Re: [FRIAM] Delicious Alternative
Thanks Owen. Since I use only firefox and only one computer, I can see why I have never felt the need.. Whew!

Nick: this lets you search your bookmarks, sorta like your own personal google on the pages you've shown interest in the past. Also: the browsers have plugins which make it easy to add a widget that quickly add the current page you are looking at to your cloud bookmarks. And if you've selected any data on that page, it becomes a note, also for searching.

Re: [FRIAM] Cell Service/Tower/Reception/Repeaters/etc.
Gil - Thanks! Very Interesting! My iPhone does have a field test mode (*3001#12345#*) which does expose the alternate towers that it sees (and might use). I see no indication anywhere that I could influence it's choice, nor have I been able to find a concise description of the algorithm/heuristics likely used to decide. The most obvious of course, would seem to be signal strength, but that ignores issues such as congestion. Since GSM is a Frequency Division Multiplex hybridized with Time Division Multiplex, it seems like there would be almost immediate feedback to the mobile device as it tries to connect as to whether there even *was* an available time/frequency slot to use... the heuristic could be as simple as try the strongest signal you see, if it is full, try the next, repeat. Along with a dB indication of (useable?) signal there is something called RSSI (received signal strength indicator) which seems useful for recognizing how much interference in the band there might be. It tops out at about 50 underneath a tower but is as low as 5 when still useable. Multiple towers competing and/or possibly other sources of interference run this number up without running up the useable signal. There are two very cryptic numbers, C1 and C2 which from the mumbo jumbo I've found, might relate to the heuristic which I was seeking above... but I don't know yet... this is subtle and complicated stuff and it appears that short of finding a professional training course, there isn't much information laying around for the motivated layman. See what we have become in this Internet/Google/Wikipedia age? We DO expect a LOT! Depending on the phone there might be a # code to get it to search for more frequencies. Might take a bit of diging though. My oold Cinguluar phone for instance used #689# that let it borrow other towers in range. I'll check for the potenial andriod # codes to see if there's something simillar.

I took up Gary Nelson's question about Cell Towers/Coverage, my own frustrations, and the other resulting conversations to do a little research and see if I could learn more and maybe even fix up some of my own problems/challenges. I'm testing iPhone 2, 3G, 4 against ATT and T-Mobile SIMS right now. Mostly at my house (very marginal signal if any) but will be doing other places. I'm looking at Cell Repeaters (primarily for my home, but maybe also mobile). I'm therefore *mostly* sorting out GSM related issues, but there is a lot of overlap in general RF issues, repeaters, tower locations, etc. I started trying to write up what I know (so far) and discovered that (as often is the case) the more I know, the more I know I don't know. My 3rd Class Radiotelephony license from 1974 and a BS in Physics provides just enough background to get me in trouble. I wrote a long, rambly overview of what I know (dominated by what that made me realize I *didn't* know) and decided most of you don't care. So, if there are others trying to make actionable sense (or merely slake your curiosity) about the issues of Cell Reception and the potential use of Repeaters, ping me and we can discuss offline. Maybe once we learn enough, one or more of us can write up a (more) concise lessons learned. My long-winded ramble was useful (to me) already, as trying to explain it to the larger crowd caused me to dig just a little deeper than I was for more practical reasons. Now to get my nose back on the practical grindstone. - Steve -- 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 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 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] OpenCL class
We are going to have a change in the meeting times of the openCL class: Days: Thursday (13th) followed by Wednesday (19th) and Friday (21st) Times: 1:30p on each day Sorry for any confusion! We'll get this on the SFX calendar asap. And folks planning to attend, keep letting us know. It should be great to see how the rest of the GPU gets used .. i.e. from openGL to openCL! Please do drop by. -- Owen On Fri, Oct 7, 2011 at 6:40 PM, Owen Densmore o...@backspaces.net wrote: Robert Geist, who spoke recently at SFX (see below) has offered to lead a 3 day class on OpenCL!

Whether models are physically-based or procedural, model processing is almost always characterized by substantial computational demands which have almost always precluded real-time performance. Nevertheless, the recent development of new, highly parallel computational models, coupled with dramatic performance improvements in GPU-based execution platforms, has brought real-time modeling and rendering within reach. The talk will focus on the natural synergy between GPU-based computing and the so-called lattice-Boltzmann methods for solutions to PDEs. Examples will include photon transport for global illumination and modeling and rendering of atmospheric clouds, forest ecosystems, and ocean waves. *BIO*: Robert Geist is a Professor in the School of Computing at Clemson University. He served as Interim Director of the School in 2007-2008, and he is co-founder of Clemson's Digital Production Arts Program. He received an M.A. in computer science from Duke University and a Ph.D. in mathematics from the University of Notre Dame. He was an Associate Professor of Mathematics at the University of North Carolina at Pembroke and an Associate Professor of Computer Science at Duke University before joining the faculty at Clemson University. He is a member of IFIP WG 7.3, a recipient of the Günther Enderle Award (Best Paper, Eurographics), and a Distinguished Educator of the ACM. http://www.cs.clemson.edu/~geist/homepage.html 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
