| kanzure- | I was figuring I'd write it myself, based off of data structures for representing assemblies and assembling of things. | 17:06 |
| kanzure- | also, writing a crawler for dellsocialinnovation.com is a pain in the ass. | 17:08 |
| xp_prg | kanzure- use perl mechanize problem solved | 17:18 |
| xp_prg | or python mechanize | 17:18 |
| kanzure- | not true. | 17:24 |
| kanzure- | perl mechanize does not implement javascript | 17:24 |
| * katsmeow-afk has an offtopic question | 17:24 | |
| xp_prg | so | 17:24 |
| xp_prg | why do you need javascript to do a crawler? | 17:25 |
| kanzure- | xp_prg: because the site uses javascript. | 17:25 |
| kanzure- | what's hard to understand about that? | 17:25 |
| xp_prg | I am not aware of any crawler that utilizes javascript | 17:25 |
| kanzure- | (and yes, I've been sitting here tracing through the javascript by hand for a while now.) | 17:25 |
| kanzure- | katsmeow-afk: yes? | 17:25 |
| xp_prg | kanzure- honestly, what our doing is crazy | 17:26 |
| kanzure- | what? | 17:26 |
| xp_prg | a crawler used some kind of library to web screenscrape | 17:26 |
| xp_prg | what the heck are you doing? | 17:26 |
| kanzure- | so you're making random opinions about what I'm doing without first knowing what I'm doing? | 17:27 |
| xp_prg | you said your making a crawler | 17:27 |
| kanzure- | I'm helping a friend win $50k | 17:27 |
| katsmeow-afk | given a 386 , dos 5.0, and 2 gigs of physical memory, loading and running a 32bit protected mode application will require no memory virtualisation, and no use of dos memory handlers (once in protected mode), and only the dpmi to talk to dos,, right? | 17:27 |
| xp_prg | what is there to understand? | 17:27 |
| kanzure- | xp_prg: basic english. | 17:27 |
| kanzure- | katsmeow-afk: I have absolutely no idea how DOS 5.0 allocates memory :-(. | 17:27 |
| xp_prg | kanzure- why do you need to understand javascript? | 17:28 |
| katsmeow-afk | well, it's more about protected mode vs any other mode on a 386 or better cpu | 17:28 |
| kanzure- | that's like asking "why do you need to understand english" | 17:28 |
| katsmeow-afk | it's not about which dos version | 17:28 |
| xp_prg | but why does your crawler need to understand it? | 17:29 |
| kanzure- | it doesn't. but if you were going to say "problem solved" by pointing to perl WWW::Mechanize, then it needs to interpret and run javascript | 17:29 |
| kanzure- | which it doesn't. | 17:29 |
| kanzure- | so the problem is *not* solved | 17:29 |
| xp_prg | kanzure- just look at what the javascript is ending then automate that in javascript | 17:30 |
| kanzure- | what the fuck do you think I meant when I said "I've been sitting here tracing through the javascript by hand for a while now." ? | 17:30 |
| xp_prg | well what were you going to use for the crawler? | 17:31 |
| kanzure- | I'm done talking to you | 17:31 |
| * kanzure- goes home | 17:31 | |
| xp_prg | kanzure- are you not making a program to do the crawling? | 17:31 |

| kanzure | what does that question have to do with anything? | 17:50 |

| kanzure | what? | 17:51 |

| kanzure | The 16x8 heater array used to initiate Marangoni flow consists of #0603 surface-mount resistors (1x0.8x0.3 mm) placed at 1.9 mm pitch on a two sided printed circuit board (PCB) (Fig. 4.5). The 100 Ω resistors are electrically connected via thru-holes to the opposite side of the PCB which provides routing, cable connectors, and a heat sink (Fig. 4.6). This two sided design allows the resistors to be placed near the liquid without obstruction. Commercial foundries are used to manufacture PCBs (Sunstone Circuits, Mulino OR) and to assemble the resistors in a solder reflow process (Screaming Circuits, Canby OR). | 19:41 |
| kanzure | huh, so Basu only uses single plates of glass, rather than sandwhiching for surface tension effects | 19:42 |
| kanzure | guess he doesn't really care since he gets it via Marangoni forces | 19:43 |

| kanzure | yep, just read that a few minutes ago (the second to last one you cited) | 20:25 |
| kanzure | apparently it involved thermocapillary channels that were self-regulating to heat | 20:25 |
| katsmeow-afk | didn't i see somewhere, a cpu was built in liquid cooling channels on the die? not a heatsink? | 20:25 |
| kanzure | that's right | 20:26 |
| katsmeow-afk | where did i see that? | 20:26 |

| kanzure | that was it. | 20:26 |
| katsmeow-afk | no, not droplets | 20:26 |
| kanzure | oh | 20:26 |
| kanzure | hrm | 20:26 |
| katsmeow-afk | the idea was micro pumps pushing liquid thru the hottest areas of a cpu die, and then out to a interface to a external system | 20:27 |
| kanzure | heh, you need to use a thermally-expanding liquid, which would then push itself through to cooler areas or something | 20:27 |
| katsmeow-afk | Several years ago, a chip with thermal densities above 10 W/cm.sup.2 was the norm; presently, even silicon chips have been designed with power densities of 350 W/cm.sup.2. Prototype versions of gallium nitride and silicon carbide chips have been demonstrated "in the laboratory" operating at power densities in the range of 1500-3500 W/cm.sup.2 and III-V compound semiconductor chips operate in the range of 450 W/cm.sup.2. | 20:28 |
| katsmeow-afk | that was the problem to be solved | 20:28 |
| katsmeow-afk | Chip cooling by directly pumping a working fluid such as fluorocarbon onto the chip(s) has been developed and cutting microchannels in the back of the chips and pumping liquid through the microchannels has been developed in an effort to operate at these power densities. | 20:29 |
| katsmeow-afk | Developed at the Georgia Institute of Technology, the wafer-level fabrication technique includes polymer pipes that will allow electronic and cooling interconnections to be made simultaneously using automated manufacturing processes. | 20:34 |

| katsmeow-afk | June 21, 2005 | 20:35 |
| katsmeow-afk | Beating the Heat: Liquid Cooling Technique Uses Microfluidic Channels Integrated onto the Backs of Chips | 20:35 |

| kanzure | hm. | 20:36 |
| katsmeow-afk | microscopic | 20:36 |
| katsmeow-afk | “The challenge of 3D integration now is that if you have several chips stacked on one another, there is no way to cool the chips in between,” Dang said. “If we have microchannels on the back side of each chip, we could pump liquid through them and cool all of the chips.” | 20:37 |
| katsmeow-afk | so you can add cache chips to the middle of a cpu core, and save transit time out to the cache at the perimeter | 20:38 |
| katsmeow-afk | etc | 20:38 |
| katsmeow-afk | The Georgia Tech researchers, who include Paul Joseph, Muhannad Bakir, Todd Spencer, Paul Kohl and James Meindl, begin by etching trenches more than 100 microns deep on the back of the silicon wafer. | 20:38 |
| kanzure | wait, cache chips aren't there because of heating issues? | 20:39 |
| kanzure | yeah, trench etching / trench digging started by running sharp pointy sticks (well, wires) through wax in the 50s or 60s. | 20:39 |
