2/13 Question about memory relocation: These days most h/w has a relocation register. Could the relocation address be stored on disk or in kernel memory vs. in a register? Yes, that would be slow but is it possible? Do you *need* a relocation register or does it exist purely for performance reasons? I was reading some paper written by IBM in the 1960s that seemed to imply the former and I don't understand why that would be. \_ What "relocation register" is this? If you're talking about the one that (say) the IBM 7090 used for time-sharing, that's been obsolete for 30 years; modern machines use virtual memory. (And the tables defining the virtual-memory mapping are in fact stored in kernel memory, since they're too big to fit in a register.) Or did you have something else in mind? \_ Yes, but modern machines still have a base register. Do they need it? \_ What do you mean by a "base register"? It would help if you could say exactly which register you're talking about on some real architecture (x86, PowerPC, MIPS, etc.), or at least if you could describe what this register does. \_ Because comparing 1960s computer hardware to today's is like asking why drivers need a whip to make their cars drive faster because you saw a picture of a horse drawn carriage. \_ Well, no. Modern hardware still does it that way. The question is: Does it *have* to? |

2/13 Bubbles have repeatedly plagued Western finance since its origins in the Italian Rensiassance: http://tinyurl.com/c83pfd (The Economist) (and an explaination why the CDS trades should "net to zero") \_ They won't net to 0 if some people go bankrupt, drops out of the system and can't pay up. Finance is not a zero sum game. \_ Top people to blame for the financial crisis: http://www.time.com/time/specials/packages/article/0,28804,1877351_1877350,00.html http://www.time.com/time/specials/packages/article/0,28804,1877351_1877350_1877320,00.html http://www.time.com/time/specials/packages/article/0,28804,1877351_1878509_1878508,00.html |

2/13 Follow-up for "moral of the story" guy: http://news.bbc.co.uk/2/hi/asia-pacific/7885078.stm Arrests follow China tower fire "Twelve people have been detained in connection with a fire that partly destroyed the unfinished headquarters of China's state broadcaster." Moral of the story: break the law, go to firing squad. \_ What makes you think these guys are going to the firing squad? \_ Hyperbole. Assumptions about PRC's legal system. |

2/13 Can someone get Lea Kissner of Google back on motd? \_ Why don't you try and do this, since you care? \_ She's married. She's just not that into you. \_ I just want to thank her for exposing remote office pains where no one from remote offices dares to say it. You know, you just can't say anything bad when you're in the system, so to speak. Conformity means survival and all. I bet Jeff Dean and Urs would be proud of her observation, honesty, and transparency. -borg mon \_ did she echo "SUCK IT!!!!!" | mail -s "YES YOU" staff@google.com \_ did she echo "SUCK IT!!!!!" | mail -s "YES YOU" \ staff@google.com \_ No, she said "Ive been told that you guys suck" | mail -s "management sucks" oc_emg@google.com everyone@google.com It takes a lot of guts to do that. \_ I asked for more details but he said "I think she just bit off a little more than she can chew." \_ This is the hottest photo ever http://research.google.com/pubs/people_images/20709.jpg \_ removed stupid comment. -!Lea \_ Dude, it was early on my first day of work. Deal. -Lea \_ OK, I've been invoked. :) I'd like to talk; I didn't think I said anything particularly revolutionary. Try chialea@gmail.com. If you're really paranoid, call my cell. The number's on my work contact page. - Lea of Google \_ I'd recommend against talking privately with strangers. Anything you write over email will probably end up on ValleyWag. Either don't talk about it or might as well talk publicly. \_ I can verify that someone's a Googler and thus covered under the same NDA as I am. Security-team knows... well, not all, but a lot. - Lea |
