You have probably used a device with a 6502\, and maybe even programmed one\, but do you know th e historical context for it and what made it successful? This talk brief ly covers the following aspects of the 6502: the events that lead to its creation\, the elegance of the design\, and the lessons we can learn fr om its success. \;\n \;\nSpeaker Bio: \;\nJason Dagit is a rese arch engineer at Galois. He received a M.S. in Computer Science from Ore gon State University in 2009. He has been active in the Haskell communit y since 2005 and he is currently a member of the Haskell.org committee. His areas of interest include functional programming\, computer graphics \, and most recently hardware design. He enjoys working in the space bet ween pure research and industrial practice. \;\n \;\n7:30pm \;\ nPopcount as an Example Of Microbenchmarking in C \;\n \;\nQuickly determining the number of 1 bits in a binary machine \;\nword\, the so-called "\;popcount"\;\, has always been an \;\ninteresting problem for developers. Popcount is useful in \;\napplications rangi ng from cryptography to games\, so it is \;\nworth trying to optimize . In this talk\, I will report on a \;\nnumber of different popcount algorithms and their C \;\nimplementation performance\, in the contex t of a \;\n"\;microbenchmarking"\; framework custom-built in C for this \;\npurpose. I will also explore the pitfalls of C in \ ;\nmicrobenchmarking and the issues\, problems and relevance of \;\nm icrobenchmarking in general. \;\n \;\nSpeaker Bio: \;\nBart Mas sey got his B.A. in Physics from Reed in 1987\, \;\nhaving learned C while he was there. After a couple of years \;\nwriting C code at Tek tronix\, Inc. Bart attended University \;\nof Oregon\, where he recei ved his MSCS in 1992 and his \;\nPh.D. in 1999. For the past 14 years \, he has been a Computer \;\nScience Professor at Portland State Uni versity. He still \;\nwrites more C than he cares to admit. \;\n&# 13\;\n8:30ish pm \;\nHead to an elevator. People might go someplace t o continue chatting. \;\n \;\nARRIVING BY BIKE? \;\n \;\nCy clists are welcome to park their bikes in the New Relic office. Bikes ar e not allowed in the building lobby\, however\, and must use the freight elevator. To get your bike up to the 28th floor\, enter the building's parking lot by going down the ramp at 5th and Pine. Go past the booth -- no need to pick up a ticket -- and turn right. Go straight until you al most run into the elevator lobby\, then go right again. On the back side of the elevator block you'll see a beat up pair of double doors marked "\;freight elevator."\; You can get up by buzzing in with the in tercom\, and saying you're here for New Relic. Ride on up to the 28th fl oor\, you'll easily find the bike parking. \;\n \;\nA Huge thanks to New Relic for providing the venue and food. \;\n \;\nThanks to O'Reilly for sending books.\n\nTags: C\, C++\, cpp\, ASM\, assembly\, co mpiled\, rust\, epdx:group=pdxbyte\n\nImported from: http://calagator.or g/events/1250465681 URL:http://pdxbyte.org SUMMARY:pdxbyte users group first meeting (C/C++/Assembly) LOCATION:New Relic: 111 SW 5th Avenue\, Suite 2700\, Portland Oregon 9720 4 United States SEQUENCE:6 END:VEVENT BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20140319T194336Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20140408T210000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20140408T180000 DTSTAMP;VALUE=DATE-TIME:20140319T194336Z LAST-MODIFIED;VALUE=DATE-TIME:20140404T203222Z UID:http://calagator.org/events/1250465871 DESCRIPTION:First talk at 7PM\, come early to hack\, or network \;\n&# 13\;\n* 7pm \;\nTitle: \;\nRestoration of a simulator of one great machine on another. \;\n \;\nAbstract: \;\nGordon Bell describ ed Seymour Cray as the greatest computer builder that he knew of as demo nstrated by his designs and their successors that operated at the highes t performance for over 30 years. Bell was from DEC\, Cray from CDC\, two routine producers of beautiful architectures. I programmed both. In thi s talk I will review the restoration of my work based on the patterns wi dely used in assembler of the time. This itself is an innovation in rest oration and well suited to the modern web. \;\n \;\nBio: \;\nWa rd Cunningham has worked for and consulted to daring startups and huge c orporations. He has served as CTO\, Director\, Fellow\, Principle Engine er and Inventor. He is best known for creating wiki. He leads an open-so urce project rebuilding wiki to solve more complex sharing situations ad dressing some of societies toughest problems. Ward founded movements in object-oriented\, agile software\, extreme programming and pattern langu ages. Ward lives in Portland\, Oregon and works for New Relic\, Inc. \;\n \;\n* 7:30pm \;\nTitle: \;\nBuilding Things With SDL"\ ; (Simple DirectMedia Layer) http://www.libsdl.org/ \;\n \;\nAbstr act: \;\nAn overview of the Simple DirectMedia Layer and some of the things you can do with it and basic howto bits. \;\n \;\nBio: \ ;\nJason ChampionJason Champion\, Software Mad Scientist. \n\nTags: C\, C++\, cpp\, ASM\, assembly\, compiled\, rust\, epdx:group=pdxbyte\n\nImp orted from: http://calagator.org/events/1250465871 URL:http://pdxbyte.org SUMMARY:pdxbyte users group (C/C++/Assembly) LOCATION:New Relic: 111 SW 5th Avenue\, Suite 2700\, Portland Oregon 9720 4 United States SEQUENCE:6 END:VEVENT BEGIN:VEVENT CREATED;VALUE=DATE-TIME:20140423T224806Z DTEND;TZID=America/Los_Angeles;VALUE=DATE-TIME:20140513T210000 DTSTART;TZID=America/Los_Angeles;VALUE=DATE-TIME:20140513T180000 DTSTAMP;VALUE=DATE-TIME:20140423T224806Z LAST-MODIFIED;VALUE=DATE-TIME:20140510T040430Z UID:http://calagator.org/events/1250466061 DESCRIPTION:First talk at 7PM\, come early for networking\, or hacking.&# 13\;\n \;\n \;\nIntroduction to Splay Trees \;\n \;\nWhat\, why and how they can be used. I'll go over how splaying works\, how we u se it in OlegDB\, why it can be a better choice than binary trees for ce rtain situations and how the splaying algorithm can/can't be applied to other kinds of trees. \;\n \;\nQuinlan Pfiffer: OlegDB coauthor 3\;\n \;\n \;\n \;\nx86 machine language programming in the bas h shell \;\n \;\nCompilers\, and assemblers are seemingly magical programs that turn text into something the CPU can process directly.
