody | |
| 933 could call it “civilized”.</p> | |
